Input signal C-2 to the Sync Input pin (TP38).
Turn DL mode off (subaddress (12), data (80)) and measure the picture period amplitude v
(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
(TP43). Calculate the gain from the input (GYon) by the formula shown below.
Input signal C-2 to the Sync Input pin (TP38).
Turn DL mode off (subaddress (12), data (80)) and measure the picture period amplitude v
output (TP43). Calculate the gain from the input (GfYoff) by the formula shown below.
Turn DL mode on (subaddress (12), data (A0)) and measure the picture period amplitude v
output (TP43). Calculate the gain from the input (GfYon) by the formula shown below.
Input signal C-3 to the Sync Input pin (TP38).
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.
Input signal C-2 to the Sync Input pin (TP38).
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).
