Absorbing Clamp for up to 1cm diameter cable
- ▸ Absorbing clamp (ferrite clamp), 30 MHz–1 GHz — disturbance power measurement on power and auxiliary I/O cables per CISPR 13 [EN 55013], CISPR 14 [EN 55014], and CISPR 32 [EN 55032].
- ▸ 0.5" (12.7 mm) aperture for cables up to 1 cm (0.39 in) diameter — matched to small mains cords, low-voltage DC leads, and signal/IO cabling from lighting controls, small appliances, and ITE peripherals.
- ▸ CISPR 16-1-3 compliant absorbing clamp measurement method (ACMM) — broadband RF current transformer plus two sets of split-ferrite rings deliver defined RF termination and decouple the mains side.
- ▸ Household appliances and small electronics — kitchen mixers, hair dryers, electric shavers, hand tools, and other small CISPR 14 products with mains cords under 1 cm.
- ▸ Lighting equipment with thin cabling — LED drivers, dimmers, fluorescent ballasts, and similar CISPR 15-style products evaluated using disturbance power on the power cord.
- ▸ ITE and multimedia auxiliary I/O cabling — USB, audio, video, and other peripheral cables on multimedia equipment qualified per CISPR 32 [EN 55032].
- ▸ Rolling chassis with wheels and top handle — clamp slides smoothly along the line under test for the swept length measurement called for in the absorbing clamp method.
- ▸ NIST-traceable individual calibration with three-year warranty — ISO/IEC 17025 accredited calibration optional; pairs naturally with the SPA-900TG series spectrum analyzer/EMI receiver for disturbance power scans.
CLA-050 Features
- ▸ Absorbing clamp (ferrite clamp) per CISPR 16-1-3 — disturbance power measurements for CISPR 13, 14, and 32
- ▸ Frequency range 30 MHz to 1 GHz — covers the full CISPR disturbance power band
- ▸ 0.5" (12.7 mm) aperture diameter — cables up to 1 cm (0.39 in) diameter
- ▸ Clamp factor −4 to +5 dBpW/µV [−17 + clamp insertion loss]
