c. Press Test Sign
als.
d. Select Module Parameters.
e. Select Embedded Audio, and make sure Audio is on.
6. Check that "PPPP PPPP —- —-" is displayed in the upper right area of the
status bar, indicating presence of two groups of embedded audio.
NOTE. If status bar indicates that embedded audio is n ot present, set the number
of groups t
o 2 for the TG2000 module, even if it appears to be set to 2 already.
7. Connect the AES B 1-2 I/O connector to the digital audio analyzer unbalanced
(UNBAL) i
nput using a 75 Ω cable.
8. Set the audio analyzer for measurement of jitter per AES3-1992 (or 1997). To
configur
e the R&S UPL06 Opt B22, B29 for jitter measurement:
a. Press ANLR to display and configure the analyzer screen.
b. Use the up/down arrow keys, keypad, and SELECT button to set the
parameters in the ANALYZER panel as follows:

9. Allow the jitter reading to settle for a few seconds.
10. Check for a typical Jitter Peak absolute reading of less than 3.5 ns over an
interval of at least 5 seconds, and record Pass or Fail in the test record.
