3.9 Occupied BW Measurement
The value returned is the estimated turnaround time of each measurement cycle, in
seconds. The turnaround time is the sum of the signal acquisition time, FFT time,
and other overhead time, to complete the entire span of each measurement cycle.
Remote Command
[:SENSe]:<meas>:SWEep:ETIMe?
<meas> is the identifier for the current measurement; any one of CHPower-

Preset Automatically calculated
3.9.9.2 Sweep Config
Accesses controls that let you configure the sweep and control functions of the
instrument, such as "Sweep Time Rules" on page 1324.
Sweep Time Rules
Switches the instrument between normal and accuracy sweep states:
Accy
ACCuracy
Norm
NORMal
Setting Auto Sweep Time to Accy results in slower sweep times, usually about three
times as long, but yields 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. This means that in the Preset state,
instrument amplitude accuracy specifications do not apply.
