SETUP STATUS
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.
Key Features
High-stability reference generator for •
system master or local slave roles
Sophisticated timecode generator option •
for a complete compact timing solution
Five individually timed analog black/burst •
outputs
Four Tri-level sync outputs with 7600HD •
option – all co-timed with one selectable
Black Burst output of the same frame rate
High stability outputs (0.5 Hz accuracy) •
Redundant power supplies standard •
Can be used with 7620PX changeover for •
fully redundant operation
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 fullfield 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.
Simultaneous multi-standard outputs •
Three dedicated individual SDI black/test •
signal outputs, with HD signals through
7600HD option
Full-field test patterns (including FuBK) •
Analog audio, AES (including GLITS), and •
embedded audio test signals
GPS receiver option •
Optional NTP server for locking IT system •
and video system
Set-up and control via simple-to-use front •
panel display
Ethernet TFTP client for easy software •
upgrade and new test pattern download
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.
Applications
Dual-redundant master reference •
generator
Local slave reference generation •
Compact complete timing solution with •
reference and timecode generation
Reference generation for locking IT •
system and video system together
