Abstract

The invention discloses a multichannel microwave receiving assembly inter-channel isolation index testing device and method, and the device comprises an excitation signal source and a power detection module. The excitation signal source is connected to the input end of a multichannel microwave receiving assembly through a first switching network. The power detection module is connected to the output end of the multichannel microwave receiving assembly through second first switching network. The first and second switching networks are respectively connected with a controller. When a multichannel microwave receiving assembly inter-channel isolation index is tested, the controller outputs a signal for controlling the switching of the first and second switching networks, enables the power detection module to test the output power value of one channel of the multichannel microwave receiving assembly and the leakage output power values of other channels relative to the channel, carries out the subtraction of the output power value and the leakage output power values, and obtains the inter-channel isolation index of the channel and other channels.

Description

technical field [0001] The invention belongs to the field of electronic equipment testing, and in particular relates to a multi-channel microwave receiving component circuit isolation index testing device and method. Background technique [0002] When testing the isolation indicators of multi-channel microwave receiving components, every time one channel is tested, the other channels need to be connected to the load first, so as to avoid the influence of other channels on the test channel due to impedance mismatch, resulting in abnormal test channel indicators. Therefore, when testing the isolation between channels of multi-channel microwave receiving components, the process is relatively complicated and cumbersome, and a new testing method and device need to be adopted. [0003] At present, manual testing is generally used to test the channel-to-channel isolation of multi-channel microwave receiving components. Test instruments are connected to test channels, and loads are ...
