More Than Standard – Pursuing Precision and Reliability
CST CS114 is an automatic test system for cable‑injection conducted susceptibility testing specifically designed for the GJB 151 series of military standards. It covers the full frequency range from 2 kHz to 400 MHz and is compatible with the GJB 151A, GJB 151B, and GJB 151C standards. The system features a built‑in high‑dynamic‑range power meter, enabling real‑time closed‑loop monitoring and control of test levels – ensuring strict compliance with standard limits and improving repeatability and confidence in test results.
Coverage of GJB 151 Series Military Standards
Strict Compliance with GJB 151C:2024
The system performs cable‑injection conducted susceptibility testing (CS114) in accordance with the GJB 151C standard, and is backward compatible with GJB 151B:2013 and GJB 151A:1997, meeting the standard‑validation needs of military equipment across different program phases.
Closed‑Loop Testing with Real‑Time Monitoring
During testing, the system continuously monitors the injected level on the EUT cable bundle, ensuring it remains within standard limits – safeguarding both test accuracy and equipment safety.
Fully Integrated – Ready to Use Out of the Box
Built‑in signal generator, Class A broadband power amplifier, and power meter, together with PC control software, deliver end‑to‑end automation from calibration to final testing.
Built for High‑Reliability, High‑Efficiency Military Testing
Intelligent Control: Remote control via the PC‑based EMC(CS114) software, integrating parameter setup, test execution, data saving, and report generation into one seamless operation.
