SWEEP
Instrument Functions: P - Z
• The query returns 1 or 0 into the output buffer. 1 is returned when
there is continuous sweeping. 0 is returned when there is only a single
sweep.
When in a measurement, this command does the following:
• When ON at the completion of each trigger cycle, the trigger system
immediately initiates another trigger cycle.
• When OFF, the trigger system remains in an “idle” state until
CONTinuous is set to ON or an :INITiate[:IMMediate] command is
received. On receiving the :INITiate[:IMMediate] command, it will go
through a single trigger cycle, and then return to the “idle” state.
• The query returns 1 or 0 into the output buffer. 1 is returned when
there is continuous triggering. 0 is returned when there is only a single
trigger.
Use the :TRIGger[:SEQuence]:SOURce command to select the trigger
source.
Example: INIT:CONT OFF
4.7.3 Auto Sweep Time
Switches the analyzer between normal and accuracy sweep states. Provides you the ability
to select the rules for the control of sweep time when Sweep Time is set to Auto.SettingAuto
Sweep Time
to Accy will result in slower sweep times, usually about three times as long, but
better amplitude accuracy for CW signals. The instrument specifications only apply when
Sweep Time is set to Auto,andAuto Sweep Time is set to Accy.
Additional amplitude errors occur when
Auto Sweep Time is set to Norm are usually well
under 0.1 dB, though they are not guaranteed. Because of the faster sweep times and still
low errors, Norm is the preferred setting of Auto Sweep Time.Also,whentheAuto All function
is performed,
Auto Sweep Time is set to Norm.
