Model 8810A Angle Position Indicator (API) 说明书
One optional Reference supplyGENERALThis second generation API, Model 8810A, truly represents a major step forward in synchro to digital conversion technology. The use of an intelligent DSP design eliminates push buttons and allows all programming to be done either via an integrated touch-screen or a mouse interface. In addition, IEEE-488, Ethernet, and USB interfaces have been added to extend remote operation capabilities. The display can be set for one of three display modes; 0-360º, ±180°, or Degrees, Minutes, Seconds. A wide (47 Hz to 20 KHz) frequency range is standard. As an option, a programmable 2.2 VA internal reference supply can be specified.Improved flexibility is provided by two fully independent inputs that can be used to simultaneously read two separate input signals or can be combined to measure multi-speed Synchros or Resolvers. The gear ratio, for the two-speed mode, is programmable from 2:1 to 255:1Built-in phase correction eliminates errors caused by quadrature and harmonics when reference and signal are out of phase by as much as 60°.The 8810A automatically accepts and displays input voltages from 1.0 to 90 V L-L and Reference voltages from 2 to 115 Vrms over a broad frequency range of 47 Hz to 20 KHz.Therefore, one Instrument can handle most known Synchro and Resolver measurement requirements.The 8810A is a direct replacement for all variations of the previously supplied North Atlantic Industries Model 8810. Special versions (P/N = 8810 Sxxxx), contact factory to determine compatibility.Optional Reference: This design can also incorporate a 2.2 VA programmable reference generator that is used for stand alone applications (See P/N)One optional Reference supply(Drop In Replacement for NAI API Model 8810 with significant new features)One optional Reference supply SPECIFICATIONSResolution0.0001°Input Channels 2 separate isolated InputsSignal Inputs Ch.1: Synchro/Resolver programmable. 1-90V L-L auto-rangingCh.2: Synchro/Resolver programmable. 1-90V L-L auto-rangingEach channel measures the Input V L-L, Reference voltage and frequency.Data is displayed on the front panel and also available via various digital outputs.

Pantech Instruments A881 A881 微处理器控制器说明书
Technical CatalogueAUTO MANUAL STATIONSMODEL 881/A881Microprocessor based and fully configurable IntroductionThe revised and updated version of Model 881 of Pantech Instruments is A881.Pantech's Model A881 are Microprocessor based Auto Manual Controllers, and are designed to control and display control parameters. The instrument serves purpose of an A/M Controller along with an indicator with retransmission output. As an A/M controller, the instrument accepts 4-20 mA input from possible sources like DCS and gives at the output in the normal AUTO mode. During the possible breakdown, the control shifts from the AUTO mode to the MANUAL mode, and the user can now control the output 4-20 mA from the control keys provided on the front panel. This transfer is bumpless. Even in case of failure of A/M station, the controller continuos its control in auto mode. The optional auto bias feature of the instrument allows even manual to auto transfer bumpless. The bias is set automatically in manual mode to allow this bumpless transfer and then it can be changed by the same push buttons in auto mode. External feedback signal o/p from the A/M station allows controller to track A/M output in manual mode. The rates of change of output (in manual mode) and bias (in auto mode) are 1% and 10% per sec.. The instrument has a 4 digit display which displays the Output parameters as configured by the user.The instrument also accepts another 4-20 mA input, displays as a 4 digit display as configured by the user, and gives optional 4-20 mA retransmission signal. The instrument provides 24 V DC transmitter power supply to power up mA transmitter in 2 wire or 4 wire connection system.The modules incorporate low drift operational amplifiers and industrial grade components. Burn out of each module ensures a long trouble free operationModel A881 ( formerly 881 )Push Buttons 5 ( Up, Down, A, M, I/O, F )Up, Down, F Up and Down keys used to vary the output in the Manual Mode.

下面将介绍8位施密特触发器芯片的原理、特点和应用。
首先，我们来了解一下施密特触发器的原理。
施密特触发器是基于正反馈的触发器，它的输入信号通过比较阈值电压来改变输出状态。
当输入信号超过高阈值电压时，输出状态切换为高电平，而当输入信号低于低阈值电压时，输出状态切换为低电平。
这种两级比较的方式使得施密特触发器具有更强的抗干扰能力，可以有效地滤除噪声干扰，提高系统的可靠性。
8位施密特触发器芯片则是将8个施密特触发器集成在一个芯片上。
它通常具有8个输入引脚和8个输出引脚，以及一些控制引脚。
这样的配置使得它能够处理8位的数字信号，并对输入信号的变化进行滞后比较，从而得到稳定的输出状态。
