connectors. There is a Return Loss greater than 15dB, over the range 5MHz
to 1500MHz. Each input circuit is provided with automatic adaptive
equalisation circuitry suitable for cable lengths of at least 80 metres (of
Belden 8281 or equivalent coaxial cable).
Both HD-SDI outputs are to the same data structure and physical standard as
the inputs and provide output amplitudes of 800mV (± 10%).
Reference Video Input
The Imagestore HDTV will lock to the HD-SDI signal on input 1/A.
Power Requirements
Imagestore accepts power from a 110V or 220V, 60Hz or 50Hz, AC mains
supply. The mains supply input fuse is a T2A5 (2.5Amp Anti-surge) and
should always be replaced with a fuse of the same rating.
Interfaces
The Imagestore employs five types of control and image interfaces and a
summary of these is given in the following table.
