SETTLING TIME is the interval required for the pulse level to enter and remain in the specified level
ACCURACY RANGE, measured from the 90% AMPLITUDE point.
3.13 Pulse Parameter Limitations
The following formulas express the limits on Period, Width, and Delay.
Single Pulse per Period Modes
(Un-delayed, Delayed, Counted Burst with single pulse mode)
[Period - (Width + Delay)] must be > 10 ns
0.99 * Period must be > (Width + Delay)
Pulse max = 10.00 s
Pulse min = (Width + Delay + 10 ns), but not less than 20 ns
Width max = [(Period * 0.99) - Delay – 10 ns], but not more than 9.89999 s
Width min = 10 ns
Delay max = [(Period * 0.99) - Width – 10 ns], but not more than 9.89998 s
Delay min = 0
Single Pulse Transition Time Restrictions
Width must be > 1.3 * Leading Edge
(Period - Width) must be > 1.3 * Trailing Edge
Double Pulse per Period Modes
(Paired Pulse and Counted Burst with Paired pulses)
Delay must be > Width
0.99 * Delay must be > (Width + 10 ns)
Pulse max = 10.00 s
Pulse min = (Width + Delay + 10 ns), but not less than 40 ns
Width max = [(0.99 * Delay) – 10 ns], but not > 4.85000 s
Width min = 10 ns
Delay max = [(Period * 0.99) - Width –10 ns], but not > 9.80000 s
Delay min = (Width + 10 ns)
Double Pulse Transition Time Restrictions
Width must be > 1.3 * Leading Edge
(Delay - Width) must be > 1.3 * Trailing Edge
[Period - (Delay + Width)] must be > (1.3 * Trailing Edge)
