Reliable

The SPG8000A supplies the reliability needed in modern facility timing systems by shipping standard with hot swappable dual power supplies The SPG8000A is designed to run as a standalone master or under an external reference input, locking to black-burst, tri-level sync, GPS or PTP.

When reliability is critical and you need a backup master reference, the ECO8000 auto changeover unit complements the SPG8000A. It is user configurable to monitor and changeover analog video, SDI video, timecode and AES/EBU digital audio signals. Quickly setup your PTP network and avoid downtime using pre-loaded ST2059-2 and AES67 profiles for reliable synchronization and an unshakable master reference

Future Proof

Build synchronized IP media networks using the PTP software upgrade option. It provides 2 PTP engines with rock solid ST 2110 and AES67 network references, full compliance to IEEE1588 and support for GPS reference

Bridge your SDI equipment to IP with PTP Follower providing analog and digital references locked to your network timing

Invest in a complete master reference platform loaded with UHD (SQD), GPS, NTP, AES. Activate PTP when you need it through simple software licensing

Flexible

Control your SPG8000A directly using the front control panel or remotely with a built-in WebUI.

Design the system you need using PTP (Precision Time Protocol), NTP (Network Time Protocol), GPS time synchronization, and UHD Quad link outputs. Generate all the required reference timing signals needed to precisely time complex broadcast facilities, including: PTP Grandmaster and Follower, Black Burst, Tri-Level Sync, Word Clock, and DARS. The SPG8000A also provides timecode generation delivered through dedicated LTC outputs or embedded VITC through analog and ATC on SDI video outputs.

Design and Deploy

Verify the signal chain and remote links using 2 independent 3G-SDI pattern generators, each providing pattern with text and logo overlay. Each output is embedded with user selectable test tones and ATC. SDI pattern generators also produce quad-link UHD patterns in Quad-Division multiplex format.
