Panasonic WV-CL934, WV-CL930 Adjustment of phase in power supply synchronization mode LL, Step

Adjustment of phase in power supply synchronization mode (LL)

The adjusting video signal of the camera and the criterial external synchronizing input signal are connected to a 2-input oscilloscope and the phase is adjusted.

Note:

Movement of the camera or presence of a spike noise in the power line may cause vertical phase change. In such a case, adjust the phase again.

Follow the procedure in the next page to adjust the phase.
