Video signal
Oscilloscope
· · · · Receive 100% color bar signal at video input 1.
· · · · Enter the adjustment mode and adjust the amplitude level of each signal in the following steps.
1. Y signal
With [VOLUME+/-] buttons of the remote control transmitter, adjust the value appearing below YGAIN indication so that the
value below MAX indication becomes B8.
2. B-Y signal (TP238)
With [VOLUME+/-] buttons of the remote control transmitter, adjust the value appearing below B-Y indication so that the
amplitude (yellow-blue) at TP238 becomes 0±0.03V.
3. R-Y signal (TP236)
With [VOLUME+/-] buttons of the remote control transmitter, adjust the value appearing below R-Y indication so that the
amplitude (cyan-red) at TP236 becomes 0±0.03V.
