| Abstract: | As the key subsystem of the space environment simulator, a measurement system of 1000 channels based on Keithley 2750 digital multimeter is introduced in the vacuum thermal test. The system structure and communication, the selection of multiplexer modules, the design of the input junction box, a parallel method for fast measurement, and the configuration of DMM are described in this paper. It is shown that the system works reliably. |
