| Abstract: | 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. |
