Tektronix SPG422

The SPG422 is a master sync generator
designed to meet the transitional
and long term needs of the serial
component digital post production
and operational environments. While
component digital is gaining
momentum, many facilities will still be
largely analog with digital islands and
virtually all will output materials in
analog form. The SPG422 provides
the basic timing and test signals
needed to operate these mixed format
environments.
