CGC-255E

The CGC-255E is a battery-powered conducted comb generator and LISN reference signal source covering 50 kHz to 115 MHz — ideal for CISPR 22 / CISPR 32 / EN 55032 Class A and Class B conducted emissions verification.

User-selectable 50 kHz or 250 kHz step size — choose 50 kHz for higher resolution near the band edge or 250 kHz for sparser, faster sweeps with easier harmonic identification.

NEMA 15-P plug connects directly to the LISN EUT power port — standard three-blade interface; international socket types accommodated via adapters.

Simulates an EUT generating conducted EMI noise — replicates real-device operating conditions for verification of LISN impedance, transient limiter, and EMI receiver under realistic loading.

Quick LISN verification before high-stakes testing — plug into each LISN EUT port and confirm baseline within 1 dB at multiple frequencies in minutes; catches LISN drift, cable failures, and connector corrosion immediately.

Production component evaluation — broadband output also useful for spot-checking cable shields, EMI filters, and ferrite suppressors without expensive VNA equipment.

18+ hours battery operation on internal 6 V / 1 Ah NiMH; battery elimination of external power leads prevents noise coupling into the conducted measurement. 50 ppm frequency stability, ±0.1 dB amplitude stability.

Compact 5 × 2.2 × 2.2″ (13.2 × 5.9 × 5.9 cm), 1 lb (0.45 kg). NIST-traceable calibration; ISO 17025 available on request. Three-year warranty.
