76 7600REF Reference and Test Signal Generator
The 7600REF reference and test signal
generator is a high-stability standalone 1 RU
unit for providing system timing. It has a
complete set of reference signals, including a
master Genlock reference loop-through input.
It can be used in either master or slave roles.
A powerful feature is timecode generation, as
well as a complete set of reference signals,
allowing for a very compact timing solution.
Reliability is a top feature of the 7600REF with
dual-redundant power supplies and the ability
to interface to the 7620PX changeover unit for
backup.
For versatility, the 7600REF has no less than
five individually timed analog black and burst
reference outputs. In addition, three SDI feeds
provide individual test signals, including full-
field signals where each can be separately
configured. A full set of audio test signals are
provided with analog audio available as well as
unbalanced AES and embedded audio outputs.
The 7600HD option provides for an additional
four Tri-level sync outputs and a full set of HD
test signals.
The timecode generator options allow for a
versatile solution to timecode. Longitudinal and
vertical interval timecode LTC and VITC can be
output.
The 7600REF can act as an NTP server
ensuring IT-based units keep in step with the
broadcast infrastructure. The time generated
can be set from GPS satellites through the
7600GPS option. This makes the 7600REF an
ideal unit for OB operation.
