* The number of effective lines in the 2I mode indicates the number of lines output from the Video 1 and 2 connectors.
– Determine and input each value for the colored columns.
– The above table shows an example values of the partial scanning mode. These values are measured by setting the trigger
pulse width to 100
µs and the time interval between the trigger falling edge and the external VD falling edge to about 1H
(32
µs). Mode 2 shows almost the same values as Mode 1. In this case, the trigger input affects the image output on about
the last 3 lines of the effective image interval.
BLKG interval Tb = 15 + n (n stands for the partial scanning setting value. When the 10th digit is 1 and the first digit is 3, n=13. The maximum value of
n is 49, and the minimum value of Tb is 25. When Tb ≤25, the BLKG interval is 25H, the constant value.
Effective lines X = T – (Tb + 2H)
BLKG interval Tb = 15 + n (n stands for the partial scanning setting value. When the 10th digit is 2 and the first digit is 6, n=26. The maximum value of
n is 99, and the minimum value of Tb is 45. When Tb ≤45, the BLKG interval is 45H, the constant value.
