Installation
Line Termination
Your instrument uses passive loop-through analog and reference inputs. Accordingly, the loopthrough inputs must be
terminated externally. It is important that this external termination meets accuracy and return loss requirements. Terminations
for loop-throughs on SDI or reference connectors in end-of-link setups must be 75
Ω
and DC coupled (good return loss
extends to DC). An appropriate termination would be a 75
Ω
End of Line terminator, Tektronix part number 011-0163-XX.
Compatibility of BNC Center Pins
Most video equipment BNC connectors, whether 50
Ω
or 75
Ω
, use a 50
Ω
standard center pin. Some laboratory 75
Ω
BNC
connectors use a smaller diameter center pin. The BNC connectors on the instrument are designed to work with the
50
Ω
standard (large diameter) center pins.
Do not use connectors or terminators with the smaller center pins. They could cause intermittent connections.
