Pico 4444 inacurate data logged by Labview

Post by Taba »

Hello! I'm trying to get data from my PicoScope 4444 using Labview and I'm getting this
LW.png
instead of this
PS6.png
Look at those slopes of the lines that should be horizontal on the 1st image I've got in labview and how that same graph look in PicoScope 6 software. What could cause these slopes in LW?
I've tryed to turn all the knobs and buttons in Labview (like resolution, timebase, down-sample mode etc) with no success.

We would need to see how you have setup the scope in LabVIEW, and additionally a psdata file for the PicoScope screenshot would help.

Slopes in waveforms can be due to using AC coupling caused by the blocking caps charging up.
