Fix marker delay to current range
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:ARB:TRIGger:OUTPut:DELay:FIXed on page 586
Clock Settings
The "Clock Settings" is used to set the clock source and a delay if required.
Clock Source
Selects the clock source.
"Internal"
The internal clock reference is used to generate the symbol clock.
"External"
The external clock reference is fed in as the symbol clock or multiple
thereof via the CLOCK connector.
The symbol 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 Settings".
In the case of two-path instruments this selection applies to path A.
SCPI command:
[:SOURce<hw>]:BB:ARB:CLOCk:SOURce on page 583
Clock Mode
Enters the type of externally supplied clock.
"Sample"
A sample clock is supplied via the CLOCK connector.
"Multiple Sam-
ple"
A multiple of the sample clock is supplied via the CLOCK connector; the
sample clock is derived internally from this.
The "Multiplier" window provided allows the multiplication factor to be
entered.
SCPI command:
[:SOURce<hw>]:BB:ARB:CLOCk:MODE on page 582
Sample Clock Multiplier
Enters the multiplication factor for clock type "Multiple".
SCPI command:
[:SOURce<hw>]:BB:ARB:CLOCk:MULTiplier on page 583
Measured External Clock
Indicates the measured frequency of the external clock signal. This enables the user to
permanently monitor the frequency of the externally introduced clock.
This information is displayed only if the external clock source has been selected.
SCPI command:
:CLOC:INP:FREQ?
