Development of Network Analyzer Sharing System with Multi-User Access

We presented a network analyzer sharing system that allows multiple user to access a single vector network analyzer. The system consists of hardware that is switching module to extend two-port VNA into multiple ports and software that distributes measurement signals eight port. The hardware uses SP4T switches to simplify the system. The software uses an automatic channel switching time setting algorithm to prevent signal distortion or abnormal signals. To validate this system, we conducted an experiment measuring a device under test. Experimental results validate the measurement performance of the sharing system.
