Safety Summary
Do not operate with suspected equipment failure — If you suspect product damage
or equipment failure, have the equipment inspected by qualified service
personnel.
Ensure mains disconnect — If mains switch is not provided, the power cord(s)
of this equipment provide the means of disconnection. The socket outlet
must be installed near the equipment and must be easily accessible. Verify
that all mains power is disconnected before installing or removing power
supplies and/or options.
Route cable properly — Route power cords and other cables so that they ar not
likely to be damaged. Properly support heavy cable bundles to avoid connector damage.
Use correct power supply cords — Power cords for this equipment, if provided,
meet all North American electrical codes. Operation of this equipment at
voltages exceeding 130 VAC requires power supply cords which comply
with NEMA configurations. International power cords, if provided, have
the approval of the country of use.
Use correct replacement battery — This product may contain batteries. To
reduce the risk of explosion, check polarity and replace only with the same
or equivalent type recommended by manufacturer. Dispose of used batteries according to the manufacturer’s instructions.
Troubleshoot only to board level — Circuit boards in this product are densely
populated with surface mount technology (SMT) components and application specific integrated circuits (ASICS). As a result, circuit board repair at
the component level is very difficult in the field, if not impossible. For warranty compliance, do not troubleshoot systems beyond the board level.

Reference Generator
Product Overview
The 7600REF Synchronizing Pulse Generator is one of the most flexible SPG
units available on the market today. It is suitable for any digital or mixed
format environment where a high quality digital SPG is required. This
manual covers the installation and operation of the three available models
along with full technical specifications.
Refer to 7600REF Models on page 18 for specific functionality available for
each of the model types: 7600 SD-REF, 7600 HD-REF, and 7600 MHD-REF.
Each 7600REF model has the following basic functionality:
•Oven-controlled reference oscillator allowing the unit to be used either
as a master reference, or to follow another unit,
•Five analog outputs,
•Three SD SDI black outputs with four channels of embedded AES
silence and EDH,
•Two AES silence outputs,
•Each output selectable to either 525 or 625 operation,
•Each input individually timed,
•Dual power supplies that auto-sense line rates with separate mains
connections for power backup in the case of one power supply failure,
•Selectable clock output of 10 MHz/27 MHz/Word Clock,
•Looping Genlock input,
•10 MHz Reference input
•ANALOG AUDIO/REMOTES connector that provides:
•A serial communication port,
•Analog audio output test tones,
•Power fail output status,
•Fan failure status, and GPI input output control connections.

Product Overview
7600REF Models
7600 SD-REF Reference Signal Generator
7600 HD-REF Reference Signal Generator
Functionality specific to the three different 7600REF models is described
below.
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.
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 oscillator 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.

Installation
Follow the instructions below to unpack, install, and cable the 7600REF
frame.
Carefully unpack the unit from its packing box and check for signs of
damage. Check the contents of the box against the packing list and your
original order to ensure that you have received the correct parts.
In the event the unit has been damaged or does not match your order,
contact the Thomson Grass Valley Sales office listed on Contacting Grass Valley on page 4.
All hardware modules are installed at the factory and shipped inside the
unit. Module functionality included in the model configuration depends
on the model type (see
ality included with the model is already installed and enabled.

Rack Mounting
The 1 RU rack frame has integral rack mounting ears on the frame front
cover for direct mounting into a standard 19 inch rack. Carefully place the
unit in your rack and firmly attach it to the rack using four standard rack
screws (not provided).
CAUTION This unit has air intakes on one side of the unit and fan-assisted exhaust vents
on the other side of the unit. Ensure that these have an unobstructed air flow,
otherwise the unit will overheat. Pay particular attention to ensure that any
rack wiring or cable trays do not obstruct the vent. 60 mm (2.36 in.) of clear
space should be allowed between the vents and any potential obstruction.

AC Mains Connection and Fusing
CAUTION The power supply cord is used as the main power disconnection device.
Ensure that the socket outlet is located/installed near the equipment and is
easily accessible.
ATTENTION Le cordon d’alimentation est utilisé comme interrupteur général. La prise de
courant doit être située ou installée à proximité de l’équipement et être facile
d’accés.
Each 7600REF model is fitted with two independent AC mains power supplies. Each power supply has its own dedicated IEC mains plug on the rear
of the unit.
The correct power cords for the line standard of the region the product has
been shipped to are included in the shipping box. The power supplies used
in this the unit are a switch mode design and are auto-sensing to handle a
wide input voltage range. See Power (page 79) in the Specifications table
for the voltage and frequency ranges.
Power Supply Replacement
If one of the power supplies fails, a replacement unit can be acquired from
Customer Service and can be installed by the customer in the field.
To replace a 7600REF power supply:
CAUTION Make sure power to the unit is completely disconnected by removing both AC
cords from both power supply connections on the rear of the unit.
1. Remove the top cover of the frame by removing the 13 screws holding
the cover to the frame. Determine which power supply unit needs to be
replaced.
2. Tilt the frame up and on the bottom of the frame remove the two screws
holding the defective power supply unit to the frame chassis.
3. On the front of the power supply unit, remove the 2-pin connector
labeled J1 coming from the AC Main assembly. Note the orientation of
the connector when removing it.
