: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.

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.
If the value is set to ONCE, then INITiate[:IMMediate] will sweep once. If the value is set to AVERage and trace averaging is on, then the unit will sweep and average the next X traces, where X is equal to Shift‑5 (Trace) -> Trace A Operations -> # of Averages. If the value is set to AVERage and trace averaging is off, then the unit will sweep once. When averaging is on, the sweep complete bit is set after the Xth sweep is completed. If no argument is specified, then AVERage is sent.
Default Value

Title
Save On Crossing Limit
Description
When set to ON, automatically saves measurement data when the trace crosses a specified limit line. A limit line must be defined before this command can be enabled.
