Welcome
I use NaioAFM from Nanosurf company. please how I can get a solution for the background noise (electronic noise) during measurement.
PID parameters are
I 1000
P 1000
D 0
Scan rate 1 sec/line
1) 1Hz scan rate may be a bit much for an image with dimensions in the double um digits.
2) Have you tried varying the amplitude setpoint?
The disturbances looks like 50Hz from line. You may try to use a isolation transformer. We made yood experience in using reducing 50Hz noise.
Hello & have a nice day!
You can use Gwyddion software to work with raw AFM data. This software has the widest possibilities, including where it is possible to provide a low and high pass filter using Fourier transform.

Kirsten Ingolf Schiffmann I using on-line power supply (UPS), please where I can get the best isolation transformer suitable for my work?
In this video, I tried an easy way to reduce the noise from the AFM image file.
I hope it is helpful for you
