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.
