CISPR, MIL-STD 461, DO-160 The CLCE-400 RF Current Probe is part of Com-Power's extensive line of radio frequency conducted emission/ immunity test equipment and calibration accessories. The CLCE-400 is suitable for compliance measurements required by CISPR 22, CISPR 32, DO-160, MIL-STD-461, etc, as well as for applied current monitoring during conducted immunity tests. Its design incorporates a split-core ferrite in a rugged, circular hinged enclosure; thereby allowing the probe to be opened on one side in order to easily place the wire(s), cable(s) or cable bundle(s) to be tested into the probe window, making the CLCE-400 much more convenient to use than other non-split core probes. The CLCE-400 is designed to be used in conjunction with a spectrum analyzer or EMI receiver or any 50? impedance measurement equipment, which measure magnitude quantities in terms of true rms voltage.
