Sync Input~DL Output AC
Gain
A
1)
Input signal C-2 to the Sync Input pin (TP38).
f0 = 100 kHz, picture period amplitude = 0.2 Vp-p
2)
Turn DL mode off (subaddress (12), data (80)) and measure the picture period amplitude v43off of the DL output
(TP43). Calculate the gain from the input (GYoff) by the formula shown below.
3)
Turn DL mode on (subaddress (12), data (A0)) and measure the picture period amplitude v43on of the DL output
(TP43). Calculate the gain from the input (GYon) by the formula shown below.

1)
Input signal C-2 to the Sync Input pin (TP38).
f0 = 8 MHz, picture period amplitude = 0.2 Vp-p
2)
Turn DL mode off (subaddress (12), data (80)) and measure the picture period amplitude v438Moff of the DL
output (TP43). Calculate the gain from the input (GfYoff) by the formula shown below.
3)
Turn DL mode on (subaddress (12), data (A0)) and measure the picture period amplitude v438Mon of the DL
output (TP43). Calculate the gain from the input (GfYon) by the formula shown below.

A
1)
Input signal C-3 to the Sync Input pin (TP38).
2)
When the amplitude A of signal C-3 is increased from 0, observe the change in the picture period amplitude of
the DL output (TP43). With DL mode turned on and off, when the output amplitude stops changing in a linear
direction, measure the input signal amplitude A.

Sync Input~DL Output
Transfer Characteristics
A
1)
Input signal C-2 to the Sync Input pin (TP38).
f0 = 100 kHz, picture period amplitude = 0.2 Vp-p
2)
Turn DL mode on (subaddress (12H), data (20)) and measure the amount of delay TYLD from the Sync Input
(#38) to the DL output (TP43).
Note 1: Where the bus data are not specified, set the preset value.
Note 2: Ensure the sync signal is always input to TP38 (SYNC IN).
