ABSTRACT
The telemetry module testing system, based on virtual instrument technology and FPGA, is a
special automatic testing system designing for measing and testing the telemetry module. Mainly
testing function modules include: the part of transmission coefficient calculation, the part of interface
input impedance calculation, the part of simulated some kinds of bus protocol signals and analog
signals, the analysis of modulated signal. It can greatly improve the efficiency and accuracy.
In this thesis, the design and development process of the telemetry module testing system is
introduced in detail. First of all, some basic knowledge about virtual instrument technology are
analyzed, and then a design scheme based on virtual instrument technology from current available
solutions is put forward and that, the paper discusses the hardware design of the testing
system in detail, including the position, the partmentalization. Besides, the
paper analyzes the work flow of each moudule for the software of the testing system, then explains
and realizes the testing functional modules on the platform of LabVIEW . Finally, the paper
describes the debugging, calibration of the testing system and the problems encountering as well
