(Option P03)
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.
