Occupied Bandwidth Measurement
Sweep/Control
Sweep Setup
Accesses the sweep setup settings for the current measurement.
Auto Sweep Time Rules
Switches the analyzer between normal and accuracy sweep states.
Setting Auto Sweep Time to Accy results in slower sweep times, usually about three times as long, but
better amplitude accuracy for CW signals. The instrument amplitude accuracy specifications only apply
when Auto Sweep Time is set to Accy.
Additional amplitude errors which occur when Auto Sweep Time is set to Norm are usually well under
0.1 dB, though this is not guaranteed. Because of the faster sweep times and still low errors, Norm is the
preferred setting of Auto Sweep Time. Auto Sweep Time is set to Norm on a Preset or Auto Couple. This
means that in the Preset or Auto Coupled state, instrument amplitude accuracy specifications do not
apply.
