RACK-UP
Model RU-VDA4
Video Distribution Amplifier
POWER CONNECTION: Connect a single-ended 24 Vdc power source to the +24 terminal. Connect the ground return from that
supply to the adjacent GND terminal. Power supply and circuit grounds are common.
FRONT PANEL CONNECTIONS
INPUT: Connect video input to the IN jack. If the input signal is to continue on to another piece of equipment which will terminate
the input, connect a cable to the LOOP OUT jack; connect the other end of this cable to the terminating equipment. If no loop
output is used, connect a 75 Ohm terminator to the LOOP OUT jack.
OUTPUT: Connect the coaxial cable to the desired output(s) on the RU-VDA4, and label them as desired.
GAIN ADJUSTMENT: Adjust the GAIN potentiometer for 1 Vp-p video level on your instrumentation. In the absense of test
equipment, the 1V VIDEO INTO TERMINATED LOAD LED may be used. First turn the gain counter-clockwise. Then advance the
GAIN clockwise until the 1V VIDEO INTO TERMINATED LOAD LED just illuminates.
