Tektronix® ECO8000
Automatic Changeover Unit
Available directly from Grass Valley for both IP and non-IP infrastructures, the Tektronix ECO8000 Automatic Changeover Unit is used in conjunction with a pair of Tektronix SPG8000A Master Sync/Master Clock Reference Generators (also available directly from Grass Valley) for most broadcast facility, studio, mobile and post-production timing applications. The ECO8000 is a highly versatile automatic sync and signal changeover unit with configurations and capabilities required to address modern master sync application and other advanced sync timing application.
