"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 segments
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.
SCPI command:
[:SOURce<hw>]:BB:GRAPhics:TRIGger:SOURce on page 658
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.
SCPI 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 recording
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 band-
width.
"User"
Under "Graphics Sample Rate", the user can determine the resolution
by setting the signal bandwidth for which the display is to be generated.
SCPI command:
[:SOURce<hw>]:BB:GRAPhics:SRATe:MODE on page 657
Graphics Sample Rate
With "Auto" and "Full Bandwidth":
Displays the signal bandwidth for which the display is to be generated.
With "User":
Selects the signal bandwidth for which the display is to be generated. The setting range
moves between the minimum and maximum bandwidth which is possible for the selected
display. The selection is made graphically by moving the pointer.
