The Jitter Deviation parameter is specified as the maximum ± time excursion for any jitter. The width of the pulse (100%-100%) is changed by jittering the falling edge of the pulse using the selected probability model.
For jitter types the jitter is applied on the falling edge of the pulse as follows.
- no jitter deviation is applied.
- the jitter deviation is centered around the falling edge of the pulse. Any deviation is probable within the time specified by the Jitter Deviation entry. Any jitter deviation has an equal probability of occurring during the time interval specified in the Jitter Deviation text box. The jitter is distributed uniformly around the falling edge of the pulse.
- the jitter deviation is centered around the falling edge of the pulse. Any deviation is probable within a one sigma of the limits of the jitter deviation time entry and follows a normal distribution model. The mean, mu, is the falling edge of the pulse and any jitter deviation has an equal probability of occurring during a one standard deviation (1 sigma) variance following the probability density function.
- the jitter deviation is centered around the falling edge of the pulse. Any deviation is probable within the time specified by the Jitter Deviation entry. Any jitter deviation has an equal probability of occurring during the time interval specified in the Jitter Deviation text box. The jitter follows a u-shaped distribution around the falling edge of the pulse.
