It seems to be working with a 9V battery.
My power supply (240V AC -> 9V DC) supply approx. 9.8V and ist quite linear (measured with the DSO).
What PS you are recomending?
Where to get this?
Trace only works at 5V/div
Re: Trace only works at 5V/div
Portable linear PS is not common nowadays. Most power supplies you see are switching mode. Just looking for better quality switching mode PS. Most of them are okay for DSO Shell.

With a 9V battery it works.
What are the boundery conditions for a 240->9V PS?
That one what I am using the noise is quite low, so I don´t understand why it´s not working with this.
