CGO-501

The CGO-501 is a battery-powered radiated comb generator and broadband EMC signal source covering 1 MHz to 1.5 GHz in fixed 1 MHz steps — the highest-resolution radiated reference in this band.

Pen-style cylindrical chassis — 7″ × 1.2″ (17.8 × 3 cm), 1.5 lbs (0.7 kg) — with two interchangeable monopoles (5-inch and 12-inch) that optimize radiation across the lower and upper bands.

FCC Part 15 / CISPR 32 / EN 55032 radiated emissions verification — covers the full commercial radiated test band; place on the turntable to validate the entire measurement chain in minutes before each compliance test.

OATS, semi-anechoic chamber (SAC), and fully-anechoic chamber (FAC) site checks — quick reference measurements at strategic frequencies catch failing preamps, broken cables, and bad connectors between formal NSA calibrations.

Dense 1 MHz step resolution reveals narrowband anomalies that wider-step generators miss — ideal for industrial, scientific, and medical (ISM) equipment verification under CISPR 11.

Insertion loss measurements on cables, attenuators, filters, and connectors; also useful for inter-site comparisons and chamber correlation studies.

18+ hours battery operation on internal 6 V / 1 Ah NiMH; automatic low-battery shut-off protects data integrity. 20 ppm frequency stability, ±0.1 dB amplitude stability, <1 dB drift over 12 months.

Custom carrying case and charger included; NIST-traceable calibration with certificate. ISO 17025 available on request. Three-year warranty.
