Description

Specifies the minimum timebase position (minimum trigger delay) while in pattern lock when an 83496A/B clock recovery module is used. You can use this control to set the trigger-delay in Jitter Mode. In Jitter Mode, when making measurements on devices that employ a modulated clock, reduce the trigger's minimum timebase position to 24.1 ns to ensure that lock can be established. Jitter measurements on devices with a modulated clock can result in artificially higher measured jitter levels, due to the N1000A's trigger delay. Reducing the minimum timebase position reduces the amount of observed jitter. Reduce the value from a default of 40.1 ns to its minimum value of 24.1 ns.
