Hi, i have that problem. When i want to read a AC signal in an audio amplifier with the channel setting AC coupling, the software shows me a DC signal of 20V. In that test point i have much more DC signal than that but it has to be 0Vac, because im not putting a signal in there. Anyone can help me, why the PicoScope or the software are reading like 20Vdc? Thank you very much.
Adrian.
Hi, i see that this is not the correct place to put this. This is the automotive section, sorry fot that. Anywhere i have the PicoScope 2000 series and the level zero signal adjusted to 0V. When i measure in AC thats what happend : https://imgur.com/a/eMocO

Please can you email in to support@picotech.com we need to discuss what you are doing in more detail, and the automotive forum is not the correct place for this.
