Problems solved by technology
[0002] In the temperature experiment, it is necessary to repeatedly verify the signal quality (including signal power, signal spurs, and signal phase noise), signal synchronization, and software and hardware design stability of the signal generation board; the analysis of the analog signal requires testers to use multiple Each device is manually operated separately, requiring testers to have high analysis ability and instrument operation experience; the design stability evaluation of the signal generation board needs to be tested repeatedly in each temperature range, which will take up a lot of time for the testers; multi-channel analog signals The synchronous verification often needs to reach the joint debugging of the whole machine to be verified. The iterative modification work needs to be verified by high and low temperature experiments each time, and synchronous verification for the board level is required.

The invention belongs to the technical field of automatic testing, and relates to a temperature experiment automatic testing method and device for a signal generation board. The method comprises the following steps: receiving temperature parameters set by a user so as to regulate and control a temperature control device, and enabling a to-be-tested signal generation board to be in a set temperature range based on the temperature control device; receiving a radio frequency signal generated by the to-be-tested signal generation board; and analyzing the radio frequency signal, including comparingthe signal quality of a specified frequency spectrum region with a set threshold. According to the application, the generated analog signals can be automatically tested according to the requirementsof testers, and the system has the functions of automatically switching on and off the signal generation board, automatically counting the signal quality, automatically counting the synchronization problem frequency, automatically adjusting the temperature range and automatically storing problem signal data; the test steps can be simplified, and the work intensity of testers and the professional operation capability requirements on instruments can be reduced.
