*Example in which initial delay jumps will not occur while actively updating while pulsing:
Width Delay Sync Source Period
CHA 10us 5us T0
100us
CHB 80us 10us T0
CHC 20us 4us T0
CHD 50us 5us CHC
80us(Width) + 10us(Delay) = 90us  NOT within 2us of Period (100us)
Pulse Width & Delay Notes
The following notes should be reviewed to understand the full capabilities and limitations of the
pulse delays (rising edges) and widths (falling edges) on the 9250:
-Delay (rising edge) notes:

Since a T0 signal output is not present, the delay accuracy is essentially the rising edge
accuracy from channel-to-channel.

There will be some inherent delay error when all channels have their respective delay values
set to zero; although, these errors should all be well within the delay accuracy
specification. Fine delay adjustments may be used to lower the error accordingly (i.e. The
fine delays may be adjusted to line up the rising edges if higher accuracy is needed. )
-Width (falling edge) notes:

The delay has 5ps resolution while the width only has 4 ns resolution; thus, when
dynamically adjusting the delay, the width will only update in 2ns steps. This assures that the
width accuracy specification is still met.
