Siglent SPD3303X-E Hi-Resolution Output Unlock?
optotester:
Any news regarding that issue ?
mawyatt:
No, we haven't received any response from the factory regarding this issue. Not happy with Siglent in this regard, would have at least expected a response of some kind, maybe not favorable, but at least a response.
Best,

I finally ended up liberating mine now, and it's working great! :-+
I was a bit worried since I read posts about people losing calibration, serial number, and the mac address in different attempts.
But I noted down the serial and mac just in case and went for it (using tv84s instructions).
From reading other experiences, SCPI should have returned the full resolution even before the upgrade, but it did not. Both before FACTORY ON, and after, it was only 10mA resolution. Perhaps they changed that in the latest firmware, which is where I upgraded from. The additional digit did display on the device and with SCPI after the upgrade, so I'm satisfied. It's really nice to have 1mA resolution on current measurement.
There are a few mV difference between "set" voltage and "read" voltage (like others have noted), but the "read" voltage agrees pretty well with my multimeter, so that's fine.

It appears there is a new HW revision (6.0) of the SPD3303 which requires minimum the 3.10 firmware (V1.01.01.03.10).
As that the conversion is no longer possible with the old patched firmware - this would require 3.10 to be patched.
As the side note: according to the release notes the newest firmware (3.10) is not for older revisions of the SPD3303 as it requires HW 6.0+.

Don't remember about what patch you're referring to. But, if you're talking about a conversion patch, you don't need any more patches. Once converted, you can flash the new stock FW.
