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. This changeover unit offers exceptional reliability, stability and high availability and is designed with optional high bandwidth input...
