Spectrogram Parameters
1. Display Trace
Sets the trace index displayed in the trace window in the Spectrogram mode.
You can determine the trace either by the trace number or the trace time. Trace
1 indicates the latest trace. If you select the trace by trace time, select a trace
that is closest to the set time.

2. Trace Selection
Sets the type for the trace to be displayed in the trace window. It can be set to
"Time" or "TNum".
Each trace is associated with a time value that represents the acquisition time.
The formula is as follows: Trace Time = Trace Number x Acquisition Time.
3. Couple Marker Trace
Sets whether to couple the marker to the selected trace. Turn on a marker, and
set Marker Z to n. The available range of n is from 1 to 8,192. Set the Display
Trace number to n. At this time, enable the Trace Couple function. Then, the
marker will stay with the selected Trace n, and changes with it. When you
disable the Trace Couple function, the marker will be fixed to Marker n that is set
when you turn on the marker. Modify the Display Trace number, and the marker
will not change with the trace.
4. Ref Hue
Adjusts the hue at the top of the color bar in the Spectrogram. The color bar in
the Spectrogram is placed next to the waveform display to map the amplitude
and color in the Spectrogram.
