Com-Power CLCE-400 Current Probe

Frequency Range: 10 kHz - 400 MHz

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.

Com-Power CLCE-400 Current Probe Product Description

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. It's 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, 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 analyser or EMI receiver or any 50Ω impedance measurement equipment, which measure magnitude quantities in terms of true rms voltage. The Transfer Impedance conversion factor, defined as the ratio of secondary voltage to the primary current, is usually expressed in terms of dB over 1Ω, It is used to convert the voltage quantity into a current quantity, expressed in terms of dB over 1 uA. The conversion factor may also be derived from the Transfer Admittance value, expressed in terms of dB over 1 S.

Application

In general, RF current probes are employed to monitor, or measure, the asymmetrical disturbance RF currents on a wire, cable or cable bundle without making direct conductive contact with the source conductor. The current is measured inductively by clamping the probe around the conductor(s) to be tested. No actual contact is made with the conductor(s), and the insulation is left in place. Essentially, a current probe is a torroidal transformer where the conductor(s) act as a single turn primary, and the probe as a multiple turn secondary.
