Com-Power CGC-255 Application

The main application of the CGC series Comb Generators is to quickly verify conducted emissions test setups. These Comb Generators were designed to plug directly into the EUT power socket of the LISN. The conducted noise output level of the Comb Generators are close to or above the CISPR 22 limits as shown on the typical output plot on the back of this page.

Most EMI labs typically calibrate LISNs and other equipment (spectrum analyzers, cables, connectors, etc.) in the conducted emissions test setup at regular intervals. However, test equipment malfunctions may occur between any calibration intervals and may go undetected until the next calibration. In the meantime, these malfunctions may produce erroneous test results. This is unacceptable and can be avoided by using the Comb Generator as a reference noise source. With the Comb Generator, the test engineer will be able to quickly perform verification of the conducted test setup more frequently to assure accurate test results.

Other possible applications of the CGC series Comb Generator could include production evaluation of components, such as cable shields and filters.
