Abstract:
Radio administration department permits station's building and distributes frequency used by measurement in radio electromagnetic environment. In order to improve the efficiency and accuracy of testing, the automatic measuring system software based on virtual instrumentation technology(VISA and SCPI) has developed at the VB platform, which changes the phase of outputting data just by printing spectrum chart .The system realizes functions of data sampling, transffering and processing in HP E7405A EMC analyzer. It also can establish database files for saving, inquirring, data shareing, exchanging and processing. The spectrum chart of mearsurment result is the same as that of result by manual work.
