Hi,
It would be nice if one could shift the graphs of channel 1/2 up/down when a single trace has been done.
Currently, it’s only possible to shift the channels when the scope is in RUN mode.
Sometimes it’s interesting to overlay the two channels on top of each other (fully or partially, depends on the need) to see more clear the positions of slopes of both channels.

Indeed, moving the captured trace vertically on the screen may be useful in many cases. - Thank you for this idea.
The following software modifications are done:
You can download the updated version 2.04 of the PCLAB2000SE from: velleman.be/be/en/download/files/

Hi,
When in big screen mode, moving the waveform vertically apparently doesn’t work. Does only work when in “normal” screen mode.
Someone already noticed this too?

Strange problem indeed. The vertical movement should work in big screen mode too.
Do you have a special setting when the vertical movement is not working or is this problem there all the time?
Do you have the latest software version 3.03?

Seems to be the problem. Or better: the solution…
I’ve updated to version 3.03 and now I’m able to shift the waveforms also in big screen mode.
I’ve discovered another small issue with switching from normal to big screen mode, but I’ve started a new thread for this to avoid mixing too much different issues in the same thread.

A hold-off function should be very useful observing more complex signals real-time. I observe often short frames of data. Without hold-off impossible to get proper synch, the trigger starts on any internal pulse edge instead of waiting for the next frame. I have to use single, capture several frames and observe them offline. Pretty uncomfortable to hunt for changes, while it can be seen immediately online with proper synch.
One more small detail: moving a captured signal vertically can be done in fine resolution using the arrows. Moving horizontally is not so easy, moving a slider using the mouse is pretty rough. Unfortunately there is no focus nor working arrows on the horizontal shift. Either allowing the focus on the horizontal slider or dedicating the left-right arrows for the job could help.
Same for the markers (DSO).
Regards,
Thank you for your comments. An adjustable hold-off function should be useful in some cases, indeed. Sorry that it is rather impossible to implement by the software to the existing scopes.
The horizontal shift fine adjustment possibilities will be studied. If possible some modifications will be done in the next versions of the software to add fine tuning for horizontal shif.
Sorry to hear that, but I understand that hold-off function in the high speed ranges requires hw assistance.
I am EE, I use the PCSU1000 for hobby home projects, and happy with it. For the time, it did the job very well. The missing hold-off was the only problem when I seriously considered to bring home my big scope from shop for a weekend… 
I check if a crippled diy function is possible for the low speed ranges only (using the dll based development kit). Something like single shot - delay - start single shot again.
It’s nice to see that the PCSU1000 is doing most of the job well anyhow.
I hope that you get the software hold-off feature working…
The method you are going to realize it looks OK.
