MEASUREMENT METHOD
1) Input signal 1 (f = 100 kHz, picture period amplitude = 0.2 V_p-p) to pin 54.
2) When the G drive subaddress (06) data are changed to the maximum
(FE), the center (80), and the minimum (00), measure the picture period
amplitude of pin 14.

drive center in decibels.
(DRG+, DRG−)
4) Repeat steps 1) to 3) above with the subaddress (07) data and pin 15
instead of 14. (DRB+, DRB−)
1) Adjust the external power supply voltage until the ammeter reads 0.
2) When the pin 11 voltage is increased by 0.2 V, measure the ammeter
current.

T₂₂ ACL Characteristics
1) Input signal 1 (f = 100 kHz, picture period amplitude = 0.2 V_p-p) to pin 54.
2) Measure the picture period amplitude of pin 13 (v_ACL1).
3) Apply −0.5 V DC to pin 11 from an external power supply and measure
the picture period amplitude of pin 13. (v_ACL2)
