7600HD-REF
HD/SD Timing Generator

The 7600HD-REF 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 7600HD-REF with dual-redundant power supplies and the ability to interface to the 7620PX changeover unit for backup. The 7600HD-REF 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 7600HD-REF an ideal unit for OB operation.

  • 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 blackburst outputs
