CGC-105 Conducted Comb Generator with Step Sizes of 10 and 50 kHz

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.
• ▸ Lowest-frequency starting point in the lineup: 10 kHz — only Com-Power conducted comb generator that starts at 10 kHz; ideal for verification of MIL-STD-461, automotive (CISPR 25), and CISPR 32/EN 55032 conducted setups that include sub-150-kHz measurements.
• ▸ Frequency range up to 115 MHz — covers the full CISPR 16, CISPR 32, and EN 55032 conducted emissions band (150 kHz to 30 MHz) with margin.
• ▸ User-selectable 10 kHz or 50 kHz step size — choose 10 kHz for high-resolution baseline data near the lower band edge or 50 kHz for sparser, faster sweeps and easier identification of individual harmonics throughout the band.
• ▸ Output levels close to or above CISPR disturbance limits — harmonics are produced at levels that show clearly on EMI receiver displays without requiring sensitivity adjustments, making baseline comparisons straightforward.
• ▸ High output impedance — safe with powered LISNs — high impedance to external line voltage allows the CGC-105 to be used while the LISN is powered, unpowered, or connected to AC mains, eliminating the need to disconnect the EUT power source between checks.
• ▸ Interchangeable output adapter system (CGC-P25A, CGC-P50A, CGC-P100A) — output pin adapters allow direct plug-in to a variety of LISN EUT power port pin configurations.
• ▸ Optional CGC-105P-ADA-CAL and CGC-105P-ADA-USP adapters — support direct calibration-instrument connection (CAL) and AC-receptacle connection (USP) for additional verification scenarios.
• ▸ Long battery life: over 23 hours per charge — the longest-running comb generator in the lineup; internal 6 V / 1 Ah NiMH supports multiple full days of testing without recharging.
• ▸ Stable, repeatable RF output — 20 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 — 6.5 × 2.3 × 2.4″ (165 × 58 × 61 mm), 0.5 lbs (0.22 kg); easy to carry, store, and plug directly into LISN EUT power ports.
• ▸ External LED indicators — battery low and power on LEDs confirm operating status at a glance.
• ▸ 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.
