*Example in which initial delay jumps will not occur while actively updating while pulsing:

Width

Delay

Sync Source

Period

CHA

10us

5us

100us

CHB

80us

10us

CHC

20us

4us

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.
