Dear Amy.
Thank you very much for your message,
We have new problemn with this scope ,one of our engineers was working with it at a customer location in another city and he was working seriouly
the scope was connceted to the USB for around 4Hours when it stopped to work ,

(1)Pluging the scope into a the PC always result in that windows does  not recognise the scope (note it was working alwways on this PC so drivers are good) .Also no Red Led coming ON

as you see here
           
I then installed the drivers new on another PC and that still shows unknown device

The Engineer told me that the scope was not hot but had normal temperature as it was working for 4 hours (connected tp USB)
I opend the scope and I do not see any burned componets , as shown on the pictures


            

I also tried to connect with the FPGA update tool to connect to the scope the tools reports " No device was found".


        
It looks to me one of the following
1 - USB chip broken
2 - FPGA is broken
3 Power supply 3.3V is broken

is there away you can help me solve the problem as to send the scope to the factory for repairs cost more that another scope and secondly take a long time
Thank you so much

Sorry, our engineer is solving this problem. Please wait for some times.

Dear Team,

Please can you give some indication to what the issue can be as there is no documentation(manual) for using the SW it hard to understand what to do
this issue is now long time in discussion can we please solve this or tell us that it not working and you will not fix it ,then we buy a new scope from another manufacturer and I do not waste
your time and you do not waste my time

Thank you

Dear Amy.
Thank you this is working in the scope window it shows the correct hex values
However the data in the Table view is incorrcet regardles of the trigger slope (+ or- ) is always shows 7F 80 which as you will notice in the scope
window it is correct B7 BB ,

Can you help me understand how to use the table correctly as if we send a transaction of a number of bytes it is prefered to see the transaction in the Table view
secondly what is the function of the hex control ?
Thank you for all the support I have received from you.

The unit of overtime should be ns, and the software does not show it. Please set the overtime to be greater than or equal to the clock period. Such as 3000ns.

I am sorry that I send you and email

Refer this to update the FPGA software.



Both the data channel and the clock channel use the same trigger level. Please make the two channels in the same position to try.
