This performance verication test must be performed with the EMC analyzer set in the spectrum analyzer mode.
This performance verication test measures the displayed average noise level within the frequency range specied. The EMC analyzer input is terminated in
50.
The test tunes the EMC analyzer frequency across the band, uses the marker to locate the frequency with the highest response, and then reads the average noise in zero span.
To reduce measurement uncertainty due to input attenuator switching and resolution bandwidth switching, a reference level oset is added. The CAL OUT signal is used as the amplitude reference for determining the amount of oset required. The oset is removed at the end of the test by pressing instrument preset.
