Pajda, I implemented isolation a few months ago and have had instant and durable operation at the highest speed the AD2 is capable of by using this device:

I haven't stressed it by using it to measure across any particularly challenging reference frame differences like a circuit referenced to a high voltage or for example the high side AC line, but it does work reliably and at high speed, (not just full speed) and does provide the ground noise isolation I need in my work.  I have no connection to this company other than having bought one if these devices.

Hi @pajda

The full-speed isolator will reduce the capture rate, but in most of the use cases this is not important.

The following client had problems with expensive high-speed isolator:
