Hi everyone.
Is there any reason why an (almost new) oscilloscope in AC coupling mode shows a small offset (a couple of milli volts)?
Example (using 1x probe):
Is this normal for relatively cheap new oscillosopes?
I didn't realize this behaviour with anolog scopes.
The offset spoils the (AC) RMS measurements, as it takes into account a mean value, and it is annoying.
Thank you!
