5 Command Reference
Initiate Subsystem
The INITiate subsystem is used to control the initiation of the spectrum
analyzer sweep operation.
Continuous or Single Sweep
:INITiate:CONTinuous OFF|ON|0|1
:INITiate:CONTinuous?
Selects whether the sweep operation is continuously initiated or not.
This command affects sweep if not in a measurement, and affects trigger
when in a measurement. This corresponds to continuous sweep or single
sweep operation when not in a measurement, and continuous
measurement or single measurement operation when in a measurement.
When not in a measurement, this command does the following:
• When ON at the completion of each sweep cycle, the sweep system
immediately initiates another sweep cycle.
• When OFF, the sweep system remains in an “idle” state until
CONTinuous is ON or :INITiate[:IMMediate] is
received. On receiving the :INITiate[:IMMediate]
command, it will go through a single sweep 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 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 ON or :INITiate[:IMMediate] 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 in
a continuous measurement state. 0 is returned when there is only a
single measurement.
