Picoscope 6 strange zoom error

Post by yym »

I have found a strange behavior when viewing data zoomed in.
Sometimes (at different zoom levels) the analog and the digital traces are not aligned, they go in and out of alignment and I am not talking about small alignment errors, they are completely off, like alignment 'jumps' >50% front or back.
See attached pictures, the data was captured in singe shot mode, then viewed in different zoom levels
z2- zoom ok (included for reference)
z3,z5 -bad zoom, whach the cursors.
Also in z5 some strange stuff appears on the digital channels (there should be nothing there )
Pico SW version is: 6.6.50.3 HW 2205MSO

To me it seems a GUI bug since the captured data is correct only it is not displayed correctly at some zoom levels.

I would like to use the latest pico sw, but unfortunately the new version doesn't work with my hw.
See this post http://www.picotech.com/support/topic11541.html

So i have to use the older version (which still doesn't work properly, but has at least pulse width trigger on channel A(only))

In order to reproduce this usecase, i need pulse width trigger, otherwise the scope would trigger on 'garbage'

Hi YYM,

The strange zoom error has been fixed in version 6.9,
but as you cannot use that version I will escalate the pulse trigger bug.
