Is it true that oversampling helps? #22

Testing this at TENSS, it doesn't seem to. However, in Basel it definitely helped with ScanImage. So either ScanImage is doing things differently or something else is different. Maybe it's due to the faster Femtos used in Basel compared to the Standford amps here at TENSS?

yes: https://raw.githubusercontent.com/tenss/SimpleMScanner/gh-pages/images/samples_per_pix_example.jpg

But you won't see the effect if the amplifier bandwidth is lower than the your DAQ bandwidth. Essentially you are then averaging the analog signal.
