"Expand Only (Coarse/Fine)"
Auto scale is activated. Automatically selects the appropriate scaling
of the y-axis so that the trace is always visible. The range is expan-
ded when a value is out of the right or the left end-of-scale value. The
step width is 5 dB for selection "Exp. (Coarse)" and variable in the
range of 0.2 db to 5 dB for selection "Exp. (Fine)".
"Float (Coarse/Fine)"
Auto scale is activated, that means this parameter automatically
selects the appropriate scaling of the y-axis so that the trace is
always visible. The range is either expanded, when a value is out of
the right/left end-of-scale value or it is reduced when the trace fits into
a smaller scale area. The step width is 5 dB for selection "Flt.
(Coarse)" and variable in the range of 0.2 db to 5 dB for selection "Flt.
(Fine)".

Reset Auto Scale - Power Analysis
Resets the scaling of the y-axis to suitable values after the use of auto scaling in the
expanding mode. For this mode, the Y scale can get too expanded because of tempo-
rary high-power values. The reset function resets the diagram again, to indicate
smaller power values.

Show Grid - Power Analysis
Activates the indication of a grid in the diagram area.
Remote command:
:DISPlay[:WINDow][:POWer]:SWEep:GRID:STATe on page 501
Background Color - Power Analysis
Sets the background color of the diagram to black or white. The background color is
also effective for the hardcopy of the diagram.

Configure time mode settings
The time measurement mode enables you to analyze internally generated or externally
supplied signals. I time mode, the measurement requires an additional trigger event,
with selectable level, hysteresis and drop time. In time domain, you can also analyze
measured pulse data.
