5.31 Protocol Analysis
R&S UPP-K21 (digital audio protocol) or R&S UPP-K45 (expanded audio/video mea-
surements) option has to be installed to be able to select the protocol analysis in the
digital audio instrument or in the HDMI instrument. The HDMI instrument is option
R&S
UPP-B4. The digital audio instrument is included in options R&S UPP-B4 and
R&S UPP-B2.
The Digital Audio interface can be used not only to analyze the audio data content of
both channels, but also at the same time to decode the channel-status information and
display transmission errors by means of error flags.
5.31.1 Activating and Configuring the Protocol Analysis
The protocol analysis is configured in the Analyzer Function panel. The channel-status
information and error flags are displayed in a separate window known as the Dig Ana-
lyzer Protocol window. This window can be opened via the "Menu bar - Displays - Dig
Analyzer Protocol" from within the Analyzer Config panel or from within the Analyzer
Function panel.
The setting parameters for the protocol analysis appear at the end of the Analyzer
Function panel.
Prot Analysis / Stream Header
For activating the protocol analyzer.
Depending on the selected analyzer instrument "Digital Audio" or "HDMI", the button
for opening the protocol analyzer is offered either with "Prot Analysis" or "Stream
Header".
The term "Stream Header" identifies a subset of audio-relevant information of the
HDMI analyzer. This data structure consists only of the channel status bytes 0 to 4 of a
consumer format according to IEC 60958.
Independent of it, the protocol window that is opening now will always be referred to
with "Dig
Analyzer Protocol" window.
