Product Details

The ICP-623 injection current probe is a device used with EMI measuring instruments to induce RF currents in accordance with MIL-STD 461 susceptibility testing. The conductor or cable under test is passed through the probe aperature and becomes a one-turn secondary winding (when injecting), or a one-turn primary (when receiving). This probe provides minimum insertion loss over its frequency of 5 MHz - 1 GHz.

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.
