My biggest grieve is the limited count of only 1000 max. for the measurement statistics. This means you cannot have a long-term average and – even worse – not run some experiment for hours and then determine the correct min/max values for some measurements for the entire timespan.
Yes you are absolutely correct.

+1, "Coffe break" workaround from software dev perspective would be disable 1000 max check or move it up to some ridiculous number. Better two options: unlimited; limited to x. Better still personal limit override possibility for each different measurement. Also it badly needs [reset] button (not Run|Stop capture like now!). Better still possibility to reset each measurement individually. Also column auto-width should work better or need possibility to manually scale. I'd suggest to apply relentless pressure thru their support forum or directly to support to get such 1 day programming jobs nearer to the top of priority list.

Another example:
https://www.picotech.com/support/topic27711.html
integral(derivative(X)) does not work. If anyone cares - tell them. I'm waiting for 2 years already. If wondering whats the point of this - it's basic integrity check. If this works then several of the other bugs and "cannot do's" around time shifted traces, or traces with different record lengths will "fix themselves".

Done, one evening work, despite had to learn Python in progress... Long term stats: Update rate ~1Hz. Arb decimal places. Full auto sync with in-GUI measurements (Add, Remove). Feeds real time on little known "human readable" CLI interface that is quite nasty to parse.

Not everyone who knows how to upload a video is automatically qualified to review modern T&M gear.

I have 3 PicoScopes for private use (2 x 3000 series, 1 x 4000 series) and for professional use I have made sure my whole R&D department got equipped with PicoScope 3000 series MSO. You bet if there were any serious issues with these instruments, I would know it.


Please, be so kind and upload a video that proofs that you are right.
Or are you not able to do so?

PicoTech has thousands of PicoScopes, but obviously did not know that ROLL Mode and ALTERNATE Trigger is compulsory for serious measurements.
But I read in another forum, they will add it.

Thousands of Diesel-drivers did not know they cars were manipulated.
And if you believe the CEOs, they did not know either.

I guess you did not know anything even if you had three hundred.

Rohde & Schwarz, Tektronix, Keysight etc. - they all have Roll mode and alternate trigger though some manufacturers use different names for it. Guess why they have it? Because nobody needs it, right?

Even Peaktech and crappy Hantek has alternate trigger.

Ok, if you only want to see the output of the signal generator on one channel, it is redundant, but other people want to measure some more things.

Oh armes Österreich.  :-DD

What PicoScope oscilloscope and what PicoScope Software did you use ?

Got it.

This is AUTOMOTIVE SOFTWARE !  Does NOT work with PICOSCOPE 5444D MSO.

Stop kidding us  or  learn reading posts.

So far all YOU proved to us is that your bedside manners could do with an improvement  and that you might like improper nationalist statements-...

Picoscope has alternate trigger by using logic trigger.. It's in a manual, but that require actually reading manual. It is easier to just mouth off random statements.
And, I very rarely use alternate trigger in my work. Pretty much I can't remember when was the last time I used it.
If it really wasn't there I wouldn't care. It is hardly PREREQUISITE to profesional work in mixed signal environments.
Most of the time I want as many signals as I can correlated to common clock or something...

Normal Picoscope software doesn't have Roll mode in a menu...
But what MrW0lf showed you (if you payed attention) was that if you are in a scan mode (slow scan) and you take trigger and drag it to top right corner of screen, it WILL behave as if in a ROLL mode.
And that works in a normal and  automotive version of software.
I have confirmed that for my 3406D MSO.

So, it might not have those capabilities in a menu, but it has them. If you know how to use it.
And it would be wise to listen to wise man that do this for a living and that are Picoscope users for years. You might learn something from them.  Even from a guy from Austria, Croatia or Estonia....
Just ask, nicely...

Mit freundlichen Grüßen,

Sinisa

You take people for fool.

Those settings are ridiculous jugglery, but it ain´t roll mode.

Show the complete video from the very beginning and people will know it is jugglery.
Change the waveform (from sine to square or whatever you want to) or the time base setting during operation using your weird settings and you will notice, too, that that is not roll mode.  :palm:

PicoTechnology confirmed, there is no roll mode and no alternate trigger.

Either you don´t have the slighest idea what roll mode and alternate triggers mean or you are selling Picoscopes.

I do not expect you vendors to know how real engineers measure but I expect everyone to keep his mouth shut if he does not have the slighest idea of what he is talking about and mistakes apples for oranges.

Your dumb theatre show is just shameful and embarrassing.
It is useless to talk with dumb and unteachable folks / vendors about real technology.

They do not know their software as well as some... :P
What source did you use when saw funny stuff - internal generator?

Change the waveform (from sine to square or whatever you want to)
