Displayed Average Noise Level (DANL)

Test Limits (with 0 dB input attenuation)
See
The Displayed Average Noise Level (DANL) of the signal analyzer is measured
across a 10 kHz frequency span at several center frequencies. The analyzer
input is terminated into a 50Ω load. A test is performed to assure the
measurement is not performed in the presence of a residual response. The
measurement is then averaged, and the result is normalized to a 1 Hz
bandwidth.
