基于在系统可编程模拟电路的遥测接口

Telemetry Interface Based on "In System Programmability Programmable Analog Circuits"

针对军用遥测领域中,被测参量的多样化导致遥测接口电路设计无法进行单元化的问题,提出采用在系统可编程模拟电路(ispPAC)的遥测接口电路。通过对与差分信号源、单端信号源及交流信号输入接口等不同类型ispPAC器件接口电路的分析,说明可以将原先的直接针对遥测接口单元的设计转化为针对ispPAC器件的接口单元设计,为遥测接口电路的单元集成化提供了便利。

For the problem that the parameters being tested are so variable that there is no way to unitize the telemetry interface circuit, it is proposed to use telemetry interface based on ＂In System Programmability Programmable Analog Circuits＂ （ispPAC）. All kinds of ispPAC interface circuit design are analyzed such as the circuit of interface with differential signal source, with single-point signal source and with alternating signal source. The analysis shows that the existing design for telemetry interface unit can be used for ispPAC interface unit. The ispPAC interface is easy to be integrated, providing advantage for the unitization of the telemetry interface circuit.
