NI 数据采集卡使用入门
NI 数据采集卡使用入门NI 数据采集卡使用入门一、安装与配置:1. 在安装板卡之前，请首先安装NI-DAQ驱动程序软件。
您可以在随卡附带的光盘内找到这个驱动程序软件。
另外，NI公司的网站上也提供这个驱动程序软件的免费下载：/softlib.nsf/websearch/90B60D5899BCCCDB86256FC700581B89?opendocument&node=132070_US如果您使用LabVIEW或LabWindows/CVI 等软件来进行编程,需要在安装驱动软件之前先安装开发平台LabVIEW或LabWindows/CVI等软件。
安装过程中，安装程序会提醒您插入DAQ驱动光盘。
2. NI-DAQ驱动软件正确安装后,请关闭计算机,插入数据采集板卡,启动计算机,即可自动找到板卡并安装好，完成整个安装过程。
注意：在安装PCI或者PXI板卡时，一定要将电脑电源关闭；PC机则最好将电源线拔掉，以免电脑主板关机后仍然带电，造成各类损伤。
二、模拟输入说明1. 信号类型根据信号的参考情况，一个电压源可以分为两类：接地信号、浮地信号。
接地信号:接地信号是信号的一端直接接地的电压信号。
它的参考点是系统地（例如大地或建筑物的地）。
最常见的接地信号源是通过墙上的电源插座接入建筑物地的设备，例如信号发生器和电源供电设备等。
浮地信号:一个不与任何地（如大地或建筑物的地）连接的电压信号称为浮地信号。
一些常见的浮地信号有电池、热电偶、变压器和隔离放大器。
2．测量方式按信号连接方式不同可分为三种测量方式：差分(DIFF)；参考单端(RSE)；非参考单端（NRSE）。
注意：NI公司的部分型号数据采集卡不一定完全支持上述三种测量方式，请查询对应数采卡的使用手册。
按测量方式分类可以分为以下两大类测试系统：1）差分测试系统(DIFF)n 可避免接地回路干扰n 可避免因环境引起的共模干扰当输入信号有以下情况时，使用差分测试系统：n 低电平信号（例如小于1V）。

Industrial Digital I/O Device for USB –60 V, Channel-to-Channel IsolatedOverview and ApplicationsThe National Instruments USB-6525 is a full-speed USB device with eight normally open, channel-to-channel isolated, solid-state relay outputs and eight ±60 VDC channel-to-channel isolated digital inputs. The NI USB-6525 offers features for industrial control and manufacturing test applications, such as factory automation, embedded machine control, and production line verification. The solid-state relay outputs have a 60 VDC/30 V rms switching voltage and 500 mA/ch maximum switching current, making them ideal for controlling pumps, valves, motors, and other industrial actuators. The eight isolated digital input channels break ground loops and offer protection from noise and spikes on external signals. You can also use one of the digital input channels as a 5 kHz, 32-bit event counter for counting digital pulses.HardwareThe USB-6525 has eight channel-to-channel optically isolated inputs,P1.<0..7>, and eight channel-to-channel optically isolated, solid-state relay outputs, P0.<0..7>. The isolated inputs consist of an optocoupler, a depletion-mode MOSFET-based current-limiting circuit, and a Schottky diode. Each channel has its own positive and negative terminals capable of detecting a wide range of DC signals, from 5 V TTL logic levels to DC power supply levels up to 60 V.PFI 0 (an alias to P1.7) can also function as the source for a 32-bit counter. In this mode, the device counts low to high transitions on P1.7. You can arm and disarm the counter as well as read or reset the count through software.You can connect loads to the solid-state relay outputs with an AC or DC power source. The default power-on state of the solid-state relays is open. The relays also remain open when the computer and the USB-6525device are powered off.•Small, portable digital I/O device •Eight channel-to-channel optically isolated inputs (±60 VDC)•Eight channel-to-channel optically isolated, solid-state relay outputs (60 VDC/30 V rms max)•500 mA maximum switching current per channel•One 32-bit event counter•Full-speed USB (12 Mb/s) bus interface •Built-in, removable connectors for easy connectivity•USB cable strain relief Operating Systems•Windows Vista/XP/2000Recommended Software •LabVIEW•LabWindows™/CVI •Measurement Studio •LabVIEW SignalExpressOther Compatible Software •Visual Studio .NET•C, C++•Visual BasicMeasurement Services Software (included)•NI-DAQmx driver software •Measurement & Automation Explorer configuration utility•LabVIEW SignalExpress LEdata-logging softwareNI USB-6525IsolationIsolation is a form of built-in signal conditioning that provides an extended voltage range for direct connectivity to industrial sensors and actuators. The USB-6525 provides channel-to-channel isolation where each channel is physically and electrically separated from the others. Isolation provides three main benefits:1.Safety from hazardous high voltages and transients2.Rejection of common-mode voltages3.Removal of ground loopsSafety from High-Voltage TransientsIsolation electrically separates high-voltage front-end channels from each other and the low-voltage back end of the USB-6525. Signalsare passed between the two sections of the device using optocouplers. By separating the two sections, any voltages within the isolation specifications are prevented from entering the USB bus section or other channels. Isolation provides protection for the user, data acquisition system, and measurement data.Common-Mode Voltage RejectionA voltage common to both sides of a differential circuit pair iscalled common-mode voltage. This phenomenon is typical in noisy environments containing machinery and inductive loads. The differential voltage across the circuit pair is the desired signal, whereas the common voltage signal is the unwanted signal that may have been coupled into the transmission line. The USB-6525 can measure signals from lines with signal plus common-mode voltage of up to 60 VDC.Ground Loop RemovalGround loops are the most common source of noise in data acquisition applications. They occur when two connected terminals in a circuit are at different ground potentials, causing current to flow between thetwo points. This additional voltage can cause significant error in the measurement. When a ground loop exists, the measured voltage isthe sum of the signal voltage and the potential difference that exists between the signal source ground and the measurement system ground. This potential is generally not a DC level; therefore, the result is a noisy measurement system. By offering an isolated floating ground on the front end, the isolated USB-6525 devices are able to prevent ground loops from forming.SoftwareNational Instruments measurement services software, built aroundNI-DAQmx driver software, includes intuitive application programming interfaces, configuration tools, I/O assistants, and other tools designed to reduce system setup, configuration, and development time.

However, the individual channels are not isolated from each other. The EX+, EX-, and T- signals are common among all channels. You can connect the NI 9237 to a device that is biased at any voltage within the NI 9237 rejection range of earth ground.Figure 1. Input Circuitry for One Channel of the NI 9237Connection Options to Correct for Resistance Errors Wiring resistance can create errors in bridge circuits. The NI 9237 provides two mechanisms to correct for these errors: remote sensing and shunt calibration.Remote SensingRemote sensing continuously and automatically corrects for errors in excitation leads, and generally is most appropriate for half- and full-bridge sensors.Long wire and small gauge wire have greater resistance, which can result in gain error. The resistance in the wires that connect the excitation voltage to the bridge causes a voltage drop, 4| | NI 9237 Datasheetwhich is a source of gain error. The NI 9237 includes remote sensing to compensate for this gain error. Connect remote sense wires to the points where the excitation voltage wires connect to the bridge circuit. Refer to the following figure for an illustration of how to connect remote sense wires to the NI 9237.Figure 2. Connecting Remote Sense Wires to the NI 9237RRThe actual bridge excitation voltage is smaller than the voltage at the EX+ and EX- leads. If you do not use remote sensing of the actual bridge voltage, the resulting gain error is:BB BBB for half‐bridge sensors and2⋅BBBBB for full‐bridge sensors.If you connect the remote sense signals directly to the bridge resistors, the NI 9237 senses the actual bridge voltage and eliminates the gain errors caused by the resistance of the EX+ and EX- leads.Shunt CalibrationShunt calibration can correct for errors from the resistance of both the excitation wiring and wiring in the individual resistors of the bridge. Remote sensing corrects for resistances from the EX pins on the NI 9237 to the sensor, and shunt calibration corrects for these errors and for errors caused by wire resistance within an arm of the bridge. Shunt calibration is most useful with quarter-bridge sensors because there may be significant resistance in the wiring to the active resistor in the bridge.The NI 9237 shunt calibration circuitry consists of a precision resistor and a software-controlled switch. Refer to the software help for information about enabling the shunt calibration switch for the NI 9237.Shunt calibration involves simulating the input of strain by changing the resistance of an arm in the bridge by some known amount. This is accomplished by shunting, or connecting, a large resistor of known value across one arm of the bridge, creating a known strain-induced change in resistance. You can then measure the output of the bridge and compare it to the expected voltage value. You can use the results to correct gain errors in the entire measurement path, or to simply verify general operation to gain confidence in the setup.NI 9237 Datasheet| © National Instruments| 5Use a stable signal, which is typically the unloaded state of the sensor, first with the shunt calibration switch off and then again with the switch on. The difference in these two measurements provides an indication of the gain errors from wiring resistances. You can design the software application to correct subsequent readings for this gain error.Excitation VoltagesYou can program the NI 9237 to supply 2.5 V , 3.3 V , 5 V , or 10 V of excitation voltage. Themaximum excitation power for internal excitation is 150 mW.Note Unless you supply external excitation voltage, NI recommends that you setthe excitation voltage to a value that keeps the total power below 150 mW. The NI 9237 automatically reduces internal excitation voltages as needed to stay below 150 mW total power.Use the following equation to calculate the power of a single bridge:=B 2where R is the total resistance of the bridge.For a quarter or half bridge, R is equal to two times the resistance of each element. For a full bridge, R is equal to the resistance of each element.The 150 mW limit allows you to power half and full bridges as follows:•Four 350 Ω half bridges at 5.0 V •Four 350 Ω full bridges at 3.3 V •Four 120 Ω half bridges at 2.5 VExternal ExcitationYou can connect an external excitation voltage source to the NI 9237 if you need an excitation voltage that causes more than 150 mW to dissipate across all the bridges.Figure 3. Connecting an External Excitation Voltage Source to the NI 9237External Excitation VoltageSourceExternal Excitation Voltage SourceNote For the NI 9237 with RJ-50, use the two EX+ and EX- terminals on the four-terminal external excitation voltage connector to connect one external excitation source.You can use the additional EX+ and EX- terminals on the connector to wire multiple NI 9237modules together in a daisy chain.6 | | NI 9237 DatasheetFilteringThe NI 9237 uses a combination of analog and digital filtering to provide an accurate representation of in-band signals and reject out-of-band signals. The filters discriminatebetween signals based on the frequency range, or bandwidth, of the signal. The three important bandwidths to consider are the passband, the stopband, and the anti-imaging bandwidth.The NI 9237 represents signals within the passband, as quantified primarily by passband ripple and phase nonlinearity. All signals that appear in the alias-free bandwidth are either unaliased signals or signals that have been filtered by at least the amount of the stopband rejection.PassbandThe signals within the passband have frequency-dependent gain or attenuation. The small amount of variation in gain with respect to frequency is called the passband flatness. Thedigital filters of the NI 9237 adjust the frequency range of the passband to match the data rate.Therefore, the amount of gain or attenuation at a given frequency depends on the data rate.Figure 4. Typical Passband Flatness for the NI 9237Frequency/Data Rate0.50.40.0250.000–0.025–0.0500.30.20.10G a i n (d B)StopbandThe filter significantly attenuates all signals above the stopband frequency. The primary goal of the filter is to prevent aliasing. Therefore, the stopband frequency scales precisely with the data rate. The stopband rejection is the minimum amount of attenuation applied by the filter to all signals with frequencies within the stopband.Alias-Free BandwidthAny signals that appear in the alias-free bandwidth are not aliased artifacts of signals at a higher frequency. The alias-free bandwidth is defined by the ability of the filter to reject frequencies above the stopband frequency. The alias-free bandwidth is equal to the data rate minus the stopband frequency.NI 9237 Datasheet | © National Instruments | 7Data RatesThe frequency of a master timebase (f M) controls the data rate (f s) of the NI 9237. The NI 9237 includes an internal master timebase with a frequency of 12.8 MHz, but the module also can accept an external master timebase or export its own master timebase. To synchronize the data rate of an NI 9237 with other modules that use master timebases to control sampling, all of the modules must share a single master timebase source.The following equation provides the available data rates of the NI 9237:=÷256where n is any integer from 1 to 31.However, the data rate must remain within the appropriate data rate range. When using the internal master timebase of 12.8 MHz, the result is data rates of 50 kS/s, 25 kS/s, 16.667 kS/s, and so on down to 1.613 kS/s depending on the value of n. When using an external timebase with a frequency other than 12.8 MHz, the NI 9237 has a different set of data rates.Note The NI 9151 R Series Expansion chassis does not support sharing timebasesbetween modules.NI 9237 SpecificationsThe following specifications are typical for the range -40 °C to 70 °C unless otherwise noted.Caution Do not operate the NI 9237 in a manner not specified in this document.Product misuse can result in a hazard. You can compromise the safety protectionbuilt into the product if the product is damaged in any way.

CAN and LIN Interfaces for Hi-Speed USBOverviewNI USB-847x devices provide Hi-Speed USB interfaces for Controller Area Network (CAN) and Local Interconnect Network (LIN) monitoring, logging,and testing. With high-speed CAN, low-speed/fault-tolerant CAN, and LIN interfaces featuring optional hardware synchronization, you can use two or more USB-847x devices together to interface to a wide variety of CAN and LIN networks.The USB-847x interfaces are ideal for many types of applications, including:•In-vehicle network monitoring and logging •Bus load monitoring•Device validation with synchronized data acquisition •CAN device development and test•CAN and LIN data correlation with external measurementsThe convenient all-in-one design features a captive 2 m USB cable and built-in transceiver, requiring no extra cables or accessories to get applications running quickly.With hardware timestamping, you can log messages withmicrosecond-accurate timestamps for reconstructing network events and correlating data across synchronized devices. All USB-847xinterfaces use an industry-standard 9-pin male D-Sub (DB9) connector to interface to CAN and LIN buses.Hi-Speed USB connectivity and onboard frame buffering ensure no dropped frames, even under 100 percent bus loads.CAN InterfacesUSB-847x CAN interfaces feature the industry-standard Philips SJA1000CAN controller, which implements ISO 11898 CAN functionality.The SJA1000 offers additional features to aid in system development,including listen-only mode, sleep/wakeup mode, error counter access,and self-reception (echo) mode. USB-847x CAN interfaces recognize standard (11-bit) and extended (29-bit) arbitration IDs and are compatible with J1939 networks.•1-port interfaces for high-speed CAN,low-speed/fault-tolerant CAN, and LIN •Optional hardware synchronization •Hi-Speed USB, bus-powered •500 V digital isolation •Bus error logging•Hardware timestamping – 1 µs resolutionCAN Interfaces•Philips SJA1000 CAN controller•Transmit/receive 100 percent bus load at 1 Mb/s•ISO 11898 compliance for standard (11-bit) and extended (29-bit) arbitration IDs •Software-selectable termination for low-speed/fault-tolerant CAN •J1939 complianceLIN Interfaces•Atmel ATA6620 transceiver•LIN 1.3/2.0 and J2602 compliance •Software-selectable master/slave terminationOperating Systems•Windows Vista/XP/2000Recommended Software•LabVIEW•LabWindows ™/CVI •Visual C++ 6.0•Visual Basic 6.0•Borland C/C++Application Software (included)•CAN/LIN bus monitoring and logging utilityDriver Software (included)•NI-CANNI USB-8472, NI USB-8472s, NI USB-8473, NI USB-8473s, NI USB-8476, NI USB-8476s,Low-speed/fault-tolerant USB-847x CAN interfaces offer software-selectable termination for compatibility with all low-speed network configurations.Onboard Physical LayerThe CAN physical layer connects the CAN controller to the physical bus wires. USB-847x CAN interfaces are available with high-speed and low-speed/fault-tolerant physical layers. All USB-847x devices have onboard physical layer transceivers and require no external dongles. The physical layers are internally powered via a DC-to-DC converter and electrically isolated up to 500 V.LIN InterfacesNI USB-8476 LIN interfaces, featuring the Atmel ATA6620 LINtransceiver, are compliant with the LIN 1.3/2.0 and J2602 specifications and offer software-selectable master/slave termination. The ATA6620features baud rates up to 20 kb/s and offers advanced power management with a low-power sleep mode.Hardware SynchronizationMany automotive applications demand tight integration of CAN, LIN,analog, and digital measurements. In applications such as CAN devicedevelopment and validation, you need to synchronize different measurements to correlate data. You can program this synchronization in software, but OS latency and clock drift between the different onboard oscillators introduce unacceptable delays for certain automotive test applications. NI offers USB-847x CAN and LIN interfaces with an optional hardware synchronization feature, with which the USB interfaces can share timing and triggering signals with other USB-847x interfaces, as well as data acquisition, vision, and motion devices, to achieve true hardwaresynchronization. Determinism is maintained between the trigger signal and the desired response because timing and triggering signals are handled in hardware. The host PC software interacts only to retrieve the data once it is acquired or to write new data.NI-CAN SoftwareNational Instruments provides NI-CAN driver software for Windows Vista/XP/2000. NI-CAN includes a detailed API and examples for NI LabVIEW and LabWindows/CVI, Microsoft Visual C/C++ 6.0 andVisual Basic 6.0, and Borland C/C++. USB-847x interfaces use the NI-CAN Frame API for frame-level access to messages on CAN and LIN networks.The NI-CAN driver software also includes the Bus Monitor and NI Spy utilities to aid in application development.NI-CAN Frame APIThe NI-CAN Frame API offers a powerful interface for accessing NI CAN hardware. The API enables full access to all traffic on CAN and LIN buses.It is a powerful tool for implementing a variety of applications, including CAN and LIN frame-level access, challenge response protocols, remote frame handling, and advanced synchronization.Bus MonitorTo quickly monitor all CAN and LIN bus traffic, use Bus Monitor,a utility that offers an easy-to-use interface that displays all CAN and LIN frames on the network, and log the traffic to disk. Bus Monitor provides options to control, display, and view bus statistics.Figure 2. LIN DB9 Connector (USB LIN Modules)Figure 1.

NI数据采集卡使用入门
NI数据采集卡使用入门NI (National Instruments) 数据采集卡是一种专门用于测量和记录各种类型的电信号、模拟信号和数字信号的硬件设备。
该采集卡被广泛应用于科研实验室、工业自动化和测试测量等领域。
本文将为您介绍如何使用NI数据采集卡进行基本的数据采集和分析。
首先，确保您已经安装了NI数据采集卡及其相关软件。
NI数据采集卡通常需要安装NI-DAQmx驱动软件以及LabVIEW开发环境。
安装完成后，您可以通过电缆将数据采集卡与被测设备连接起来。
接下来，我们需要编写一个简单的数据采集程序。
在LabVIEW中，您可以利用Drag-and-Drop编程的方式轻松构建这样的程序。
首先，打开LabVIEW软件并创建一个新的VI（Virtual Instrument）。
然后，从函数面板中拖放出一个“DAQ Assistant”组件。
在DAQ Assistant界面中，您可以选择数据采集卡的型号，并配置您希望测量的输入通道和参数。
在配置完成后，您需要添加数据保存和分析的功能模块。
您可以从函数面板中选择合适的函数模块，例如“Write to Measurement File”用于保存数据至文件，或者“Signal Processing”模块用于对数据进行处理和分析。
将这些功能模块拖放到主VI中，并根据需求进行参数配置。
在程序编写完成后，您可以通过点击LabVIEW界面中的运行按钮来启动数据采集和分析。
程序会使用预设的配置参数，自动从数据采集卡读取数据，并按照您的设置进行保存和分析。
此外，如果需要对数据进行实时的监测和显示，您可以在LabVIEW界面中添加相应的控件元素。
例如，您可以在Front Panel中添加一个Chart图表控件，用于实时显示采集到的数据。
同样地，您可以从函数面板中选择合适的控制模块，例如“Loop”结构来循环读取数据进行实时显示。
最后，当您完成数据采集和分析后，可以选择将数据保存至文件或者导出至其他软件进行进一步的处理。

Purpose Method of ClearingNONEClearing Notes:User Access:In order to clear the user accessible portion of the PXIe-5603 calibration memory, the user must write a known value to the user string field in the calibration memory. This can be accomplished using the following code excerpt:1 Calibration constants that are stored in device calibration memory include information for the device’s full operating range. Calibration constants do not maintain any unique data for specific configurations in which the device is used unless otherwise specified.2 Items are designated No for the following reason(s): a) Hardware changes or a unique software tool from National Instruments are required to modify contents of the memory listed. b) Hardware modifying software tools are not distributed to public users for any personal access or customization; also known as non-normal use.3 The designation None Available to User indicates that the ability to clear the memory is not available to the user under normal operation. The utilities required to clear the memory are not distributed by National Instruments to customers for normal use.Calibration API:The PXIe-5601 has a user accessible calibration API (Application Programming Interface) for LabVIEW. This API allows the user to perform following calibrations manually, which re-writes the stored calibration constants:1.Downconverter Gain2.LO Export Calibration3.Baseline Calibration Store for Self CalibrationDocumentation for the use of this API is listed in the NI RF Vector Signal Analyzers Help file.If the user performs a manual calibration of this module in a classified location, they may be required to re-calibrate under “default” or “normal” use conditions before the device is cleared for removal from the classified location. These “default” or “normal” use conditions for re-calibration will be defined by the user and the approving declassification group.Self Calibration:The PXIe-5603 also has self calibration capability using the niRFSA Self Cal VI that allows the user to perform a calibration with the currently associated modules. The new calibration constants are stored in the self calibration area in the calibration memory.If the user performs a self calibration of this module in a classified location, they may be required to re-run the self calibration under “default” or “normal” use conditions before the device is cleared for removal from the classified location. These “default” or “normal” use conditions for re-calibration will be defined by the user and the approving declassification group.Terms and DefinitionsUser Accessible User accessible memory allows the user to directly write or modify the contents of the memory during normal instrument operation.System Accessible System accessible memory does not allow the user to access or modify the memory during normal instrument operation, however, may be accessed or modified by background processes. This can be something that is not deliberate by the user and can be a background driver implementation, such as storing application information in RAM to increase speed of use. Under normal use conditions user data is not written to any non-volatile memory locations by the system.Cycle Power The process of completely removing power from the device and its components. This includes a complete shutdown of the PC and/or chassis containing the device; a reboot is not sufficient for the completion of this process.Volatile Memory Volatile memory requires power to maintain the stored information. When power is removed from this memory, its contents are lost.Non-Volatile Non-volatile memory retains its contents when power is removed. This type of memory typically contains calibration or chip configuration information, such as power up states.。

第一章 NI 数据采集卡使用说明书编写人：梅飞一、 安装与配置1. 在安装板卡之前，请首先安装NI-DAQ驱动程序软件。
您可以在随卡附带的光盘内找到这个驱动程序软件。
另外，NI公司的网站上也提供这个驱动程序软件的免费下载：/softlib.nsf/websearch/90B60D5899BCCCDB86256FC700581B 89?opendocument&node=132070_US如果您使用LabVIEW或LabWindows/CVI 等软件来进行编程,需要在安装驱动软件之前先安装开发平台LabVIEW或LabWindows/CVI等软件。
安装过程中，安装程序会提醒您插入DAQ驱动光盘。
2. NI-DAQ驱动软件正确安装后,请关闭计算机,插入数据采集板卡,启动计算机,即可自动找到板卡并安装好，完成整个安装过程。
注意：在安装PCI或者PXI板卡时，一定要将电脑电源关闭；PC机则最好将电源线拔掉，以免电脑主板关机后仍然带电，造成各类损伤。
二、模拟输入说明1. 信号类型根据信号的参考情况， 一个电压源可以分为两类： 接地信号、浮地信号。
接地信号:接地信号是信号的一端直接接地的电压信号。
它的参考点是系统地（例如大地或建筑物的地）。
最常见的接地信号源是通过墙上的电源插座接入建筑物地的设备，例如信号发生器和电源供电设备等。
浮地信号:一个不与任何地（如大地或建筑物的地）连接的电压信号称为浮地信号。
一些常见的浮地信号有电池、热电偶、变压器和隔离放大器。
2． 测量方式按信号连接方式不同可分为三种测量方式：差分(DIFF)；参考单端(RSE)；非参考单端（NRSE）。
注意：NI公司的部分型号数据采集卡不一定完全支持上述三种测量方式，请查询对应数采卡的使用手册。
按测量方式分类可以分为以下两大类测试系统：1）差分测试系统(DIFF)可避免接地回路干扰可避免因环境引起的共模干扰当输入信号有以下情况时，使用差分测试系统：低电平信号（例如小于1V）。

When using these devices, you have complete control of each data point that is updated on the output for each channel. This feature is significant because you can define not only common waveforms such as square, sine, or sawtooth but also complex waveforms. For instance, you are able to create a sine wave that is overlaid with noise in which the amplitude and noise shape are user- defined. In practice, the waveform is defined in a software buffer, within PC memory, and is streamed to the voltage output device using direct memory access (DMA) data transfers. Using DMA transfers,the amount of memory located on board the voltage output device is minimized and swapped with inexpensive PC memory.Real- Time ControlYou can use NI high- speed voltage output devices with the NI LabVIEW Real- Time Module to deliver real- time, deterministic control loop execution. Because they arecompatible with LabVIEW Real- Time, common control algorithms such as PID are simple to implement but, more importantly, you may prototype and implement complex, cutting-edge control algorithms as well. High- performance control, on the order of eight PID loops running in excess of 20 kHz each, is possible with this combination of hardware and software. Each high- speed voltage output device offers multichannel simultaneous updates and hardware- timed single- point updates.Multidevice SynchronizationEach high- speed voltage output device offers the ability to be master or slave of a multidevice timing and triggering system. Use integration technologies such as the RTSI bus,PXI trigger bus, and PFI pins to trigger and synchronize to a wide variety of I/O types. These I/O types range from analog input, image acquisition, motion control, and high- speed digitizers to multifunction data acquisition devices. With these integration infrastructures, you can create powerful, custom test and control systems with ease.Measurement Services SoftwareNational Instruments measurement services software, built around NI-DAQmx driver software, features intuitive application programming interfaces, configuration tools, I/O assistants, and other tools designed to reduce system setup, configuration, and development time. This software,part of your data acquisition purchase, includes helpful features such as:Automatic code generation – The DAQ Assistant is an interactive guide that helps you navigate through configuring, testing, and programming analog output tasks and automatically generates the necessary code for NI LabVIEW, LabWindows/CVI, and Measurement Studio software.Cleaner code development – Basic and advanced software functions have been combined into one easy-to- use yet powerful set to help you build cleaner code and move from basic to advanced applications without replacing functions.High- performance driver engine – NI- DAQmx delivers maximum I/O system throughput with a multithreaded driver.Test panels – With the NI Measurement & Automation Explorer (MAX) configuration utility, you can test all of your module functionality before you begin development.Scaled channels – Easily scale your voltage data into the proper engineering units using the NI- DAQmx measurement- ready virtual channels by choosing from a list of common sensors and signals or creating your own custom scale .LabVIEW integration – All NI-DAQmx functions create the waveform data type, which carries acquired data and timing information directly into more than 400 LabVIEW built-in analysis routines for display of results in engineering units on a graph.NI-DAQmx Base DriverNI-DAQmx Base (available at ) offers Mac OS X and Linux users a programming interface similar to NI- DAQmx.
