Broadband RF Monitor Probe
- ▸ CLCE-252 RF current monitoring probe, 9 kHz to 230 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.
- ▸ Large 52 mm (2") aperture for thick cable bundles and harnesses — the generous window measures multi-conductor power harnesses and shielded cable assemblies where splitting the bundle is not practical.
- ▸ Nominal 0.25 Ω (−12 dBΩ) transfer impedance for reliable signal data — delivers accurate current-to-voltage conversion for compliance-grade conducted emissions measurements.
- ▸ High current handling for heavy-duty testing — rated for 150 A DC, 90 A AC at 50/60 Hz, 72 A AC at 400 Hz, 3 A RF, and 3500 A pulse (8/20 µs), supporting demanding industrial and military setups.
- ▸ 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-452 Calibration Fixture and the SPA-932TG Spectrum Analyzer for full system compatibility and a complete, standards-compliant RF current measurement setup.
