:INITiate[:IMMediate] ONCE|AVERage
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: ONCE
