Description
Single Time between pointer adjustments is 30 s.
Burst Time between bursts of 3 pointers for STS pointers is 0.5 ms and for VT
pointers is 2 ms.
Time between pointer bursts is 30 s.
Phase Transient Time between pointer movement burst of seven pointers is 0.25 s,
0.25 s, 0.5 s, 0.5 s, 0.5 s, 0.5 s.
Time between pointer bursts is 30 s.

Time between STS pointers has a range of 0.034 s to 10 s with a
resolution of 1 ms.
Time between cancelled pointers is equal to: (time between pointer
movements
N), where N is selected to be the smallest integer that
makes the product
30 s.
