Re: Trace jitter

Clark Foley

One unexpected source of jitter on the 11800 series is the timebase delay/position setting. The horizontal position is not phase locked to anything. As such, long delay times (e.g. greater than 1us) result in a wondering trace, horizontally. Verify that the horizontal position is very small, on the order of 10's of nanoseconds before messing with the hardware. The 11800 series gives great results for short delay times but not as you approach 1us.
