Standard
ANSI S4.40 (AES3)
Output Channels
4 (2 AES/EBU pairs)
Synchronism
The signal timing is derived from the video clock source, either the
internal oven oscillator or the genlock feed. 48kHz signal is related to
video frame as per SMPTE/EBU recommendations.
Grade * see note 1
Meets grade 1 when genlock lock mode = internal or stable 10MHz
reference used.
Clock jitter * see note 1
< 1ns

Grade
Grade bit manually adjustable between grade 1 and grade 2.
User data
User configurable
Other
Both channels may be set to silence. Channels can be swapped.
Note 1. When the unit is locked to a genlock feed, the frequency stability of the AES signal is
dependent on the quality of that feed.
