V SIN Waveform Adjustment
(DB Board)
1. Input the signal of its frequency is 64 kHz.
2. Set the data value of H SIZE COARSE to “250.”
3. Set the data value of V SIZE COARSE to “180.”
4. Connect an oscilloscope to TP101.
5. Adjust RV102 so that A and B sections of a waveform
become even with C section as shown in the figure.
6. Adjust RV101 so that C section of a waveform is 0 V.
