Introduction

The CST 20150E conducted immunity test system is an integrated automatic test system in accordance with IEC 61000-4-39, IEC 61000-4-6, YY 9706.102, designed for radiated fields in close proximity - immunity test, conducted immunity test, and supporting pulse and sinusoidal injection tests for power supply lines of electric vehicles. Adopting a highly integrated design, it comes with a built-in signal generator, RF power amplifier and RF power meter, greatly reducing setup costs and system complexity. Built-in wide dynamic range power meter ensures real-time and precise monitoring, stable test procedures and reliable measurement results. Output frequency range of the test system is 9 kHz ~ 230 MHz.

The whole test system, centrally controlled by EMC (-4-39) and EMC (-4-6) software (this product requires the software for operation), can improve system scalability and test efficiency. Test results support one-click saving, printing and internal enterprise sharing.
