Abstract

The embodiment of the invention discloses a transponder test bench system and test method. A controller controls an arbitrary waveform signal generator to transmit a preset signal to realize reading and writing of a transponder message; a power meter records a power of a signal transmitted by the signal generator; a vector signal analyzer analyzes and decodes an FSK signal or PSK signal that is transmitted by a transponder arranged at a first test bench support and determines a signal power and frequency; a network analyzer can test a frequency-amplitude logarithmic relational graph when the transponder is placed on a second measuring bench support, so that the controller can calculate debugging capacitor reference values of different test circuits of the transponder according to output results of the network analyzer and the vector signal analyzer. The user only needs to move the transponder from one test bench support to another test bench support and the test process can be completed automatically, so that the testing efficiency of the transponder can be improved.

Description

technical field [0001] The present invention relates to the technical field of testing, more specifically, to a transponder testing system and testing method. Background technique [0002] Transponder transmission system is a safety transmission system based on point information transmission, which is installed on the track to realize information transmission between roadside equipment or ground equipment and on-board equipment. As a part of the transponder transmission system, the transponder is in The main function in the system is to send the information stored in the system to the on-board equipment. [0003] During the production process of the transponder, it is necessary to measure some electrical parameters of the transponder, and adjust some key parameters (such as capacitance) in the circuit to make its electrical characteristics meet the requirements of the factory index. The circuits to be tested by the transponder include: energy receiving circuit, PSK signal t...
