RF Current Sensing Probe
- ▸ CLCE-438 RF current monitoring probe, 9 kHz to 400 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.
- ▸ Medium 38 mm (1.49") aperture for moderate-gauge harnesses — accommodates medium-diameter automotive, industrial, and defense cable bundles that exceed the reach of 27 mm and 32 mm probes.
- ▸ Extended 400 MHz upper frequency for broadband coverage — the wider bandwidth supports applications above the typical CE102/DO-160 range, making it a versatile multi-standard current probe.
- ▸ Nominal 5 Ω transfer impedance (−40 to +15 dBΩ) — ensures accurate RF current-to-voltage conversion with minimal loss for repeatable emissions and immunity measurements.
- ▸ 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-438 Calibration Fixture and the SPA-932TG Spectrum Analyzer for full system compatibility and a complete, standards-compliant RF current measurement setup.
