Product Overview
7600REF Models
Functionality specific to the three different 7600REF models is described
below.
7600 SD-REF Reference Signal Generator
This model features the following functionality:
• SD-SDI and analog video test signal patterns,
• Analog and AES audio test tones (including GLITS), and
• Full-field test patterns.
7600 HD-REF Reference Signal Generator
This model provides the same features as the SD version in addition to the
following:
• HD-SDI video test patterns, and
• A one slot HD Tri-level sync module provides 4 tri-level sync outputs,
each output individually configured from the front panel.
7600 MHD-REF Master HD Reference Signal Generator
This module expands the 7600 HD-REF model to include the following:
• A one slot GPS receiver module with a GPS antenna input and a
GPS 1 PPS output allows for locking to a high stability time and oscil-
lator reference,
• Two LTC timecode outputs available on the LTC D-25 connector and
the addition of VITC timecode to the SDI signal, and
• Network Time Protocol (NTP) with both Client and Server modes. NTP
is intended for synchronizing function for changeover units (such as
the 7620PX) to keep them both in sync.
