Remote command:
[:SOURce<hw>]:BB:GRAPhics:MODE
Trigger Source
Defines the trigger for the starting time of the graphic recording.
"Software"
Recording of signals is started automatically in specified intervals.
This asynchronous method is appropriate when a representative dis-
play of the complete signal is desired, as recording starts in a random
time reference to the signal.
"Marker 1"
The starting point for recording signals is determined by marker 1 in
the menu of the active standard.
This synchronous method is appropriate when specific signal seg-
ments are to be shown in greater detail. With periodic signals, a static
image is obtained by selecting a period length of marker 1 that is
equal to the signal period.
The displayed signal segment can be shifted as needed by entering a
marker delay in the Trigger/Marker menu of the active standard.
Remote command:
[:SOURce<hw>]:BB:GRAPhics:TRIGger:SOURce
Scrambling Code
(only if Code Domain (3GPP FDD DL) is selected)
Sets the scrambling code if the "Code Domain" display is selected. Since it is possible
to select a different scrambling code in the menu for each of the 4 base stations and it
is also possible to display an external signal, the scrambling code for which the display
is to be generated must be explicitly specified here.
Remote command:
n.a.
Sample Rate Mode
Sets how the time resolution of the signal is determined. Maximum resolution corre-
sponds to a display covering the entire signal bandwidth. The higher the resolution is,
the shorter the length of the displayed signal segment will be for the specified record-
ing depth.
"Auto"
The resolution is set to an optimum value on the basis of the signal
and display type.
"Full Band-
width"
The resolution is set such that the display covers the entire signal
bandwidth.
"User"
Under "Graphics Sample Rate", the user can determine the resolution
by setting the signal bandwidth for which the display is to be gener-
ated.
Remote command:
[:SOURce<hw>]:BB:GRAPhics:SRATe:MODE
Graphics Sample Rate
With "Auto" and "Full Bandwidth":
Displays the signal bandwidth for which the display is to be generated.
