Description

【Technical field】 [0001] The invention relates to the technical field of microwave device switching, in particular to a program-controlled multi-channel microwave device switching device and method. 【Background technique】 [0002] When carrying out RF signal testing, different test parameters often need to convert the signal to be tested into a standard signal that can be identified and analyzed through operations such as attenuation, amplification, and filtering, which is signal conditioning. In a certain RF system test, the tester uses the RF cable as the connecting medium to connect microwave devices such as attenuators, amplifiers, filters, and splitters in series to achieve different test purposes. Due to different test scenarios and various types of signals to be tested, it is often necessary to manually replace microwave devices during testing, which increases the complexity of the test to a certain extent and reduces the reliability and efficiency of the test. [Con...
