Test Limits
See test limits in the test result Table 22-14 and Table 22-15 .
Overview
A signal generator is used as the signal source for the test. The source
amplitude is varied using the signal source amplitude control. The attenuation
and resolution bandwidth are varied on the EMI receiver. The source amplitude
is measured by the power meter and receiver at each setting, and the values
compared. The difference between each pair of measurements indicates the
amplitude accuracy.
This measurement is performed for both RF inputs.
