Video Input Gain Setting

Rev 1.0
The LED on the front panel of the input card illuminates to show power. Each time that a
serial message is received via the backplane and is addressed to the module, the LED will
flash off briefly.
Each input has an adjustable gain, which is used to adjust for differing levels of the video
input signal. SW2 must be set to ON to adjust the gain
Figure 3-8 Video Input Gain Enable/Disable (SW2) and Termination (SW1).
This level should be set such that the input signal is amplified to provide 2 volts (0.6V sync
and 1.4V peak white) on the backplane, when the backplane is terminated into an output
card. Should the output card be calibrated, then the input may be set to provide a 1 volt
(0.3V sync and 0.7V peak white) when terminated into a 75 ohm load.
