Total Gain
This parameter field can be edited only if "Limit to FS" or "Limit to Max" is deactivated
and permits the overall signal to be leveled. The upper limit is calculated so that the
level of the overall signal cannot exceed 1 FS for digital generators or the maximum
voltage for analog generators.

5.6.14 Lip Sync
Available only with the R&S UPP
‑
K45 option (expanded audio/video measurements).
The Lip Sync generator function is automatically activated if "Video Source" is set to
"Intern" and "Pattern" to "Lip Sync" in the HDMI generator.
The "Lip Sync" generator function generates a sine burst signal of variable frequency,
length, periodicity and amplitude. With the start of the burst signal, the picture content
of the HDMI signal is set to the color of the "Audio Active Pattern" for the duration of
the burst. During the breaks, in which no audio signal is output, the picture information
changes to the "Mute Pattern". This change creates a trigger condition for the analyzer
with which an offset can be measured between picture and sound. The illustration
below shows the association.
