MEASUREMENT METHOD
Input signal C-2 to the Sync Input pin (TP38).
f₀ = 100 kHz, picture period amplitude = 0.2 V_p-p
Turn DL mode off (subaddress (12), data (80)) and measure the picture period amplitude v_43off of the DL output
(TP43). Calculate the gain from the input (GYoff) by the formula shown below.
Turn DL mode on (subaddress (12), data (A0)) and measure the picture period amplitude v_43on of the DL output
(TP43). Calculate the gain from the input (GYon) by the formula shown below.
GYoff = 20Log ^{v 43off}
0.2
GYon = 20Log ^{v 43on}

1) Input signal C-2 to the Sync Input pin (TP38).
f₀ = 8 MHz, picture period amplitude = 0.2 V_p-p
2) Turn DL mode off (subaddress (12), data (80)) and measure the picture period amplitude v_438Moff of the DL
output (TP43). Calculate the gain from the input (GfYoff) by the formula shown below.
A
3) Turn DL mode on (subaddress (12), data (A0)) and measure the picture period amplitude v_438Mon of the DL
output (TP43). Calculate the gain from the input (GfYon) by the formula shown below.
GfYoff = 20Log ^{v 438Moff}
v _43off
GfYon = 20Log ^{v 438Mon}
v _43on
1) Input signal C-3 to the Sync Input pin (TP38).
A
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.
1) Input signal C-2 to the Sync Input pin (TP38).
f₀ = 100 kHz, picture period amplitude = 0.2 V_p-p
A
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).
