Setup of Sync Level on Signal Conditioning PCB
1. With the transmitter at rated power and an NTC7 Composite signal applied
to the input of the modulator, view the demodulated waveform on a waveform
monitor.
2. Adjust the sync level potentiometer on the front panel clockwise for more sync or
counter clockwise for less sync to obtain 40 IRE of sync.
3. Maintain the white bar level at 100 IRE by adjusting the video modulation
potentiometer on the front panel.
Varying these two pots can increase and decrease the
output power, so this should be carefully monitored.
