CGO-5100B

Microwave Radiated Reference Source for OATS, SAC, and FAC

Broadband EMC reference for fast pre-test validation of radiated emissions test sites in the microwave bands above 1 GHz — verifies the full measurement chain between formal calibrations.

1 GHz to 18 GHz Frequency Range

Covers FCC Part 15 / CISPR 32 microwave bands, the upper portion of MIL-STD-461 RE102, RTCA DO-160 radiated, and 5G FR2 sub-bands — ideal for verifying microwave horn antennas, preamplifiers, and high-frequency cabling.

100 MHz Step Size — Well-Spaced Reference Markers

Produces fundamentals and harmonics every 100 MHz throughout the 18 GHz span, providing well-separated reference markers across the microwave spectrum for easy identification on spectrum analyzer displays.

5 ppm Frequency Stability

Tighter frequency tolerance than lower-band models — critical at microwave frequencies where receiver resolution bandwidths are typically narrower, ensuring comb teeth stay aligned to bin centers across the full 18 GHz span.

Built-In Stub Antenna with Circular Chassis Ground Plane

Integral antenna mounted on top of a circular chassis produces a uniform omnidirectional radiation pattern in the horizontal plane — no antenna swap-outs required anywhere across the 1–18 GHz band.

Detects Connector and Cable Issues at High Frequencies

At microwave frequencies, even a slightly loose or oxidized connector produces dB-level measurement error. Daily verification with the CGO-5100B catches degradation immediately — before it corrupts compliance data.

Battery Operation — ~18 Hours per Charge

Internal rechargeable 3.6 V NiMH battery eliminates external power cabling — especially critical above 1 GHz where any cable near the radiating antenna could perturb the radiated field. Charging time: 8 to 10 hours.

Compact Circular Chassis

6″ × 1″ (15.24 × 2.54 cm), 1 lb (0.45 kg) — ideal for placing on turntables in 3 m or 10 m chambers without occupying significant setup space.

External LED Indicators

Battery Low and Power On LEDs confirm operating status at a glance during chamber walk-throughs — no need to interrupt a test session to verify the unit is active and sufficiently charged.

Suitable for Shielding Effectiveness Measurements

Broadband output is also useful for evaluating enclosure and material shielding effectiveness across the microwave band — place inside the enclosure and measure leakage outside with a horn antenna.

NIST-Traceable Calibration

Calibration data and certificate ship with each unit. ISO 17025 accredited calibration is available on request for laboratories requiring full accreditation chain documentation.

Three-Year Standard Warranty

Three-year standard warranty backed by manufacturer support.
