Abstract

The invention discloses a method for setting the amplitude initial value of a signal source in an electromagnetic radiation sensitivity automatic test, which refers to an antenna factor calculation correlation and the related quantities of a first test frequency point to attain the antenna factor of the radiation antenna at the frequency point; refers to an amplitude initial value reference value of the signal source, the antenna factor of the radiation antenna at the first test frequency point, and the electromagnetic radiation field intensity corresponding to a second test frequency point regulated by test standards, the present gain of a power amplifier, the loss caused by the test cables and test loop of the second test frequency point, to calculate the amplitude initial value reference value of the signal source. Referring to the amplitude value, amplitude can be adjusted finely as the present signal source amplitude initial value. According to same amplitude adjustment schemes, the initial value setting method can effectively improve test efficiency.

Description

technical field

[0001] The invention belongs to the field of electromagnetic compatibility automatic testing, and relates to a method for setting an initial value of signal source amplitude in automatic testing of electromagnetic radiation sensitivity. Background technique

[0002] Electromagnetic radiation susceptibility refers to the strength of the electromagnetic radiation interference field that causes equipment, subsystem or system performance to degrade.

[0003] The purpose of the electromagnetic radiation susceptibility test is to examine the ability of the tested product to withstand the external radiated electromagnetic field. The electromagnetic radiation susceptibility automatic test system is generally composed of a signal source, a power amplifier, a radiation antenna, a field sensor, a monitoring device, and a PC (see figure 1 As shown), the output signal of the signal source is transmitted to the input terminal of the power amplifier through the radio frequ...
