Re: Connect and control scope via computer?

Nope. It was designed to be a self contained unit. They have published the basic source code so that you could modify the code and add that functionality yourself.

Re: Extremely noisy test signal?

How are you powering the scope? My power supply added a lot of noise to the signal. When I tested it running on a 9v battery, I works perfectly. So I changed to a 9v linear power supply instead of the switch mode one I was using. The noise has gone.

Re: display

Yes. JYETech have posted previously that a screen that supports the ILI9341 controller should work, also support for the ILI9328 would be coming soon. This thread shows progress made in this area http://www.jyetech.com/forum/viewtopic.php?f=18&t=460&p=1936&hilit=larger#p1936 I don't know...

Re: Probe calibration.

Did you manage to move the little triangle on the left side all the way to the bottom? Can you post a photo when it is down, then we can see how much of the wave form is still missing. It might give a clue as to what needs adjusting.

Re: Is 12.3 volts input acceptable?

You could put 2 diodes in series with the power supply, that would drop the voltage by about 1.6v putting it safely under 12v.
Your other option is to buy a 12v to 9v, DC-DC step down module. I don't think JYE sell one but you can get them on ebay for a couple of dollars.

Moving the BNC off board?

After seeing the excellent cases that have been produced, I'm making my own. I already have my own home made bench power supply, in a distinctive shaped case. I want to put my DSO 138 in the same shaped case. To do this I have to move the screen, switches and buttons off the board and on to the face...

Re: My DSO138 Enclosure

Brilliant. Thank you. I was wondering how you got the screen close to flush with all the pin headers.

It has given me a few ideas.

Thanks

Re: My DSO138 Enclosure

That's the nicest enclosure I've seen so far. Would you post more photos and a brief outline of how you made it or what it's made of. I'm looking to make an enclosure for mine, but don't have money for 3D printing, so the more ideas the better.

Thanks for sharing the photo
