Current monitoring / Sensing probes for CISPR MIL-STD 461 & DO-160

CLCE-1032 RF Current Probe

• Operates over a wide frequency range from 9 kHz to 1000 MHz.

• Fully compliant with CISPR 22/32, MIL-STD-461, and DO-160 test standards.

• Includes individual NIST-traceable calibration with optional ISO 17025.

• Backed by a three-year manufacturer warranty.

Description

• The CLCE-1032 is a split-core RF current probe designed for EMI compliance testing and current monitoring during immunity tests.

• Its hinged, circular enclosure allows quick insertion of cables without disrupting the test setup.

• Works with spectrum analyzers, EMI receivers, or other 50Ω measurement devices to detect and measure RF current via inductive coupling.

• Transfer impedance or admittance conversions help convert voltage to current readings (e.g., [dBuV] - [dBΩ] = [dBuA]).

Application

• Ideal for non-intrusive measurement of RF currents on cables or wire bundles without removing insulation.

• Functions like a toroidal transformer—the cable acts as a single-turn primary, and the probe as the multi-turn secondary.

• Commonly used for conducted emissions measurements in compliance and pre-compliance setups.

Calibration

• Calibration is performed using a 50Ω coaxial calibration fixture for accurate measurement of insertion loss, transfer impedance, and VSWR.

• FCLCE-1032 calibration fixture (optional) ensures standardized calibration.

• Each unit comes with calibration data and a certificate; ISO 17025 calibration is available on request.
