Multifunctional high-integration electromagnetic signal comprehensive detection device and method

Abstract

The invention discloses a multifunctional high-integration electromagnetic signal comprehensive detection device, which comprises an analog part and a digital part, wherein the analog part is used for realizing a measurement channel with multiple measurement functions, the digital part is used for performing data processing on an intermediate frequency signal output by the analog part and displaying a result, the analog part comprises a signal generation channel module, and a broadband signal is generated through a frequency synthesis unit. According to the invention, various measurement channels of the analog part are independent, various measurement functions of the digital part are shared through switch selection, the number of hardware can be greatly reduced, the size is reduced, and the cost is reduced.

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...

Problems solved by technology

[0005] The other is to use independent instruments. Each instrument is carried and used separately, which can be used for independent testing in the field, but the operation is complicated when multiple instruments are required to be used in combination.

[0006] At present, there is also a comprehensive test instrument, which contains multiple different test function modules, but it is large in size and has few functions, which cannot meet the needs of comprehensive testing in the field. There is a large margin, there are problems such as high cost, low efficiency, time-consuming, etc., and the cabinet-type test system is inconvenient to move, and is mainly used for indoor testing; multiple independent instruments need to be used in combination when testing complex parameters. Complicated; comprehensive test equipment simply integrates multiple modular instruments in one chassis, but has a large redundancy, large volume, and inconvenient use
