As early as last year, we have fixed this problem, please rest assured purchase.

Thanks. In which hardware version was it fixed, if someone wants to verify it? When I click on the version button on my device, it shows "hardware version V1.1".

Siglent:
the hardware is still V1.1, but we have corrected the mother board version.  the Prior version is SDY8.007.038D, now it has been modified to SDY8.007.038E ( as the figure showed)

ScottyAU:
My Siglent arrived today.  Bit hesitant to open it up just yet to check the board  ;) Display says Software 1.01.01.01.06 Hardware V1.1

I've hooked it up to the scope and done a few tests (screens below).  All tests done on the 3rd connector set to 5v with a load resistor across the 3rd output.

1) Cold power on
2) Shorting the 3rd connector
3) Removing the short on the 3rd connector

Be interested in peoples thoughts...

jimjam:
Is that a 1V - 1.5V spike on power on?
