Sink ARC
With the installed R&S UPP-B4 option (HDMI and digital audio interfaces), the audio
return channel of the HDMI analyzer can be supplied either via direct looping of the
audio signal present at the Sink socket or optionally through the SPDIF output of the
digital audio generator.
"Loopback" The supplied audio signal at the Sink socket is returned via the ARC.
"Dig Aud Gen" The signal of the digital audio generator is returned via the ARC.
Remote command:
SOURce:HDMI:SARC

Protocol Generator
The R&S UPP-B2 (digital audio interfaces) and R&S UPP-B4 (HDMI and digital audio
interfaces) options enable you to generate and analyze channel status data in the data
stream of the digital audio interface according to the IEC 60958-3 standard for Con-
sumer Mode and IEC 60958-4 or AES3 for Professional Mode.
Open the control panel for the digital audio protocol generator by means of the Show
button.
Alternatively, this panel can also be opened via the "Menu bar - Instruments - Protocol
Generator".
Bal Ampl
Only with option R&S UPP-B2 (digital audio interfaces).
Used to set the pulse amplitude of the digital audio signal at the BAL output. The con-
figured voltage corresponds to the peak-peak value of the pulse amplitude when the
output is terminated at the rated impedance (110
ohms).
The standard voltage is 4 V
Setting range: 0 V to 8,5 V
This voltage is linked to the setting for the UNBAL amplitude and is always 4 times
higher than this amplitude.
Remote command:
OUTPut:SIGNal:BALanced:LEVel
on page 691
Unbal Ampl
Used to set the pulse amplitude of the digital audio signal at the UNBAL (BNC) output.
The configured voltage corresponds to the peak-peak value of the pulse amplitude
when the output is terminated at the rated impedance (75
ohms).
The standard voltage is 1 V
