The SRG-4400 is a 1RU state of the art master reference and 3G/HD/SD SDI test signal generator designed to exacting specifications. The SRG-4400 is the ideal choice for supplying all of the required reference timing and test signals needed in today’s complex broadcast facilities. It provides all the reference (Color Black, Tri-Level Sync), timing and test signals, including LTC and VITC, together with analog audio, AES audio and Wordclock/DARS, needed to satisfy any application in PAL, NTSC, SD SDI, HD SDI, & 3G SDI and mixed standard installations.

The SRG-4400 ships standard with hot swappable dual power supplies which are accessible from the front panel. Adding the companion ACO-4400, Automatic Changeover unit, the SRG-4400 supplies the reliability needed in modern facility timing systems.

The SRG-4400 comes with advanced networking control via the DashBoard control system. The SRG-4400 also has NTP (Network Time Protocol) and GPS time synchronization options.

The SRG-4400 is designed to run as a master in standalone or under an external reference input. Where it is critical to have a backup master reference, the ACO-4400 auto changeover unit complements the SRG-4400. This can be user configured to monitor and changeover analog video, SDI video, timecode and AES/EBU digital audio signals.
