Abstract:Introduced constructing the hardware of radiated emission in GTEM Cell automatic test system. E7402 analyzer is used as a measure received machine and 82357A USB/GPIB interface is done as a gate of transferring data. Contrived an automatic test system using LabVIEW as test program development platform.This system can measure the total radiated power of EUT, calculate the radiated field of EUT on OATS. It also enhances test efficiency and precision has better value of application.
