Automated Measurement System for Wireless Transmitters

摘要：

In this paper, an automated measurement system for wireless transmitters with different frequencies, modulation types, and bit rates is introduced. Using VISA (Virtual Instrument Software Architecture) and COM API (Application Programming Interface), the system can operate the spectrum analyzer, vector signal analyzer (VSA89600), oscilloscope according to the users requirements. With the help of peripheral circuits and multithreaded programming techniques, the automated measurement system can measure from DC to radio frequency signals; perform spectrum and modulation quality analysis of EUT (Equipment under test) automatically; during the measurement process, operating status of EUT can be real time monitored, if the operating status of EUT is abnormal, EUT would be shut down immediately.
