The CM 0103M Broadband Current Monitor is designed for measuring alternating currents from 100 Hz to 3 MHz and time‑domain pulse currents.
The CM 0103M Broadband Current Monitor is designed for measuring alternating currents from 100 Hz to 3 MHz and time‑domain pulse currents. It transmits sinusoidal or pulsed signal currents to recording equipment in the form of voltage via electromagnetic coupling, featuring undistorted waveforms and physical isolation from current‑carrying conductors. It meets measurement requirements for sinusoidal signals up to 3 MHz and transient pulse signals with rise times greater than 117 ns as specified in various standards, and is widely used in EMC conducted susceptibility (immunity) tests.
