Hi I bought what I thought was a DSO nano but got a DS201 unit and it looks like it is not the same - to start with there is no signal generator ? Should there be one ?
My model has white buttons and is made by mini dso - this is a website in Chinese and there I can’t do anything. The manual is idiotic and directs me to that website.
When turn it on I get some ‘reference’ magenta permanent waveform that keeps coming back. I connected the probes to a DC powersupply - hoping to measure how noisy it is - whatever I do I can not get a meaningful waveform to show.
When I turn it on it says version 4.21 - should I change it - none of the links I found for upgrade work - where is the correct one ?
Is there a way to even try if it works at all ?
