Introduction

The calibration specification is based on GB/T 17626.2 "Electromagnetic compatibility - Testing and measurement techniques - Electrostatic discharge immunity Tests "and IEC 61000-4-2:2008" Electromagnetic compatibility - Testing and measurement techniques Electrostatic discharge immunity test " (Electromagneticcompatibility (EMC) -Part 4-2. Testingandmeasurementtechniques-Electrostaticdischargeimmunitytest) calibration requirements for ESD simulator compiled.

This specification is the first release.

3 Terms

3.1 holding time Prior to discharge, leaving the test voltage drop due to leakage of not more than 10% of the time interval.

3.2 Transfer impedance transferimpendence ESD target - Attenuator - defined transfer impedance of the cable is injected into the current and the current output target input Voltage precision than 50ohm load (the precise load is placed at one end of the cable, replace the oscilloscope load).

Note. ESD simulator calibration procedure, if the current Isys injected onto the target, then the oscilloscope displays a voltage Vosc. In order to use the current display voltage to calculate the unknown, we need to determine the low-frequency transfer impedance. Low-frequency transfer impedance can pass Determined through the following steps.

- In the front-end electrostatic discharge target injection 1A DC current Isys. The front end of the current target is to discharge that side.

- In the cable end and the connection end of the oscilloscope, connect a 50ohm load precision. 50ohm load tolerance of ± 1%.

- voltage V50 measurement precision 50ohm load.

The transfer impedance. Zsys = V50 Isys
