The TIME form of this command (below) can be used to determine the time that the
current trace in the spectrogram started, or to select as the display trace the trace
whose start time is closest to the specified time. This time displays on Display Trace
when Trace Selection is set to Time.
Remote Command
:TRACe:DISPlay:VIEW:SPECtrogram:POSition <integer>
:TRACe:DISPlay:VIEW:SPECtrogram:POSition?
Example
:TRAC:DISP:VIEW:SPEC:POS 146
Dependencies Only appears when the Waterfall window is visible, and either the Waterfall or Spectrum window is
selected
If the command is sent at any other time, it is accepted without error, but you will not see the result
until you once again display the Waterfall window
Couplings The input to this parameter can be trace number or trace time
When Spectrogram occupies a window that has half vertical size, only 300traces can be displayed in
the trace window at any one time
Preset Unaffected by Mode Preset, but set to 0 by Restore Mode Defaults. The value is remembered when
you change in or out of Spectrogram View

Start Time
Can be used to determine the time that the current trace in the spectrogram started
or set the display trace to the approximate start time of the entered time.
The selection of the display trace can be by trace number or by trace start time. The
NUMBER form (see "Display Trace" on page 259) can be used to select as the display
trace the trace with the desired number.
Remote Command
:DISPlay:WINDow4:TRACe:TIME <time>
:DISPlay:WINDow4:TRACe:TIME?
Example Set the Waterfall display trace to be at the given start time. If the time is not exact, the approximate
start will be calculated:
:DISP:WIND4:TRAC:TIME 250 ms
Notes Window 4 is the Waterfall window, associated with the Spectrogram
Dependencies Only appears when a Waterfall window is visible, and either that window or its associated window
(Spectrum) is selected
If the command is sent at any other time, it is accepted without error, but you will not see the result
until you once again display the Waterfall window
Preset 0 s
