The scope view is showing a full serial data break down of an ultra-high end reference 10 Mhz master clock, but that I mean I can look at full jitter analysis 16 sperate characteristics, electrical noise both frequency & time domain, digital X/talk, spectral analysis of jitter/electrical noise as well as eye diagrams in four line mode each with up to 88 different types of measurements applied.
In layman’s terms a significant ability to view pretty much every possible aspect of the signal in minute detail for example in the first image on the lower right had side of the screen is the 12th mini screen display of measured random jitter + bounded uncorrelated jitter histogram which is extrapolated using the dual dirac method of forming the RMS resultant of the RJ which is unbounded jitter but does have a periodic cycle Lecroy's uses I believe a spectral method of calculational formular to display the finished screen measurements. BUJ includes PJ, but it also includes other bounded uncorrelated effects that don’t cause clear peaks in the jitter spectrum. One common source with these characteristics is cross talk from adjacent traces on printed circuit boards or coupling within the chips themselves. The Spectral method of jitter separation will see cross talk as noise in the jitter spectrum, so it will only separate the PJ peaks and attribute the other effects to RJ.

What this mean in English is that jitter can measured & quantified for many different causes and areas that are well outside the considered norm's for the various areas of electronic activity, RF/Power electronics/Communications/radar etc.

The graph is showing a 732fs histogram span (there are 1000 femtoseconds in a picosecond) with 2000 bin width and 5000 high possibilities in each of those bins. While performing this at 20 billion samples a second. So, it’s pretty accurate.
It’s also great for decoding All forms of ETHERNET information and traffic, USB physical layer testing and protocol analysis, full three phase vector power analysis, jitter investigations separately, DDR PCIE debug. automotive ethernet debug and investigations, a dual spectral analyser model plus ref channel and a really neat digital power management app that we can watch drops and sags on even very small power rail sand measure the recovery time from load on to off and what noise is caused on the rails while this is happening. I can also leave the scope running with wave scan and it can be set to look for anomalies even one in say 10 million it will find it. Then you can play back EACH frame individually like a film to find the exact point of incidence. Also virtual probing (Woooo matron) which allows you to 'remove' an unknown portion of the circuit for the measurement even if you can't get in to physically probe hat portion of the circuit. etc.
