遥测匹配器是处在传感器和遥测发射机输入端之间的中间匹配装置,使传感器输出的电讯号能符合遥测发射机输入的要求。一般讲遥测发射机对匹配器有以下的一些要求;1.匹配器输出电压的范围(正负值或全部正值的数值),要符合发射机的输入端的要求。2.发射机输入端对匹配器输出阻抗的要求,要求匹配器输出为低阻抗。3.匹配器输出的信号的性质要符合要求。4.要考虑转换匹配装置的误差要小。5.对被测信号的频率响应要求。可是,在匹配器的设计和研制过程中,有些同志往往是只注重了前面几点,而忽视了最后一点。而最后一点却却是很重要的。不论应用什么遥测系统,频分遥测系统也
A telemetry adapter is an intermediate matching device between the sensor and the input to the telemetry transmitter so that the electrical signals output by the sensor conform to the telemetry transmitter input requirements. In general, telemetry transmitters have some of the following requirements for the matchers: 1. The output voltage range of the matchers (positive or negative or all positive values) to meet the requirements of the transmitter input. 2. Transmitter input impedance matching requirements of the matcher, the matcher output is low impedance. 3. Matching device output signal to meet the requirements of the nature. 4. To consider the conversion error is smaller matching device. 5. The measured signal frequency response requirements. However, during the design and development of matchers, some comrades tend to focus only on the preceding points and neglect the last point. The last point is very important. No matter what telemetry system is used, the frequency division telemetry system also
