:TRACe:DISPlay:VIEW:SPECtrogram:TIME? can be used to retrieve the time
that the current trace in the spectrogram started.
Markers in Spectrogram
In Spectrogram View, you can put markers on any trace in the Waterfall window. To
put a marker on a particular trace in the Waterfall window, set Display Trace to the
trace upon which you want the marker, then position the marker as desired on Trace
1 in the trace window. When you turn a marker on, or do any kind of Peak Search, if
the marker is a Trace 1 Marker, it appears on the current Display Trace. Then when
you move the Display Trace to other traces in the Waterfall window, the marker
stays on the Waterfall trace it is on.
Markers are displayed in the Waterfall window as little crosses, with one bar sitting
on the trace in question and the other bar perpendicular to it. The selected marker’s
cross is green; the others are white.
You can right-click or touch-and-hold on the spectrogram to get a menu of
functions including:
–
Peak Search
–
Peak Search all Traces
–
Move Marker n here (n=whichever marker is selected)
–
Add Marker Here
There are also two useful functions in the Marker -> menu:
–
Move Marker -> Display Trace
–
Move Display Trace -> Marker
Example
Set Display Trace to spectrogram trace number 125. Turn on Marker 1. Marker 1
appears on Trace 1, which is spectrogram trace number 125. A green diamond
appears on trace 1 in the trace window, and a little cross appears on spectrogram
trace number 125 in the Waterfall window. Now set Display Trace to 200. The trace
window now shows spectrogram trace number 200; Marker 1 disappears from that
window because it is still on spectrogram trace number 125. You can still see the
little cross sitting on spectrogram trace number 125 in the Waterfall window.
The selected marker displays in the upper right corner of the top window display, as
always. If a Delta marker is referenced to a marker on another Spectrogram Trace,
then when the Marker X-Axis Scale is Time, you see the delta that represents the Y-
axis delta between the two markers, as always; but in this case the X-axis delta now
includes the time between the two traces.
