Com-Power Comb Generator model CGO-51000

The Comb Generator can be used to determine if the test sites are causing variation. Without such a reference source, it would be extremely difficult to compare several sites. It can also be used to check the shielding effectiveness of an enclosure.

The CGO-51000 Comb Generator is a radiated reference signal source. It is a self-contained source of signals consisting of frequency harmonics at 1 GHz intervals, and is usable from 1 GHz to 40 GHz. The signals generated by CGO-51000 are stable and can be used as reference for validating high frequency test setups in open area test site or anechoic chamber.

This Comb Generator has an omni directional built-in antenna, which works in conjunction with the chassis of the unit. The circular chassis of the Comb Generator helps radiate the signal uniformly in all directions in the horizontal plane. The built-in antenna of the CGO-51000 provides improved signal stability, however it cannot provide conducted reference signals.

The CGO-51000 Comb Generator is powered by a rechargeable internal battery pack. The internal power eliminates the need for an external power cable and its effect on the radiated signal pattern or level. When fully charged, the battery allows continuous use of the Comb Generator for up to 18 hours. The Comb Generator and its charger are shipped with a custom wooden storage box.

Radiated emissions measurements for EMC are usually conducted on an Open Area Test site (OATS) or an anechoic chamber. These require periodic calibration to ensure repeatable and accurate EMC measurements.

The Signal Generator is a tool to solve these problems. The test engineer should keep a daily log of a few Comb Generator radiated readings before starting his test. He is able detect potential problems with site by monitoring any change in the readings. For example, any problem or change with antenna, cables, preamplifiers, attenuators or receiver will be reflected in the Comb Generator data with the same setup. The same method can be utilized when EMC emissions measurements for a product varies with sites.
