CG-515 Radiated Comb Generator

Radiated Reference Signal Source for OATS, SAC, and FAC

Broadband EMC reference source for quick verification of radiated emissions test sites between formal calibrations — catches broken cables, blown preamps, and oxidized connectors that could produce months of invalid data.

Wide Frequency Range: 1 MHz to 1.5 GHz

Covers the principal radiated emissions band used by FCC Part 15, CISPR 32 / EN 55032, and most commercial EMC standards in a single instrument.

User-Selectable 1 MHz or 5 MHz Step Size

Choose 1 MHz for maximum spectral resolution near the lower limits, or 5 MHz for faster sweeps and easier identification of individual spectral lines at higher frequencies on the EMI receiver display.

AEMCLRP-Recognized Artifact

Used as a reference artifact for the Automotive EMC Laboratory Recognition Program — supports laboratory-to-laboratory comparison (CISPR 25) and ongoing site validation in vehicle component test labs.

Compact Cubic Chassis

H × W × D: 2.9″ × 3.1″ × 3.1″ (7.4 × 7.9 × 7.9 cm), 0.5 lbs (0.2 kg) — the smallest comb generator in the lineup, easy to position on turntables, calibration jigs, or tripods.

Two Interchangeable Monopole Antennas

3-inch and 12-inch monopoles supplied for optimized radiation across the lower and upper portions of the 1 MHz to 1.5 GHz range.

Battery Operation — 18+ Hours per Charge

Internal 6 V / 1 Ah NiMH battery eliminates external power cables that could disturb the radiated signal, ensuring repeatable measurements. Charger output: 6 VDC (unregulated) at 500 mA.

Automatic Low-Battery Shut-off

Battery monitoring circuit shuts the unit down before output level degrades, preventing invalid reference data being collected with low-amplitude signals and protecting baseline integrity.

Stable, Repeatable RF Output

20 ppm frequency stability, ±0.1 dB amplitude stability, and less than 1 dB time stability over 12 months — ensures that day-to-day baseline comparisons reflect real changes in the test setup, not drift in the source.

External LED Indicators

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

Use as Signal Source for Insertion Loss Measurements

Broadband output also serves as a stable reference for cable, attenuator, and filter insertion loss measurements, as well as chamber-to-chamber comparisons and RF accessory characterization.

NIST-Traceable Calibration

Individually NIST-traceable calibrated; calibration data and certificate ship with each unit. ISO 17025 accredited calibration available on request for laboratories requiring full accreditation chain documentation.

Three-Year Standard Warranty

Three-year standard warranty backed by manufacturer support.
