Before You Begin
The SRG-4500 is designed for high stability Master Sync and time reference operation. The product provides a
comprehensive range of accurate video, audio and time reference and test signals including: Analog Composite
Video, Analog Composite Black-Burst, Tri-Level Sync, Serial Digital (SDI) Test & Black (SD, HD, 3G, and 4K
(Quad and 2SI), analog audio, AES/EBU Audio, DARS, Word Clock, and time reference signals including,
Timecode (LTC and VITC), and NTP plus inputs for an external frequency reference and a GPS reference.
Overview
The SRG-4500, in its base configuration, is supplied as a Composite SPG with multiple Color Black and SD-SDI
outputs. The Color Black outputs are configured to be capable of providing Tri-level Syncs. Interfaces for
AES/EBU Digital Audio outputs, Analog Audio outputs, LTC outputs, a GPS input, and an external frequency
reference input are also standard features with the SRG-4500. Dual N+1 power supplies are also standard.
Option Keys
Additional options above the base configuration are enabled using special Option Keys. These options are:
• GPS-4500
• NTP-4500
• PTP-4500
• UHD-4500
The connectors and associated hardware for these options will already be present - the Option Keys simply extend
the range of signal options on the associated video outputs (see diagrams below), or enable the option in the case of
GPS, PTP, and NTP.
Applications
Use the SRG-4500 in the following applications:
• SPG and time reference generator for broadcast, studio, outside broadcast, SNG and post-production facilities
• Master or slave (Genlock) operation
• Link testing, Fly-Away packs and others
Features
The SRG-4500 includes the following:
• High Stability Internal Reference
• Genlock to the NTSC/PAL Black-Burst signals, time to remote NTP server, or optionally to GPS
• Frequency Lock to 10MHz
• 2 Composite Analog Video signal o 2 Composite Analog Black-Burst signal outputs
