Notes
3G-SDI and 12G-SDI signals are
very high speed digital signals which
require better quality coaxial cable
than conventional analogue video.
The data rate is 3 Gigabits per
second.
In choosing cable length and
connectors for any installation the
frequency response loss in decibels
should be proportional to √f, from 1
MHz, to 3 GHz.
Only one remote connection (RS232
or LAN) should be used at any one
time.
