:INITiate Subsystem Spectrum Analyzer Commands
6-40 PN: 10580-00306 Rev. E MS20xxC PM
Trigger Sweep/Measurement
:INITiate[:IMMediate]
Description: Initiates a sweep/measurement. If :INITiate:CONTinuous is set to
ON, then 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 is not complete. 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, then data is ready to
be retrieved.
If the value is set to ONCE, then :INITiate[:IMMediate] sweeps
once. If the value is set to AVERage, and if trace averaging is on, then
the instrument sweeps and averages 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 if trace averaging is off, then the instrument
sweeps 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.
