Com-Power CG-515 Application

The most important application of a Comb Generator is trouble shooting Open Area Test Sites (OATS). An OATS must be completely calibrated before it is put into service. When the validity of the test data taken at an OATS is in doubt after it is put into service, it is not always practical to perform complete site calibration. The Comb Generator is a quick calibration tool that can help identify potential problems with the site. For instance, emission measurements taken from a product at two different test sites can sometimes vary. It is very difficult to determine the cause of the variation. Using the same test setup, measurement can be taken with a Comb Generator in place of the product at both sites. The data can be compared to determine if variation is due to the product or the test site.

Other uses of the Comb Generator include evaluating shielding effectiveness and /or resonance performance of enclosures for electronic equipment. Shielding per­formance of an enclosure can be evaluated simply by comparing the noise with and without an enclosure. The Comb Generator can also be used for production evalu­ation of components, such as cables and filters.
