APPENDIX C

Cable Lengths and Distribution Amplifiers

To aid in achieving the bet results from your installa- tion, we suggest the following minimum standards for cable runs when an LD100 is used.

To preserve the video quality of the LD100, the signal path should be no more than –3db down at 25 MHz through a 75 ohm cable. Any distribution amplifier should have a bandwidth no less than –3db down at 25 MHz.

The following cable lengths are the maximum rec- ommended continuous lengths of 75 ohm coax cable with BNC connectors on each end as well as 15 pin VGA cable (when using the VGA output).

Cable Type	Maximum Length
Mini BNC cables, 75 ohm		100	Feet
1.15nS/Foot propagation
RG-59/U type cable, 75 ohm		150	Feet
75 ohm precision video cable		200	Feet
Belden 8281
15 pin, high resolution VGA cables		25	Feet
utilizing individual high resolution
mini-coax cables for each signal from
LD100 to monitor.
