Description

technical field [0001] The invention relates to the technical field of electromagnetic signal detection, in particular to a multifunctional and highly integrated electromagnetic signal comprehensive detection device and method. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] Due to the complex composition of radar equipment, there are many electromagnetic parameters that need to be measured during maintenance, involving frequency, power, voltage, waveform and other measurements. Test instruments such as signal sources, spectrum analyzers, power meters, oscilloscopes, and multimeters are required. Currently, There are two main methods for radar equipment maintenance. [0004] One is to use signal sources, spectrum analyzers, power meters, oscilloscopes, and various test instruments to build a test system. It adopts a cabinet structure. Bec...
