b (1) BUS control data preset.
(2) Horizontal oscillation frequency is 15.75 kHz (00).
(3) SW6 open. Measure the Voltage of pin 6 V6 (no external supply).
(4) Connect external supply with pin 6, and supply the voltage (V6).
(5) Input signal (below figure) to pin 21 (SYNC1-IN). When INPUT SW is SYNC1-IN , measure V1 and V2 of pin
6 wave form.
(6) Supply V6 − 0.1 V and V6 + 0.1 V to pin 6, then measure V3 and V4.
(7) Calculate by following equations.
ID1 [µA] = (V1 [V] ÷ 1 [kΩ]) × 1000
ID2 [µA] = (V2 [V] ÷ 1 [kΩ]) × 1000
ID3 [µA] = (V3 [V] ÷ 1 [kΩ]) × 1000
ID4 [µA] = (V4 [V] ÷ 1 [kΩ]) × 1000
