Hi,
I'm interested in jitter measurements on my X2000 (70MHz, 4ch) scope. One method I've seen is to trig on an edge and then view a histogram of the transitions of the same type of edge ahead in time.
My goal is to compare different XOs and power supply topoligies for audio oscillators (10-25MHz range) and also for audio test signals (1-20kHz).
I've looked through the menus on my X2000 without finding anything resembling "histogram" or "jitter". Is there a way to measure such things on my scope? Is there an option I can buy to enable it?
Thanks,
Borge

Many of Agilent's higher performance scopes have jitter options. In general, that option alone costs 3-5 times the cost of the DSOX2004A that you have. Add in the cost of the scope, and you see the reason it's not available on a scope hat costs less than $2000.
There is a slightly lower cost solution. Get a copy of InfiniiView, and buy a jitter package to go with it. You can unload the scope data onto a PC running InfiniiView and do jitter analysis on the captured data.
Both InfiniView and the Jitter packages are available with free 30 day licenses, so if this is a one time thing, you may not have to buy anything.
For little or no cost, you could get a copy of Python, and write your own jitter package, then make exactly the measurements you are interested in.
