The following is a simple adjustment method. �Simple Adjustment� Note : Since exact adjustment cannot be performed, remember the positions of the controls before performing the adjustment. If the positions after the simple adjustment are only a little different, return the controls to the original position. Procedure:
5. Connect the osilloscope between TP (TE) and TP (VC). 6. Adjust RV703 so that the waveform is as shown in the figure below. (tracking gain adjustment) � Correct Example
VOLT/DIV : 100 mV TIME/DIV : 2 mS
� Incorrect Examples (fundamental wave appears)
low tracking gain VOLT/DIV : 100 mV TIME/DIV : 2 mS 0V
1. Keep the set horizontal. If the set not horizontal, this adjustment cannot be performed due to the gravity against the 2-axis device. 2. Insert disc (YEDS-18) and push the � button. 3. Connect the oscilloscope between TP (FE) and TP (VC). 4. Adjustment RV704 so that the waveform is as shown in the figure below. (focus gain adjustment) � Correct Example
VOLT/DIV : 100 mV TIME/DIV : 2 mS 100 mV 0V
high tracking gain (higher fundamental wave than for low gain) VOLT/DIV : 100 mV TIME/DIV : 2 mS
0V
� Incorrect Examples (DC level changes more than on adjusted waveform)
low focus gain VOLT/DIV : 100 mV TIME/DIV : 2 mS 250 mV
Adjustment Location : See page 19.
0V high focus gain VOLT/DIV : 100 mV TIME/DIV : 2 mS 100 mV 75 mV 0V
