Yes, but with a simple AWG, and the hardware user interface added to it. For the rest the same crappy front end, same FPGA, ADC's and MCU.

Well thank you for the info this has been very interesting.

Now do i read it right when i see that the ADC's being used in these scopes are only rated for 200MS/s and not 1GS/s as advertised?
200 megasamples per second VS advertised 1 gigasamples per second that is.

Hi George,

yes that is the right file, but in the command you types you forgot the "dd". You used "sudo if=......" instead of "sudo dd if=......"


--- Code: ---sudo dd if=fnirsi_1013d_fwb.bin of=/dev/sdb bs=1024 seek=8
--- End code ---

Try the copy and paste method I wrote about before :)

Good day,
Peter

A single ADC is only rated for 100MSa/s, but with two ADC's in a single package you get 200MSa/s by using different clock phases for each ADC. (180 degree phase shift)

All the information about the scope and the reverse engineering process can be found in this thread https://www.eevblog.com/forum/testgear/fnirsi-1013d-100mhz-tablet-oscilloscope/

Well Peter, you're not gonna believe this! it's up and running. My firmware must have been trashed after all. When I switched on there was lots of relay clicking. I put my probe in and hey presto it seems fine. I do notice that there is a slight screen shimmer.
Also i see under the battery icon it says v0.005 is that revision or volts?

Do we now have the latest firmware fix installed ?

Couple of pics to show are attached. I don't know what all the bother was about (he he) I must hold the record for the slowest installation of your firmware.
Thanks, a big bunch Peter, you'll get your thanks in heaven.

Best regards
George
