CGO-520

The CGO-520 is a battery-powered radiated comb generator and broadband EMC reference signal source covering 20 MHz to 4.5 GHz in fixed 20 MHz steps — the highest-frequency comb generator with detachable antennas in the lineup.

Circular base for uniform omnidirectional radiation — the chassis acts as a ground plane producing consistent radiated output regardless of orientation on the turntable.

Two detachable interchangeable monopoles (2-inch and 12-inch) supplied for optimized radiation across the lower- and higher-frequency portions of the 4.5 GHz range.

5G FR1 sub-6 GHz radiated emissions verification — covers the WiFi, Bluetooth, cellular, and FCC Part 15 / CISPR 32 microwave bands relevant to wireless device compliance.

Automotive EMC under CISPR 25 — the extended 4.5 GHz reach covers vehicle wireless module compliance bands for in-vehicle radiated testing.

OATS, SAC, and FAC site validation at frequencies above 1 GHz where traditional comb generators run out of range; quick daily checks catch microwave preamp degradation and high-frequency cable failures.

18+ hours battery operation on internal 6 V / 1 Ah NiMH; battery elimination of external cabling is critical above 1 GHz to prevent radiated pattern disturbance. 20 ppm frequency stability, ±0.1 dB amplitude stability.

Compact pen-style chassis 7″ × 1″ (17.8 × 2.5 cm), 1.5 lbs (0.7 kg). Individually NIST-traceable calibrated; ISO 17025 available on request. Three-year warranty.
