Incorrent Examples (DC level changes more than on adjusted
waveform)
5.
Connect the oscilloscope between TP (TE) and TP (VC).
6.
Insert disc (YEDS-18) and press the CD
^
button.
7.
Adjust RV704 so that the waveform is as shown in the figure
below. (tracking gain adjustment)
Incorrect Examples (fundamental wave appears)
VOLT/DIV : 0.1V
TIME/DIV : 2ms
0V
low focus gain
high focus gain
low tracking gain
