8937 Module
Refer to
for cabling the 8937 module. Cabling to and from the
module is done at the back of the Gecko 8900 video frame or on the corre-
sponding 89000V-R rear module of the GeckoFlex frame as described
below.
Loop-Through Input
One serial digital component input is provided at differential loop-through
BNCs J9 and J10. If the unused input is not looped to another device, it
should be terminated in 75 ohm.
Outputs
There are eight outputs for the 8937 module at BNCs J1 through J8. Output
destination equipment should have an input impedance of 75 ohm unless
it has loop-through inputs, in which case the loop-through inputs must be
terminated into 75 ohm. All outputs are in phase with the input signal.
