"Ext DARS" Synchronizes to a digital audio signal.
If the R&S
UPP-B2 option (digital audio interfaces) is installed for the
digital audio interfaces, the synchronization to a digital audio signal is
done either at the asymmetrical "Sync In" BNC jack or on the 9-pin
"DIGITAL BAL" D-Sub connector of the option. The selection is made
in the subsequent "Sync Input" parameter field.
If the R&S
UPP-B4 option (HDMI and digital audio interfaces) is
installed for the digital audio interfaces, the synchronization to a digi-
tal audio signal is done exclusively at the "Sync In" BNC jack of the
option.
The generator runs at the same sampling rate as the supplied signal.
"Ext Clock"
Synchronizes to a clock signal.
The feed of the clock signal depends on the option, see the descrip-
tion under "Ext DARS".
The sampling rate of the generator is determined by the frequency of
the supplied clock signal.
"Ext Inv Clock" Synchronizes to an inverted clock signal.
The feed of the inverted clock signal depends on the option, see the
description under "Ext DARS".
The sampling rate of the generator is determined by the frequency of
the supplied clock signal.

Sync Input
This parameter field appears with the installed R&S UPP-B2 option (digital audio inter-
faces) and determines which socket is used for supplying a synchronization signal
which was selected with the "Sync To" parameter field above.
"Unbal" The supply of the synchronization signal is done in asymmetric mode
at the "SYNC IN" BNC jack of the option.
"Bal" The supply of the synchronization signal is done in symmetric mode
at the 9-pin "DIGITAL BAL" D-Sub connector of the option at the pin
contacts Pin 3 (SYNC IN-) and Pin 7 (SYNC IN+), see
Chapter 5.3.2,
"Interface Assignment" , on page 210.
