Example
Calculating the response time for a cascaded system without beam coding in which fields
a
re configured with floating blanking:
Line Required detail Response time
1 Host: 750 mm protective field height, resolution 14 mm 16 ms
2 Guest 1: 300 mm protective field height, resolution
40 mm
+ 9 ms
3
Guest 2: – + 0 ms
Greatest response time from lines
1 to 3: 16 ms × 0.5 =
+ 8 ms
4 Only if floating
blanking is used:
Deduct 4 ms here. – 4 ms
5 If single guest is used, then add 8 ms here. (If no guest is
used or two guests are used, do not add anything here.) + 8 ms
6 Total response time to be taken into account = 37 ms
