4-7 :INITiate Subsystem Spectrum Analyzer Commands

4-7 :INITiate Subsystem
This subsystem controls the triggering of measurements.
:INITiate:CONTinuous OFF|ON|0|1
:INITiate:CONTinuous?
Title: Continuous/Single Sweep
Description: Specifies whether the sweep/measurement is triggered continuously. If
the value is set to ON or 1, another sweep/measurement is triggered as
soon as the current one completes. If continuous is set to OFF or 0, the
instrument enters the “idle” state and waits for the
:INITiate[:IMMediate] command or for :INITiate:CONTinuous ON. The
default value is ON. That is, sending :INIT:CONT is equivalent to
sending :INIT:CONT ON. The query version of the command returns a
1 if the instrument is continuously sweeping/measuring and returns a 0
if the instrument is in single sweep/measurement mode. Note that rapid
toggling between ON and OFF is not allowed. The instrument must be
allowed to make a full sweep before toggling can be done.
Parameter: OFF|ON|0|1
Parameter Type: <boolean>
Default Value: ON

:INITiate:HOLD

:INITiate[:IMMediate]
Title: Trigger Sweep/Measurement
Description: Initiates a sweep/measurement. If :INITiate:CONTinuous is set to ON,
this command is ignored. Use this command in combination with
:STATus:OPERation? to synchronize the capture of one complete set of
data. When this command is sent, the “sweep complete” bit of
:STATus:OPERation? is set to 0, indicating that the measurement has
not completed. The data collection is then triggered. The controlling
program can poll :STATus:OPERation? to determine the status. When
the “sweep complete” bit is set to 1, data is ready to be retrieved.
When averaging is on, the sweep complete bit is set after the first sweep
is completed. An :INITiate[:IMMediate] command must be issued for
each additional sweep desired.
