If the setting "Fix marker delay to dynamic range" is enabled, the setting range is restricted
to the dynamic range. In this range the delay of the marker signals can be set without
restarting the marker and signal.
The allocation of marker signals to the outputs is described in the section chapter 5.8.2.8,
"Marker Output Signals", on page 337.
SCPI command:
[:SOURce<hw>]:BB:DM:TRIGger:OUTPut<ch>:DELay on page 629
Current Range without Recalculation - Digital Modulation
Displays the dynamic range within which the delay of the marker signals can be set with-
out restarting the marker and signal.
The delay can be defined by moving the setting mark.
SCPI command:
[:SOURce<hw>]:BB:DM:TRIGger:OUTPut<ch>:DELay:MAXimum on page 630
[:SOURce<hw>]:BB:DM:TRIGger:OUTPut<ch>:DELay:MINimum on page 630
Fix marker delay to current range - Digital Modulation
Restricts the marker delay setting range to the dynamic range. In this range the delay
can be set without restarting the marker and signal.
SCPI command:
[:SOURce<hw>]:BB:DM:TRIGger:OUTPut:DELay:FIXed on page 629
Clock Settings
The clock source is selected in the Clock Settings section.
Clock Source - Digital Modulation
Selects the clock source (also see section "Clock Signals", page 2).
"Internal"
The internal clock reference is used.
"External"
The external clock reference is fed in as the symbol clock or a multiple
thereof via the CLOCK connector.
The chip rate must be correctly set to an accuracy of (± 2% (see data
sheet).
The polarity of the clock input can be changed with the aid of "Global
Trigger/Clock/External Input "Settings.
In the case of two-path instruments, this selection applies to path A.
SCPI command:
[:SOURce<hw>]:BB:DM:CLOCk:SOURce on page 626
Clock Mode - Digital Modulation
Enters the type of externally supplied clock.
"Symbol"
A symbol clock is supplied via the CLOCK connector.
