No signal input.
Measure T1 and T2 (as shown in the figure below) from #26 (H-OUT) output waveform when
subaddress (00) data is 80H and A0H. Calculate duties (TH
equation:
TH = T1/(T1 + T2) × 100 %
Set SW20 to open.
Set subaddress (00) data to 01H and measure horizontal free-run frequency (F15K) according
to #26 (H-OUT) output waveform.
Set subaddress (00) data to 00H, 41H, 81H, C0H, and C1H. Measure horizontal free-run
frequency F28K, F31K, F33K, F37K, and F45K as in the step 2 above.
Set subaddress (00) data to 01H.
Connect 10-kΩ resistor between #20 and V
according to #26 (H-OUT) output waveform.
Connect 68-kΩ resistor between #20 and GND. Measure horizontal frequency (F15K
according to #26 (H-OUT) output waveform.
Set subaddress (00) data to 00H, 41H, 81H, C0H, and C1H. Repeat the steps 2 and 3 above
and measure horizontal frequencies F28K
F33K
Set SW26 to open.
Measure voltage at High (V26
Set SW20 to open.
Connect external power supply to TP 20, and set subaddress (00) data to 01H.
Apply V
#26 (H-OUT) output waveform. Calculate frequency change rate (BH15K) using the following
equation.
BH15K = (FB − FA)/0.1
Set subaddress (00) data to 00H, 41H, 81H, C0H, and C1H. Repeat the step 2 above, and
measure frequency change rate BH28K, BH31K, BH33K, BH37K, and BH45K
