Comb Generator with output to 40 GHz

Features

• ▸ mmWave radiated reference signal source for OATS, SAC, and FAC — the highest-frequency comb generator in the Com-Power lineup, purpose-built for daily verification of mmWave EMC test sites.
• ▸ 1 GHz to 40 GHz frequency range — covers the 5G FR2 bands (24, 28, 37, 39 GHz), automotive radar, satellite communications, and CISPR 32 / FCC Part 15 emissions testing through 40 GHz.
• ▸ 1 GHz step size — provides fundamental and harmonics every 1 GHz across the full 40 GHz span, giving 40 well-separated reference markers across the microwave / mmWave spectrum.
• ▸ Frequency stability of 25 ppm — tight frequency tolerance ensures the comb teeth stay aligned to receiver bin centers across the full 40 GHz span over weeks of repeated daily checks.
• ▸ Built-in stub antenna with circular chassis ground plane — integral antenna with a protective cover, mounted on a circular chassis that produces a uniform omnidirectional radiation pattern in the horizontal plane.
• ▸ Dual polarization support — can be used in both vertical and horizontal polarizations for comprehensive site verification matching the polarization of the receive antenna.
• ▸ Catches faults missed by annual NSA calibration — at mmWave frequencies, even slight contamination or wear on connectors causes severe degradation; daily checks with the CGO-51000 detect cable, antenna, or preamp faults before invalid data accumulates.
• ▸ Battery operation, 18+ hours per charge — internal 6 V / 1 Ah NiMH battery eliminates external power cabling that could perturb sensitive mmWave radiated fields.
• ▸ Compact circular chassis — 7″ × 1″ (17.8 × 2.5 cm), 2.5 lbs (1.1 kg); ideal for placement on turntables in compact mmWave test ranges.
• ▸ Stable RF output — ±0.1 dB amplitude stability and <1 dB time stability over 12 months allow direct day-to-day baseline comparison even at high frequencies.
• ▸ Automatic low-battery shut-off and LED indicators — battery low and power on LEDs; auto shutdown protects baseline data integrity.
• ▸ 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.
