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.
