Design and Implementation of Multi-parameter Test System for Antenna Thermal Vacuum Test

This paper introduces a multi-parameter test system that can be used for antenna thermal vacuum test. The system consists of a one-dimensional rotating platform, signal acquisition, signal transmission and servo control system. The temperature and other signals in the test are carried out through the signal acquisition system. It is collected and transmitted to the master control system via a signal transmission system and connected to a remote computer via Ethernet. The hardware structure, communication protocol and software design of the antenna thermal vacuum test multi-parameter test system are given. Through the test in the vacuum heat environment, the results show that the system has high measurement accuracy and good stability, and can meet the requirements of the antenna thermal test under the condition of vacuum heat environment.
