a. The maximum InfoBW indicates the maximum operational BW, which depends on the analysis BW
option equipped with the analyzer. However, the demodulation specifications only apply to the BW
indicated in the following sections.
b. Sample rate is set indirectly by the user, with the Span and Channel BW controls (viewed in RF Spec-
trum). The Info BW (also called Demodulation BW) is based on the larger of the two; specifically,
InfoBW = max [Span, Channel BW]. The sample interval is 1/(1.25  Info BW); e.g. if InfoBW = 200
kHz, then sample interval is 4 us. The sample rate is 1.25  InfoBW, or 1.25  max [Span, Channel
BW]. These values are approximate, to estimate memory usage. Exact values can be queried via SCPI
while the application is running.
Demod Time is a user setting. Generally, it should be 3- to 5-times the period of the lowest-frequency
modulating tone.

modulation sidebands from folding, and
by the interference from LO feedthrough.
