Description
technical field [0001] The invention relates to the field of electromagnetic compatibility testing, in particular to a hand-held electrostatic generating device. Background technique [0002] When doing the electrostatic discharge immunity test, according to the test bench construction requirements of the laboratory test site, the electrostatic discharge generator is generally placed on the reference ground plate on the ground, and the existing electrostatic discharge generator generally controls the circuit, The high-voltage generation circuit, as well as the keyboard and display for input and output are all concentrated on one host, and only the single function of electrostatic discharge is realized through the electrostatic discharge gun. Every time a test is done, it is necessary to bend down or squat down to set the test parameters on the host, which is very inconvenient to operate. How to more conveniently conduct the electrostatic discharge immunity test and at the s...
