The FP-VDA4 is the ideal choice in many applications where video signals need to be distributed. Video input and output connections are made on the top-panel BNC jacks. Power connections are made using either the full-size barrier block terminals or a dc power jack located in one end panel. A second dc power jack is provided on the other end panel for connecting additional FLAT-PAK modules.

The FP-VDA4 has two jacks in the bridging input stage. One jack is for the input signal; the other is a loop-through output of the source signal. If 75 Ω termination of the input signal is required, the terminator (provided) is plugged onto the LOOP OUT jack. Gain is user adjustable from the top panel. The GAIN potentiometer allows adjustment from unity to +6 dB. Four source-terminated outputs are provided through the BNC output jacks. Unused outputs need not be terminated.
