UNIVERSAL SPG CHANGEOVER - CO490

The Sigma Electronics CO490 is a universal, modular automatic SPG changeover unit. It works in conjuntion with Sigma's full-featured TSG490 SPG and Test Pattern Generator but can be easily incorporated into any system currently containing an SPG or test pattern generator. It accomodates up to 12 channels where channel 1 is a measured channel, 2 - 6 can be additional measured channels and 7 - 12 can be either measured or slaves.

To allow for mixed format requirements and offer maximum flexibility, each measured channel can be set to measure analog blackburst, SDI video, or AES/EBU audio (75W) and will generate a 'contribute to local request.' Each measurement channel may generate a 'contribute to global request' and can be selected to switch if it receives 'local request to switch' and/or 'global request to switch.'

Up to 12 channels in 1RU

Front panel audible and visual fault indication

Manual override facility

Measure channels can measure analog blackburst, SDI video, HDTV tri-state sync, Timecode, or AES/EBU audio

Measure channels will generate a 'contribute to local request'

Measure channels may generate a 'contribute to global request'

Measure channel can be selected to switch if it receives 'local request to switch' and/or 'global request to switch'

Each slave channel requires a measurement channel

Slave channels switch when measure channel switches

Measure channels always report errors even when not selected to switch

The error report is persistent and is only reset by the user
