Comb Generators For EMI EMC Testing

As an EMC testing lab, the accuracy of your results is key to your reputation. Maintaining this accuracy requires properly calibrated quality equipment. Comb generators are an important piece of EMC radiated emissions testing equipment - one that can save you time and money by reducing your reliance on full, annual recalibrations of your site and instrumentation.

Comb Generator CGO-501

CGO-501

Com-Power's CGO-501 Comb Generator is a broadband signal source for quick, [pre-test] EMI radiated emissions test site verifications. Its output spans the frequency range of 1 MHz to 1 GHz in 1 MHz steps. The circular shape of its enclosure provides the foundation for a uniform (omnidirectional) radiation pattern.

Comb Generator CGO-505

CGO-505

The  CGO-505 comb generator is similar to CGO-501 except the output is in 5 MHz steps. There are two reasons why you may go to higher step size: (1) the output is usable to at least 1.5 GHz and (2) the energy density is lower in a given frequency bandwidth, which reduces the likelihood of saturation of the receiver.

Comb Generator CG-515

CG-515

The  CG-515 comb generator is used for EMI EMC testing as a reference source for a fast test site verification. It allows user to select 1 or 5 MHz steps. It is our original square version that is specified in many Industry test standards and therefore has retained its original square base.

Comb Generator CGO-515

CGO-515

The CGO-515 comb generator is used as a reference source on EMI-EMC test sites. It is similar to the CG-515 except it has circular base so as to give a uniform radiated reference signal in all directions. EMC test labs use it on a daily basis for quick verification of their test equipment prior to start collecting their radiated emissions test data.

CGO-520

CGO-520

In this series of comb generators used as radiated signal reference sources in most EMC test sites, CGO-520 increases the usable radiated signal to 4.5 GHz providing output in 20 MHz steps. The circular base acting as a ground plane gives uniform omnidirectional radiated output pattern. This is the highest frequency comb generator with removable antenna.

CGO-51000

CGO-51000

The Comb Generator Model CGO-51000 is a broadband microwave reference signal source to quickly verify an EMI EMC radiated emissions test site such as an OATS (open area test site) or an anechoic chamber. Such test greatly improves the reliability of the setup prior to beginning the test. Its output is usable over the frequency span of 1 GHz to 40 GHz. The output is visible in frequency domain in 500 MHz steps. The base of the reference source is circular to provide an omnidirectional pattern uniform over 360 degrees.
