Effect of cable length

Performance

The performance of each acquisition path is as follows:
N u m b e r o f p i x e l s / l i n e ( i n c l u d i n g s y n c a n d b l a n k i n g )
N u m b e r o f l i n e s / f r a m e ( i n c l u d i n g s y n c a n d b l a n k i n g )
D o w n l i n k b i t r a t e ( p e r l i n k )
U p l i n k b i t r a t e ( p e r l i n k )
The maximum data transmission rate that you can achieve depends on the length
of your coaxial cable, the quality of the cable, as well as the type of PCIe slot to
which you connect your Matrox Radient eV-CXP.
For lengths greater than 40 m, the longer the cables, the lower the maximum
possible bit rate. High-quality cables, such as Belden 1694A cables, will allow for
the highest possible bit rates. The table below outlines the bit rates that you can
expect to achieve at certain lengths, using Belden 1694A cables, as well as the bit
rates possible when connecting to a single video source using link aggregation (2,
3, and 4 cables).
