3.5 ACP Measurement
Sweep Time Annotation (Remote Query Only)
Returns the Sweep Time Annotation value. Available only on non-sweeping
hardware.
This value is also displayed in the result trace window.
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-
|ACPower|OBWidth|MONitor
Example Channel Power measurement
:CHP:SWE:ETIMe?
Dependencies Available only on non-sweeping hardware
Preset Automatically calculated
3.5.14.2 Sweep Config
Accesses controls that enable you to configure the Sweep and Control functions of
the instrument.
Sweep Time Rules
Switches the instrument between NORMal and ACCuracy sweep states.
Setting Auto Sweep Time to ACCuracy 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 ACCuracy.
Additional amplitude errors that occur when Auto Sweep Time is set to NORMal are
usually well under 0.1dB, though this is not guaranteed. Because of the faster
sweep times and still low errors, NORMal is the preferred setting of Auto Sweep
Time. Auto Sweep Time is set to NORMal on a Preset. This means that in the Preset
state, instrument amplitude accuracy specifications do not apply.
Remote Command
[:SENSe]:ACPower:SWEep:TIME:AUTO:RULes NORMal | ACCuracy
[:SENSe]:ACPower:SWEep:TIME:AUTO:RULes?
Example
:ACP:SWE:TIME:AUTO:RUL NORM
:ACP:SWE:TIME:AUTO:RUL?
