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.

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.

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.

The CGO-5100B Comb Generator is the most economical radiated reference signal source for EMI-EMC test sites as RF comb generator as well as microwave comb generator. Its 100 MHz step size and built in antenna makes it a reliable source in the frequency range of 100 MHz to 18 GHz.

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.

The comb generator Model CGC-255E is a broadband signal source for a quick, pre-test conducted emissions test setup verification of any EMI-EMC test laboratory with LISN (Line Impedance Stabilization Network). Its RF output spans the frequency range of 50 kHz to 400 MHz. The step size can be selectable by the user as 50 kHz or 250 kHz steps.

Model CGC-510E Conducted Comb Generator is a broadband RF reference signal source for EMI-EMC conducted emissions test site verifications. It is designed to plug in directly into an LISN and output a reference signal in the frequency range of 100 kHz to 400 MHz with comb spacing of 100 kHz or 500 kHz. The user is provided with a switch to select the desired spacing.
