The TWCM 00400M Wideband Current Monitor Clamp complies with MIL-STD-461H, RTCA DO-160G and GJB151C-2024, and is designed to measure AC currents from 10 kHz to 400 MHz and time-domain pulse currents.
The TWCM 00400M Wideband Current Monitor Clamp complies with MIL-STD-461H, RTCA DO-160G and GJB151C-2024, and is designed to measure AC currents from 10 kHz to 400 MHz and time-domain pulse currents. It transfers AC or pulse signal currents to recording equipment as voltage signals via electromagnetic coupling.
Featuring undistorted waveforms and galvanic isolation from the conductor under test, it meets the measurement requirements of AC signals up to 400 MHz and transient pulse signals with rise times greater than 0.9 ns. It is widely used in conducted electromagnetic compatibility (EMC) susceptibility (immunity) testing.
