The standards RTCA/DO-160 section 20 (Environmental Conditions and Test Procedures for Airborne Equipment Section 20: Radio Frequency Susceptibility (Radiated and Conducted)), MIL-STD-461 (REQUIREMENTS FOR THE CONTROL OF ELECTROMAGNETIC INTERFERENCE CHARACTERISTICS OF SUBSYSTEMS AND EQUIPMENT) and IEC/EN 61000-4-6 (Testing and measurement techniques – Immunity to conducted disturbances, induced by radio-frequency fields) define a method for test level setting in a calibration jig. The PCJ 9201 meets all the requirements and provides additionally a save way for measuring the insertion loss of current sensing probes and monitoring probes. The enhanced VSWR offers measurements in range up to 400 MHz.
