Hi,
I am in my second year of Electrical Engineering and I have just received my first proper scope. A Hantek DSO5072P (I also have a Pokit
https://pokitmeter.com/)
Today I have been playing around with it and the Pokit by looking at a 0.5kHz square wave generated by a Raspberry Pi 3B+.

This is what they have shown
The Hantek:

The Pokit:

I have also included the excel files that I got from the csv files that both have given me.
What I find strange is that the Hantek peaks at 3.7V while the Pokit peaks at a more reasonable 3.37V. Both show a steady state at 3.3V
Both are DC coupled, in their normal mode, the Hantek has been calibrated, the Pokit is the 1MSps version, and I have kept their leads as straight as possible.
My question is there a way to fix the Hantek, should I return it, or is the Pokit lying to me and this 0.4V spike is normal?
