Comb Generator for Conducted Reference Source

Features

• ▸ Conducted reference signal source for LISN-based test setups — verifies the entire conducted emissions measurement chain (LISN, cabling, transient limiter, EMI receiver) in minutes between formal calibrations.
• ▸ Frequency range: 100 kHz to 115 MHz — starts just below the 150 kHz CISPR conducted band lower limit; covers FCC Part 15 and CISPR 32 / EN 55032 conducted measurement ranges.
• ▸ User-selectable 100 kHz or 500 kHz step size — choose 100 kHz for higher-resolution baseline data near the band edge or 500 kHz for sparser, faster sweeps and easier identification of individual harmonics throughout the band.
• ▸ Direct plug-in to LISN EUT power port — standard NEMA 15-P type connector plugs directly into the EUT power socket on the LISN; adapters allow connection to other socket types worldwide.
• ▸ High impedance to external line voltage (AC or DC up to 230 V) — the high-impedance design allows the CGC-510E to be used while the LISN is connected to an external power source, eliminating the need to disconnect mains between checks.
• ▸ Simulates an EUT generating conducted EMI noise — replicates real-device operating conditions, allowing verification of the LISN and downstream measurement equipment under realistic loading.
• ▸ Battery operation, 18+ hours per charge — internal 6 V / 1 Ah NiMH battery eliminates external power leads that could couple noise into the conducted measurement.
• ▸ Stable, repeatable RF output — 50 ppm frequency stability, ±0.1 dB amplitude stability, and <1 dB time stability over 12 months allow direct comparison of measurements taken months apart.
• ▸ Compact form factor — 5 × 2.2 × 2.2″ (13.2 × 5.9 × 5.9 cm), 1 lb (0.45 kg); plug-and-go form factor that integrates with the LISN setup without occupying bench space.
• ▸ External LED indicators — battery low and power on LEDs confirm operating status at a glance during routine verification.
• ▸ NIST-traceable calibration — calibration data and certificate ship with each unit; ISO 17025 accredited calibration available on request.
• ▸ Three-year standard warranty — backed by manufacturer support.
