AH Systems ICP-521 Current Injection Probe, 10 kHz - 100 MHz

The AH Systems ICP-521 high frequency 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 10 kHz - 100 MHz.

The purpose of the test is to determine that RF signals in the range of 10 KHz to 400 MHz, when coupled onto conductors and cable bundles will not cause failure or degradation of their circuit performance. Bundles of wires will be tested with the injection current probes clamped around all wires. If primary power wires utilize the same connector as control and signal lines, they will be included in the test. Every primary power wire will be tested as a single circuit. If they are contained within a bundle, they will be separated and tested. Aircraft flight safety critical equipment will have their wires tested individually for compliance to DO-160.

The A.H. Systems' series of Injection Current Probes offer a wide operating frequency range of 10 kHz to 1000 MHz.  The geometry of the probes optimize coupling to the circuit under test.  Each probe comes with an N-type connector.

Typical specifications requiring the use of current injection probes are:

• IEC 61000-4-6
• Mil-Std 461
• DO-160
• EN-50081-1
• IEC 801-6
• TR-EOP-000063
