CGO-5100B

The CGO-5100B is a battery-powered microwave comb generator and broadband EMC reference signal source covering 1 GHz to 18 GHz in fixed 100 MHz steps — the most economical microwave radiated reference for EMC test sites.

5 ppm frequency stability — tighter tolerance than lower-band models, critical at microwave frequencies where receiver resolution bandwidths are narrower.

Built-in stub antenna on a circular chassis ground plane produces a uniform omnidirectional radiated reference signal in the horizontal plane — no antenna swap-outs required across the band.

Microwave radiated emissions verification for FCC Part 15, CISPR 32 / EN 55032, MIL-STD-461 RE102 upper band, and RTCA DO-160 radiated; ideal for verifying microwave horn antennas, preamplifiers, and high-frequency cabling.

5G sub-18 GHz site verification — covers 5G FR2 lower bands (24 GHz approach) and most automotive radar pre-compliance testing.

Detects connector and cable issues missed by annual NSA calibration — at microwave frequencies, even slightly oxidized or loose connectors cause dB-level errors; daily checks catch degradation immediately.

Shielding effectiveness measurements on enclosures and materials across the microwave band; place inside the enclosure and measure leakage outside with a horn antenna.

Compact 6″ × 1″ (15.24 × 2.54 cm) circular chassis, 1 lb (0.45 kg); ~18 hours per charge on 3.6 V NiMH battery. NIST-traceable calibration; ISO 17025 available on request. Three-year warranty.
