Looks a nice scope!
I’ve had a DS1054Z for a few years (upgraded to 100 Mhz).
Now that the firmware revisions have settled, I find it works fine for whenever I need to use one (Analogue). If you get one cheap with all the probes then I think most would be fine with it.
“Are there any other cheap options for SW debug - e.g GPIO, SPI,I2C,UART and limited Analog capability.”
Hi Mirtcho - For digital signal processing, I find this works a lot better (don’t get the 8 channel one - it doesn’t buffer the USB as much)
