Displayed Average Noise Level
Test Description
The Displayed Average Noise Level is measured within the frequency
range specified. The analyzer input is terminated into either 50 Ω or
75 Ω, depending on analyzer options.
The test tunes the 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.
