Product Details

The ICP-621 injection current probe is used for specifications that require the injection of large frequency currents into cable bundles and individual wires. It can be used as an injection source as well as a sensitive monitoring probe. The ICP-621 has an input power rating of 100 watts CW for 30 minutes and covers the frequency range of 10 KHz - 100 MHz.

An injection current probe acts as a multiple turn primary and a single turn secondary transformer, when placed around a power line or signal lead. Thus it provides a (nominal) 50ohm load to the susceptibility signal source, while providing a lower susceptibility signal source impedance when placed in series with the cable under test. An injection current probe is characterized by its insertion loss (dB). The insertion loss describes the inefficiency of the clamp relative to direct injection into a 50ohm circuit.
