content: Quote from: Gregory on July 13, 2020, 06:50:17 amYes and you should be grateful that you have it.Try measuring rise time of a signal with non monotonic edge, and then tell us how would you know which part of edge did algorithm chose to do measurement..There are many measurements that you want to make sure what exactly scope is measuring, which part of the signal. It is a visual verification that you are measuring the right thing.I wouldn't buy a scope without it...I agree that shutting cursors off shouldn't hide measurements. That is crazy..Like you said, it doesn't do that on 3000T.Did you try putting cursors in manual mode and the shutting them off ?

content: QuoteYep.. I understand that.QuoteDoes not work.When entering the cursor menu, it replaces the measure stack with cursors info. When pressing cursor again to disable, it clean the panel and the measures get turned off.If I press Meas again to take the measures back on, the automatic cursors appear againThis thing aways on is really more annoying than usefull..

content: Can confirm this is intentional (love it or hate it). The goal is to be as clear as possible about what specifically is being measured.

content: Quote from: Keysight DanielBogdanoff on July 13, 2020, 08:41:10 pmWhat !?Why I can`t disable it ? Why touch version can ?I have the scope for 9 year now and I realized just recently how annoying it is.I really think it`s a bug in the 3000 firmware. As others said, they can disable it !!

content: Quote from: Keysight DanielBogdanoff on July 13, 2020, 08:41:10 pmIntentional??? The user can not disable it because it must be as clear as possible, but only for DSOX3000A users and not for DSOX3000T users?Give me a break...

content: You are talking to a Keysight engineer from their scope division. If he says it was intentional you better believe him.

content: While I understand that you should be able to disable it if you don't want it, you are blowing it WAY out of proportion...I had to go check on my 3000T if I can shut it off, I always keep it on.You, by your own testament, had the scope for 7 years, and just recently realized you can't shut it off..So, obviously it is not a real problem, if it took you7 years to realizeit's there..As I said, I also think that you should have a way of disabling it, just because you want control of it.But realistically, you are almost hysterical to make problem where there isn't one. Get a grip.Daniel is a very nice gentleman that helped many members here, with real problems (like brokens scopes, or vendors refusing warranty.). Hedeservesa polite tone, heearnedit,manytimes.For this minor niggle that bothers so very little people, you should very politely ask, and if it is possible, Keysight sometimes makes some things at user requests. Or not, if they have to release whole new firmware just because of this minor discomfort of very few...Please don't take this as an attack at you. It is not. You are a new member (40 posts) so you deserve to be helped to acclimate to forum, it's way and etiquette.. And I'm kinda direct and don't like dancing around the bush. I just tell it straight.So, welcome here, please go slow with drama until you get a grip what is and what isn't appropriate and I hope you like it here..Regards

It may be no problem for you and many others, but it can be annoying for some. I don't know where you found that problem bother "very little people", "very few...", maybe your affirmation is because it doesn't bothers you, or that you have not seen it mentioned before. And something annoying in your daily work tool is disgusting. To me yes, it is a problem. And as pointed above, other models allow turn it off.I agree that Daniel is a nice gentleman, but we can disagree with him. We are in a forum with many different user experiences, opinions, preferences, and so on. No one here are disrespectful with him, that yes would be unacceptable. I, for one, do not buy his answer saying that it is a feature (intentional) when in another Keysight series it is allowed to disable it.Another point is that if the OP is a new member or not, it has no significance at all, in fact the OP is a older member here (since March 2013).As pointed before in other threads, it seems that some brands can not be questioned. Bugs becomes features...

content: Quote from: rodpp on July 14, 2020, 06:33:11 pmHehe, you're barking up the wrong tree..I don't play preferences.. It's mine hard earned money I buy this stuff with. I take no crap from anybody, ESPECIALLY Keysight or other A brands, because i expect perfection from them, for the kind of money they charge.And believe it or not, in mass produced product, many outnumbers few. Development costs real money, and is put towards real capability, not some details only few think are problems. If Keysight got several thousands complaints about this it would be changed many years ago.Other models are actually based on completely different code base (3000T/4000/6000 share platform) and it is there by code modularization because of touch screen interface. 3000T still automatically enables cursors when you add measurements, and by default cursors are there so standard behaviour is the same.And I disagree with Daniel. I participated in topics about options updates and bugs in Keysight scopes. I'm sure Keysight wasn't glad about what I proposed there and what I think what they should do. But make sure that you know the difference between Daniel, the person, and Keysight, company he works for..And about this particular thing, yes I don't think it's a problem.By OP own statement "I have the scope for 9 year now and I realized just recently how annoying it is."... really... It is really hard to take that statement seriously, really....And op has 40 something posts.. Makes him a person that is not active here, new or not. I don't make background checks on members, so between low post count and posts that are a bit off in etiquette here, I presumed he was new. I was wrong, thank you for setting me straight. I'm not sure how is that relevant though and that it makes any difference to the topic.You cannot decide that some manufacturer's design decision is bug because you say so.I would like that my scope had more memory. Surely it is a bug, I demand they fix it.. It doesn't work that way.
