Time Domain Zoom
Using the time domain zoom, the demodulated data for a particular time span is extrac-
ted and displayed in more detail. This is useful if the measurement time is very large
and thus each sweep point represents a large time span. The time domain zoom func-
tion distributes the available sweep points only amoung the time span defined by the
zoom area length. The time span displayed per division of the diagram is decreased.
Thus, the display of the extracted time span becomes more precise. Note that the time
domain zoom area affects not only the diagram display, but the entire evaluation for
the current window.
This function is only available for evaluations in the time domain.
Tip: In addition to the Time Domain Zoom, a graphical zoom is available for all dia-
gram evaluations. However, the graphical zoom is useful only if more measured values
than trace points are available. The (time) span represented by each measurement
point remains the same. For details see chapter 6.8, "Zoom Functions", on page 153.
State ← Time Domain Zoom
Activates or deactivates the time domain zoom mode.
"ON"
Activates the time domain zoom.
"OFF"
Deactivates the time domain zoom and restores the original display. If
more measured values than measurement points are available, sev-
eral measured values are combined in one measurement point
according to the method of the selected trace detector.
Remote command:
[SENSe:]ADEMod<n>:ZOOM[:STATe] on page 258
Start ← Time Domain Zoom
Defines the start time for the time domain zoom area. For spectrum evaluations the
start time is always 0.
Remote command:
[SENSe:]ADEMod<n>:ZOOM:STARt on page 257
Length ← Time Domain Zoom
Defines the length of the time domain zoom area. Enter the length as a time value
manually, or use the "Auto" setting to set the length to the current number of sweep
points automatically.
Remote command:
[SENSe:]ADEMod<n>:ZOOM:LENGth on page 257
[SENSe:]ADEMod<n>:ZOOM:LENGth:MODE on page 257
Time per Division ← Time Domain Zoom
The "Time per Division" softkey in the main Analog Demodulation menu enables the
"Time Domain Zoom" function and defines the zoom area length in one step. The width
of the zoom display is divided into 10 divisions; thus, by entering the time that is dis-
played in each division, you indirectly define the zoom area length ("Time per Division"
* 10). The starting point of the zoom area is determined automatically. To specify the
starting point manually, use the Start setting.
