DSO Nano V3 purple Data trace & saving files?

Post by gratefulfrog » Mon Jun 17, 2013 5:23 pm

Hi,

I just got a DSO NANO V3 with all factory setup and firmware. I don't know how to tell which firmware it is...

I think the little device is pretty cool and value for money, but I have a couple of issues that I can't seem to work out from the so-called "manual".

Could anyone please tell me:
  • how to get rid of the purple DATA trace (looks like a decaying sin wave) ?
  • how to save and load data, images, i.e. how to record a trace to memory?
  • where to get other firmware that may work better than what is on board?
Thanks for your help.
Ciao,
Bob

It is the DATA trace that is stored and I cannot make it go away!

Please help !

Thanks,

Hello!

I am still waiting for help removing the purple data trace from the screen!

Please help me, I do not want to have to complain any more or return it to the shop and tell the world that it doesn't work...

Your technical support is really disappointing...

Unless I hear something soon, I will be posting on all the associated Arduino forums to tell about this defect and bad support.

Ciao,
Bob

Can you scroll down to setting ex and use your left and right arrows or is it stuck there.

I can make it move up and down a little, but I want it off .

Why would I want to see that trace? It is just annoyance for me.

If it is there for a reason, then why do no other oscilloscopes have it?

Come on, just make a new firmware release that is fixed, please?

What do you mean "set it to off". Can you make the purple trace go away? even temporarily? How?

I find this tool really not great. Even for the low price, I'm regretting buying it...

Do you find the plugs connections not being very stable? I find that jiggling the input jack can really change the waveform....
