Current Monitoring Probe
- ▸ CLCE-332 RF current monitoring probe, 9 kHz to 300 MHz — a wideband split-core current probe for conducted emissions measurement and RF current monitoring across commercial, automotive, military, and aerospace EMC testing.
- ▸ Standards-compliant current probe for CISPR, MIL-STD-461, and RTCA DO-160 — meets CISPR 16-1-2 requirements for current monitoring probes and supports conducted emissions and immunity testing per CISPR 22/32, MIL-STD-461, and DO-160.
- ▸ 32 mm (1.26") aperture for standard cables and bundles — fits the most common power cords and cable harnesses encountered in commercial, automotive, and aerospace conducted emissions testing.
- ▸ Nominal 5 Ω transfer impedance (−40 to +15 dBΩ) for accurate conversion — provides reliable RF current-to-voltage conversion across the full operating range with 50 Ω instruments.
- ▸ Robust current handling for stress and immunity testing — rated for 56 A DC, 42 A AC at 400 Hz, 3 A RF continuous, and 1300 A pulse (8/20 µs), well suited to demanding test environments.
- ▸ Hinged split-core design for fast, non-intrusive clamp-on measurement — opens to clamp over installed cables and harnesses without disconnecting connectors, then functions as a toroidal transformer for safe, contactless RF current sensing.
- ▸ Ideal for Bulk Current Injection (BCI) immunity current monitoring — precisely monitors applied RF current during BCI conducted susceptibility testing (such as MIL-STD-461 CS114), validating that injected levels meet test requirements.
- ▸ NIST-traceable individual calibration for accurate, repeatable results — each probe ships with NIST-traceable transfer impedance calibration data; ISO/IEC 17025 accredited calibration available on request, with a three-year warranty.
- ▸ Optimized for use with Com-Power accessories — pairs with the FCLCE-332 Calibration Fixture and the SPA-932TG Spectrum Analyzer for full system compatibility and a complete, standards-compliant RF current measurement setup.
