a
a. DANL for zero span and swept is normalized in two ways and for two reasons. DANL is measured in a 
1 kHz RBW and normalized to the narrowest available RBW, because the noise figure does not depend 
on RBW and 1 kHz measurements are faster. The second normalization is that DANL is measured with 
10 dB input attenuation and normalized to the 0 dB input attenuation case, because that makes DANL 
and third order intermodulation test conditions congruent, allowing accurate dynamic range estimation 
for the analyzer.
