video analyzer with the serial digital video signal or by an oscilloscope with the
analog audio and video signals extracted from the serial digital video signal.
The following settings are recommended for the audio and video signals when
you use this mode:
Audio signal (CH1 and CH2 of Group 1): 10000 Hz, -20 dBFS
Video signal: 100% Flat Field
NOTE.
