This subsystem controls the triggering of measurements.
Continuous/Single Sweep
:INITiate:CONTinuous
Description
Sets the sweep to continuous. If the instrument is currently on hold, and if sweep type is set to continuous, then setting to ON restarts the sweep. If the instrument is currently on hold, and if sweep type is set to single, then setting to ON will set the Sweep Type to Continuous and restart the sweep. If the instrument is currently sweeping, then setting a value of OFF or 0 sets the Sweep Type to Single and holds the sweep. The default value is ON. That is, sending :INIT:CONT is equivalent to sending :INIT:CONT ON. The query version of this command returns a 1 if the instrument is set to Continuous and Run, or it returns a 0 if set to Hold.
Sets the sweep to hold. If the instrument is currently sweeping, then setting a value of ON or 1 pauses the sweep. If the instrument is currently not sweeping, and if sweep type is set to continuous, then setting a value of OFF or 0, restarts the sweep. If the instrument is currently not sweeping, and if sweep type is set to single, then setting a value of OFF or 0, triggers a sweep. The query version of the command returns a 1 if the hold command is set, and it returns a 0 if a Run is set.

Trigger Sweep/Measurement
:INITiate[:IMMediate]
Description
Initiates a sweep/measurement. 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 is 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.
If sweep is set to Run, and sweep type is set to Continuous, then sending the :INIT:IMM command restarts the sweep.
If sweep is set to Hold, and sweep type is set to Single, then sending the :INIT:IMM command starts a sweep (instrument is temporarily in Run). After a single sweep is completed, the instrument returns to Hold.
