9.
Connect the
AES B 1--2 I/O
connector to the digital audio analyzer
unbalanced (UNBAL) input using a 75
Ω
cable.
10.
Set the audio analyzer for measurement of jitter per AES3--1992 (or 1997).
11.
Allow the jitter reading to settle for a few seconds.
12.
Check for a typical Jitter Peak absolute reading of less than 3.5 ns over an
interval of at least 5 seconds, and record the pass/fail result in the test record.
13.
Move the cable to each of the remaining AES B I/O connectors and repeat
steps 9 through 12 for each AES B I/O connector.
14.
Disconnect the test setup.
This test measures AES level meter accuracy over the audio frequency range.
Typical Operation Check.
This test checks for typical operation. Typical values are
not guaranteed characteristics and are listed in the test record as pass / fail.
