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
