Comb Generators
Comb generators produce a wide spectrum of equally spaced spectral lines. The comb frequency is equal to the frequency gap between neighbouring spectral lines. Comb generators are purpose-built “interferers” used to test setups for conducted or radiated emissions. Comb generators for testing radiated emission setups have been characterised in an absorber chamber and can thus be used as a reference source for non-ideal test setups.
