RF Conducted Immunity Test System CST

Description

The CST 10 series adopt all-in-one design, which integrate signal generator, RF power amplifier and RF power meter and each of them can be used independently. External power amplifier is optional as well as. Test electrical level required by standard can be obtained through driving coupling/decoupling network (CDN), electromagnetic clamp (EM-Clamp) and current clamp by internal wideband power amplifier (class A). The CST 10 series is controlled by PC software, so calibration and test can be conducted automatically, which greatly improves the test efficiency and system extendibility. The generated test result can be saved, printed or shared internally.

Features：

Integrate signal generator, RF power amplifier and RF power meter into one;
Support bulk current injection; optional current monitoring probe; support closed-loop test method;
The creation of test templates makes software operation easy;
USB interface for PC remote control;
