Thanks. I am curious if on 3064E scope (8 bit) they use HMCAD1511 or use HMCAD1520  and limit it to 8 bit in firmware. I think it's chip U45.

Here is a photo of the chip on my XDS2102A.
It says HAD1520.

For reference, here is another plug for Owon scopes. I was testing Owon XDS3062A directly against Rigol DHO1074 and it came out ahead in high dynamic range. In this plot, I can resolve the phase noise of HP 3326A synthesizer using Owon oscilloscope, but not using Rigol's DHO series. So the old HMCAD1520 chip is holding up well. It doesn't have very high sample rate, but for low frequency work seems quite good.

Dear fellow Owon XDS users!

I can contribute the shots of my XDS3064E internals.
I had to pull the MoBo out of my scope in order to ship it back to factory for warranty repair.
Sorry that I did not take better closeups of the front-end...
I suspect the repair must have consisted of some sort of reflashing or software fix, as I see no signs of any interventions to PCB.
The support person also told me that they are not in a position to replace the MoBo as a unit, so I shall send mine in for repair.

Last but not least - how do you guys charge the battery pack for this scope?
First time it broke down with a no-start condition after 8 months of usage.
I had left it connected to AC power, in turned off state, to recharge the battery.
After some 4 hours of charging, the oscilloscope did not start! Now, just 3 days ago, about a year after I got it repaired in warranty, it happened again!
I can see the splash screen, but after that it turns off.
Only the RUN/STOP button lights up in red, no others have the green light, as they should.
It is very disturbing, that the battery charging can break the whole oscilloscope.
I think it should not be used with the battery at all. Otherwise there is constant risk of having this non-start condition with this device.
Or should I charge the battery only in the powered on state of the scope?

PS Lucky me, I got it back into running state, with the firmware flasher I was sent by support tech the first time. Back then it did not help, hence I was asked to send the MoBo in.

Hello there!
It seems I have the same issue, may I ask you to send me the flasher utility?
