Waveguide automated test software for spacecraft thermal test

In the vacuum thermal test of communication satellites, waveguide are often used to establish satellite uplink or downlink communication links. As communication satellites become more and more complex, the use of thermal test waveguide also increases. Before the waveguide is used, the electrical performance of the waveguide needs to be tested. The measurement parameters are mainly standing wave ratio and insertion loss. In order to meet the test work of different types and different frequency bands, and to improve the test efficiency. Based on the LabVIEW integrated development environment, this paper establishes the data communication between the microwave network analyzer and the PC through the LAN interface. Based on the test requirements, the entire test system is designed in layers and modularized, which effectively realizes automatic measurement. Function, improve the test efficiency.
