You still won't believe that there is a world of realtime update, and its completely different to segmented capture.
And you still show a lack of grasp of some basic facts.
Pretty much every deep memory DSO has the fastest update rate in segmented mode. The InfiniiVisions like the DSOX are an exception because the MegaZoom ASIC is designed for a high real-time update rate, on the other hand the small memory hampers its update rate in segmented mode.
If the Lecroy products offer fast realtime update rates, why do they not advertise or specify it?
Why should they specify it? The update rate varies a lot depending on time base settings and memory settings (yes, you can set memory on these manually, it's not auto only as in the InfiniiVision Series). That's why pretty much every manufacturer just posts the maximum rate the scope can reach. I didn't hear you complain that Tek or R&S only specify the maximum rate, and to some extent even Keysight does.
And as to why they don't advertize it, well I have to guess here but it seems they have plenty of other interesting features they can base their marketing on (you've seen the list). You could ask as well why they don't have these ridiculous "ours-vs-theirs" comparisons as pretty much every other big brand that obviously has not enough to say about their product and therefore needs to bash the competition.
Why has no-one measured it and shared the results?
I don't know? Maybe because the waveforum update rate is much more important for entry level scopes which have pretty basic triggers only, and are often used in a similar way as analog scopes (i.e. the user staring at the screen waiting to see a glitch) and less so for a high-end scope.
But hey, here's a chance for you to shine! Why don't you get one of these scopes (they might even give you a loaner), do some waveform rate testing and publish the results?
Probably because it doesn't have a fast realtime update rate.
As I said, there's your chance! Why don't you go ahead and prove that the LeCroy scope (pick one, WRXi, WRXi-A, WR6zi, WP7zi, WM8zi, WR8k) doesn't have a fast waveform update rate, or one that is inferior to the competition?
BTW: ever had a look at the Keysight Infiniiums? I guess not. They all have pretty low real-time update rates, and reach their maximum in segmented mode. Funny enough, most of their high end scopes are well below the 1M wfms/s mark even in segmented mode.
As has been the subject of many lengthy threads on this forum, realtime update rate has some niche uses but that and the similarly fast mask testing are the point of difference (selling feature) in specifications for the Keysight X series scopes. Having that realtime speed in a 4/6GHz scope is quite a unique position.
Yes, it's unique and pretty useless because the limitations of that architecture, but it's obvious you've never used an advanced high bandwidth scope in a demanding test scenario or you'd had known that yourself. You really think I'd use some primitive tool like mask testing for searching for a glitch when on a newer high-end scope I have a wide range of tools available to detect, identify and quantify any type of irregularity in a repetitive and non-repetitive signal?
Not that the fast real-time update of the DSOX6k wouldn't be nice, but it comes at significant costs, not just in price but most importantly in features and capabilities. You have to have very low expectations if you think 500k of memory are useful in a 6Ghz scope sampling at 10Gsa/s.
But as I said, it's clear you've never come into a situation requiring a scope of this class, so I'm cutting you some slack here.
You can make disingenuous comparisons between the Lecroy 8000 and Keysight 6000X series all day long until you are blue in the face, but it forgets that they are targeting different uses/markets/purposes. If you want to make relative comparisons look at the Keysight offerings that have deep memory and Windows 7 operating systems such as the models mentioned to you, they are 20-30% more expensive but otherwise hitting specifications that are almost identical (and small differentiators such as more compliance packages...).
That must be one of the most stupid arguments I've heard in a long time, and I heard quite a few. Are you really saying that Keysight scopes are better because a model that is comparable with the WR8K is only 20-30% more expensive? Seriously?
As the friendly representative from Keysight has noted, the 1GHz scope market is full of different options, its worth looking carefully at them all to find whats best for the specific uses, the Tek DPO7000C or DPO5000B might even get a look in.
Yes, there are quite a few 1Ghz scopes, but as always you're completely missing the point. This isn't about some 1Ghz scope, it's about a lower high-end scope in the 500Mhz to 4Ghz bandwidth bracket and a starting price in the $14k region.
You're a Lecroy fanboi, we'll call you out on this,
Who is *we*? You mean that certain other poster who just had his post deleted by a moderator for trolling? You're pretty much alone, and the only difference between you and this other poster is that your trolling attempts are more timid. The modus operandi however is the same: make wild statements, provide zero proof, and accuse the "opponent" as fanboi. Based on some of your incredible moronic statements it would probably be fair to label you as "Keysight fanboi", but I have nothing against Keysight, they make a lot of really great kit and offer tremendous service, and the last thing I want is to associate this fine company with a troll.
Anyways, it seems you're now alone in your anti-LeCroy jihad.
especially while you make up specifications for products and provide weak comparisons to try and proclaim how amazing Lecroy are.
Says the gasbag who has not provided a single shred of evidence and clearly lacks the grasp of the topic.
So unless you can provide some proof or references substantiating your claims I'll now ignore your rants and troll attempts. But I'm not holding my breath re the references, because I know full well that (like a certain other poster that shall be unnamed) you're not up for it because it's all just a lot of hot air.
I do contribute to this forum in my free time, and frankly I've already wasted too much time with shallow trolls when I could have a productive discussions with some intelligent adults instead.
Have a nice day!
