Comparison device for CS114 project

Abstract

The invention discloses a comparison device for a CS114 project. The comparison device is provided with a signal detection end used for being connected with a signal input end of a frequency spectrograph, a grounding end used for being connected with a grounding system of test equipment, a power input end used for being connected with a power supply of the test equipment, and a power output end used for being connected with a power supply of the test equipment. The comparison device comprises at least four band elimination filters connected in parallel and a non-inductive load, wherein the signal detection end is connected with the power supply input end and the input end of the band elimination filter; the first output end of the band elimination filter is connected with the grounding end; the second output end of the band elimination filter is connected with the first end of the non-inductive load; and the second end of the non-inductive load is connected with the power supply outputend, so that the problem that the difference of CS114 project test results is caused by the fact that the difference of test equipment between laboratories cannot be evaluated in the prior art can beeffectively solved, and the test capability and accuracy of the test equipment can be effectively evaluated.

Description

technical field [0001] The invention relates to the technical field of CS114 items, in particular to a comparison device for CS114 items. Background technique [0002] Electromagnetic compatibility is an important performance index of weapons and equipment, and it is one of the basis for the finalization of weapons and equipment. Electronic information technology has been widely used in the military, and the degree of informatization of weapons and equipment is getting higher and higher, making the electromagnetic environment faced by weapons and equipment increasingly complex. Electromagnetic compatibility issues such as electromagnetic interference and electromagnetic damage have become increasingly prominent. [0003] Project CS114 4kHz~400MHz cable bundle injection conduction sensitivity is a routine item in the standard and is applicable to all military equipment and subsystems, such as "surface ships, submarines, army aircraft, naval aircraft, air force aircraft, space...
