摘要
用计算机、ＧＰＩＢ接口母线、信号发生器、功率放大器、场强监视器等构成自动测试系统，在“千兆赫横电磁波小室（ＧＴＥＭ）”内产生均匀的横电磁波。电场强度：１－３０Ｖ／ｍ，调幅度：０－９５％，频率范围：２０ＭＨｚ－１０００ＭＨｚ，任意步进扫频。充分满足了ＩＳＯ／ＩＥＣ６１０００－４－３《辐射（射频）电磁场抗扰度试验》等有关标准对试验装置的要求。
An auto-control test system is constructed with a compute, GPIB, a signal generator, a power amplifier, and a field strength monitor, to form even transverse electromagnetic waves in a GTEM. Electric field.strength: 1 - 30V/m,amplitude modulation: 0-95 %,frequency range: 20MHz-1000MHz,Frequency sweeps at any step length. The demands for test device of ISO/ IEC61000 - 4M - 3 (Electromagnetic compatibility Radiated, radio - frequency field immunity) and other relate standards are satisfied sufficiently.
