Note Characteristics
HA07 Curve correction
amount
Test Conditions
1. Set subaddress (00) data to 40H.
2. Input signal B (as shown in the figure below) to TP50.
3. Connect external voltage to #40 (curve correction), and measure phase change amount
(∆H#40) of #37 (H-OUT) output waveform at 1.5 V and 3.5 V.

HA08 Clamp pulse phase,
width and level
1. Set subaddress (00) data to 40H.
2. Input signal B (as shown in the figure below) to TP50.
3. Measure #47 (SCP output) clamp pulse phase (CP_S0), width (CP_PW0), and output level
(CP_V0) in relation to signal B.
4. Set subaddress (01) data to 81H, and repeat the step 3 above to measure (CP_S1), (CP_W1),
and (CP_V1).
5. Apply no signal input to TP50.
6. Measure #47 clamp pulse phase (CP_S2), width (CP_W2), and output level (CP_V2) in relation to
#39.
