yes, I guess I have no option but to buy the 400usd original component. Anyways, thanks a lot for posting and sharing this project. It's super useful!

Hello Guys,
I have built and tested a few couples of samples of my design 3.0. Everything works fine. Find attached some pictures

and here some more..

Is there a link for the v3.0 PCB and BoM?

Cheers!

I just bought the original chip, From China , let wait to arrive

Original CHIP or Rigol probe for $400?
If there is a probe, then you will have beautiful wires.

I was offended to buy it for half the price of an oscilloscope, and I also regretted the money.

I'm talking about the Ti Chip

Hi,
Can I use it for my ds1104z plus oscilloscope?
I think my oscilloscope and yours using the same device

Thanks

Yes, but you need to take care of the connecting wire to the other connector.

raminrajabi · « **Reply #109 on:** July 20, 2022, 05:29:26 am »

I think both oscilloscope using the same module, so same connection? Right?

For those who are looking for sn65lvds1dbvr - https://aliexpress.com/wholesale?SearchText=sn65lvds1dbvr

But I already bough 6 x sn65lvds391

, so will make my board with it...

And not only oscilloscopes.

This is a common LVDS interface, widely used.

Perconally I can't help you - all logistics from Russia to Europe has been destroyed.
But you can order PCB and assembly on JLCPCB or PCBWay, for example. It's not difficult.

Hey guys,

I built a version of this DIY LA.
My scope doesn't recognize, when I plug it in.
The outputs of the DS90.. are fine, but the scope indicates a constant low level.
Any advice?

How did you check the LVDS outputs? This is a differential signal, it does not need to be measured relative to gnd, it is the voltage between pins 3 and 4 that is needed. It should change when applying 1 to pin 5.
If this does not happen, the power supply may not be supplied or the chips are faulty.

And it is absolutely necessary to check the flat cable - whether it is properly compressed (it should be 1:1, pin to pin, the keys on both connectors should be in the same position), there is contact on all wires.

Did you remember to turn on LA in the oscilloscope?

This is a very simple circuit, I'm sure you'll find the fault.

S.P,
just a quick question, how did you generate the board view for this project? i have been using altium to generate PCB files and have not seen a board view quite like that.. very handy for loading a board manually. i searched easyeda's wiki and didn't see anything..

To get BoardView and a few other very nice features in EasyEDA, you need to install pragins.

Altium is too expensive and cumbersome thing, I don't use it.

mrpea · « **Reply #118 on:** November 08, 2022, 10:12:43 pm »

Thanks for that.. I have been using Altium for the past 15 years, i have tried to use EasyEDA and KiKad, but i keep trying to use the fast keys for Altium.. i really need to do a full project in either to become more proficient.

You can import a project from Altium into EasyEDA and generate a BoardView.

Hi,

What voltage should be measured on the unloaded ProbeDet pin?

Approximately 3.3-5 volts.

imolnar · « **Reply #122 on:** January 12, 2023, 12:13:16 pm »

0.4V by me.

0.58V
If short this pin to GND, "Probe connected" message will show about 3 seconds.

imolnar · « **Reply #124 on:** January 12, 2023, 12:54:49 pm »

There are no messages on my scope. I can press the LA button, but there is no change in the digit channels.
