Current Monitor Clamp

T-57

The T-57 Current Monitor Clamp complies with MIL-STD-461H, RTCA DO-160G and GJB151C-2024, and is designed for measuring high-frequency AC current and time-domain pulse current measurement under low-frequency and DC bias. It transfers  AC or pulse signal currents to recording equipment as voltage signals via electromagnetic coupling.

Featuring undistorted waveform and galvanic isolation from the conductor under test, it meets measurement requirements for AC injection signals up to 500 MHz and transient pulse signals with rise time exceeding 0.9 ns. It is widely used in conducted electromagnetic compatibility (EMC) susceptibility (immunity) testing.

Note: Transfer impedance (dBΩ) =S21+34 dBΩ @50 Ω load

> Supports high-frequency AC current measurement under low-frequency or DC bias

> Supports time-domain pulse (rise time >0.9 ns ) current measurement under low frequency or DC bias

> Undistorted waveform, galvanic isolation from the conductor under test
