Questions in an endless stream from this newbie scope user.
There's a document on the Pico website stating that the effective resolution of the 12bit 3224 can be increased to 16bit on some signals by using oversampling.
How is that possible?
I thought that the analog to digital chip had a fixed 12bit resolution and it would seem to me that is the absolut limit for how low a signal that can be seen on the tinput of the chip.
Or is it so, that the actual ADC has more than 12bit but are limited by overall noise in the scope circuits, and by averaging the noise can be supressed and hence a higher effecdtive resolution?
Please help me to shed some light on thios issue.
