Com-Power Comb Generators

Broadband EMC Reference Signal Sources for Site Verification

Verify your EMC test site between formal calibrations with a battery-powered comb generator. Com-Power’s complete lineup covers radiated applications (OATS, SAC, FAC) from 1 MHz to 40 GHz and conducted applications (LISN verification) from 10 kHz to 115 MHz — with 18+ hours of cordless operation, NIST-traceable calibration, and a three-year standard warranty on every model.

How It Works

Two Product Lines for Complete EMC Site Coverage

01

Radiated Comb Generators

Battery-powered broadband reference sources for OATS, SAC, and FAC site verification — covering 1 MHz to 40 GHz with antenna-based designs that verify the complete radiated emissions measurement chain between formal NSA calibrations.

02

Conducted Comb Generators

Handheld reference sources for LISN-based conducted emissions verification — covering 10 kHz to 115 MHz with plug-in LISN interfaces that inject broadband harmonics to verify LISNs, transient limiters, cabling, and EMI receivers.

03

Battery-Powered & NIST-Traceable

All models deliver 18+ hours of cordless operation and ship with NIST-traceable calibration — eliminating power cables that disturb radiated signal patterns and enabling quick pre-test checks without interrupting the test environment.
