SR830数字锁相放大器中文说明书
SR830数字锁相放大器中文说明书锁相放大器是一种对交变信号进行相敏检波的放大器。
它利用和被测信号有相同频率和相位关系的参考信号作为比较基准，只对被测信号本身和那些与参考信号同频（或者倍频）、同相的噪声分量有响应。
因此，能大幅度抑制无用噪声，改善检测信噪比。
此外，锁相放大器有很高的检测灵敏度，信号处理比较简单，是弱光信号检测的一种有效方法。
美国SRS公司的锁相放大器是世界上应用最为广泛的锁相放大器，以较其他锁相放大器更大的精度，更高的稳定性，和更优良的噪声抑制比来测量信号。
更值得推荐的是其价格合理，性价比要比同类产品高。
工作原理图（仅供参考）在众多锁相中SR830是应用最广泛、性价比最高的双相DSP锁相放大器，其采用数字信号处理（DSP）技术，位相稳定性比模拟产品高百倍左右，动态范围高达到100dB；频率范围为0.001Hz到102.4KHz，完全满足一般的光学、电学、磁学等方面的科研。
并且SR830可以自动增益、自动存储、自动调相、自动偏置，这样操作起来更加简单方便。
GPIB和RS232接口可以方便进行外部通讯，进行远程编程控制。
�频率范围1mHZ到102.4kHZ�>100dB的动态保留�稳定性为5ppm/℃模拟�0.01度的相位分辨率�时间常数位10μs到30ks（最大24Db/倍频程衰减速率）�具有自动获取，自动定相，自动存储，自动补偿功能�合成参考光源�GPIB和RS-232两种接口功能特点概述：输入通道SR810和SR830有6nV/√Hz的微分输入噪声，输入阻抗为10M.,最小量程输入电压的灵敏度为2nV。
输入也可以设置成电流测量的模式，其可选的电流增益为106 V/A和108V/A。
单线路滤波器(50Hz或60Hz)和双线路滤波器(100Hz或120Hz)用来消除线路中有关的干涉。
与传统的锁相放大器不同，SR810和SR830在输入端没有跟踪带通滤波器。
在传统锁相放大器中，带通滤波器是用来提高动态存储的，但它同时也引入了噪声、振幅和相位的误差以及漂移。

HMC830LP6GE used as a tunable reference for second HMC830LP6GEUsing the hMC830LP6ge with a tunable reference as shown in Figure 25, it is possible to drastically improve spurious emissions performance across all frequencies. example shown in Figure 21 graph shows that it is possible to have spurious emissions < -100 dBc/hz across all frequencies. For more information about spurious emissions, how they are related to the reference frequency, and how to tune the reference frequency for optimal spurious performance please see the “spurious Performance” section of hittite PLL w/ integraged VCOs Operating guide. note that at very low output frequencies < 100 Mhz, harmonics increase due to small internal aC coupling. applications which are sensitive to harmonics may require external low pass filtering.P L L s w i t h i n t e g r a t e d V C O - s M t25 - 3000 Mhznotes:。

DRV8308中文用户指南
DRV8308中文用户指南1.1外部实验要求以下是必需的：电源-电源应设置为8.5 V至32 V的电压和至少1 a的电流。
更高的电流设置更好，因为它有助于保持稳定的VM电压，加快启动时间，增加了转矩能力。
DRV8308将此板上的峰值电流限制为5 A，因为感测电阻的大小为0.05Ω，V极限电压为0.25 V。
颤振计-当电机旋转时，它在每个霍尔相位上产生一个周期性的波形，也可以选择在FG 线上。
DRV8308 FGSEL寄存器设置用于速度控制回路的输入并传递给FGOUT。
颤振计可以分析FGOUT信号并计算抖动百分比。
这种抖动或边缘定时的变化，是衡量电机速度一致性的一个指标。
右颤振值通常在0.03%到0.5%之间。
抖动的一些原因是：?磁齿槽力。
高止动扭矩的马达在旋转时有更大的速度变化。
非理想电机绕组在时钟频率模式下，未正确调谐DRV8308寄存器设置。
该装置的速度控制回路具有可配置的极点和零频率以及增益值，它们显著影响抖动性能。
一些无刷直流电动机的输出端有一个安装在背面的印刷电路板，带有感应磁阻的板迹天线。
这条FG轨迹被画成一个圆形的方波。
当电机旋转时，轨迹上会产生一个低电平正弦电压。
DRV8308可以使用此信号在FGSEL 设置为10b时检测电机速度。
由于实现通常导致每物理转数约30到60个FG周期，并且每物理转数仅发生3到6个Hall U周期，FG具有提供更快速度反馈的优点，这可以改善抖动性能。
对于缺少FG的电机，将FGSEL设置为00b 以使用HALL U是最好的。
此设置可以实现与FG非常相似的性能。
对于异或，将FGSEL设置为01b通常会产生更糟糕的结果。
频率-电压转换器和示波器-将FGOUT频率转换为模拟电压并将信号发送到示波器是有用的。
这允许观察自旋向上和自旋向下的剖面，以及任何超调。
有些颤振计有一个集成的频率-电压转换器。
计算机-计算机通过USB电缆连接到PCB，图形用户界面控制MSP430G2553微控制器（MCU）。

It is customer‘s soleresponsibility to provide and continuously ensure a secure connection between the product and customer‘s network or any other network (as the case may be) and to establish and maintainappropriate measures (such as but not limited to the installation of firewalls, application ofauthentication measures, encryption of data, installation of antivirus programs, etc.) to protectthe H8303 product, the network, its system and interfaces against any kind of securitybreaches, unauthorized access, interference, intrusion, leakage and/or theft of data orinformation. ABB Ltd and its affiliates are not liable for damages and/or losses related to suchsecurity breaches, unauthorized access, interference, intrusion, leakage and/or theft of data orinformation.Although ABB provides functionality testing on the products and updates that we release, youshould institute your own testing program for any product updates or other major systemupdates (to include but not limited to code changes, configuration file changes, third partysoftware updates or patches, hardware change out, etc.) to ensure that the security measuresthat you have implemented have not been compromised and system functionality in yourenvironment is as expected.10.2Performance and serviceNetwork performanceType ValueEthernet36 Mbps (56,174 packets/s)ARP20 Mbps (31,208 packets/s)ICMP25 Mbps (39,010 packets/s)IP25 Mbps (39,010 packets/sec)Port and servicePort5070UDP To be used by SIP client.7777TCP/UDP To be used for device management8887TCP To be used for firmware update10777TLS Secure channel for device management10.3Deployment guidelineAll devices need to work in security mode by default and. all devices on one system are to besigned by a public CA at commissioning stage; normally the management software acts as CA.It is suggested that compatible mode is only used when the device needs to communicate with previous generation products. In this mode, data transmission between devices is notencrypted, may lead to data leaks and involves a risk of attacks.When user decide to remove the device from system, user shall reset the device to factorysetting in order to remove all the configuration data and sensitive data in the device. This willprevent sensitive data leak.It is recommended to apply "MAC filter" and "Rate limiter" in the switch to prevent DOS attack.10.4UpgradingThe device supports firmware updates via the management software, where a signature file isused to verify the authentication and integrity of the firmware.10.5Backup/restoreNone10.6Malware prevention solutionThe device H8303 is not susceptible to malware, because custom code cannot be executed on the system. The only way to update the software is by firmware upgrading. Only firmwaresigned by ABB can be accepted.10.7Password ruleThe user must change the engineering password when accessing the engineering settings forthe first time. This engineering password must not include increasing or decreasing numbers(e.g. 123456, 654321).
