Using USB cable supplied with the device for power. not using a battery yet.
power supplied via a 5V USB power supply.
All voltage test pass, +5v under JP4 on the board shows 5V.

DSO068 Working. Adj dial and btns work after reset

DSO068 Working 100% now the Adj dial and buttons wont work
I have had the completed unit working and everything seems to work fine for the last 2 weeks. Originally I had a problem with the crystal not working, straight out the box! I replaced it with a higher freq one I had laying around. everything worked nicely until yesterday I noticed that the Adj dial ...

Re: DSO068 LED wont Blink Replaced Y1 and C21,C22
The crystal oscillator was faulty right out the box, I managed to pick up a pack of 32.768KHz. I could not find an exact match on the websites I checked (at least with reasonable shipping time) for a replacement for the 20MHz crystal that came with the scope. Anycase I got the scope to work. all vol...

Re: NEW DSO138 Mini no trace
Thanks for all tips and the feedback, Nationwide. As it turns out my original problem had nothing to do with the power. My problem was actually fixed by replacing choke L1. After much testing I can confirm that the NEW DSO138 Mini, requires power to be supplied via the USB (5v) input port on the scr...

Re: NEW DSO138 Mini no trace
Thank you for the advice. The scope works well with L2 shorted. The choke was defective, right out the box.. so much for Q.C. label on the box (sorry to say, someone dropped the ball). I searched the web to try find a choke, with no luck. I was gonna leave it L2 shorted as the scope seems to work fi...
