Siglent SPD3303D review
mimmus78:
Prematurely wear out? Not at all, I have others Agilent power supply and almost never used this Siglent one.
When he developed the problem was almost like new ... Now I learned to turn off the channel before changing voltage, but this is not always possible.
Anyway it should be a safety (for the circuit you are working on) to not ever jump like this. It doesn't even have acceleration implemented ...
It also has the USB tmc bug that was never solved. You get what you pay for.

I tried the firmware update on advice from Siglent after having front panel lockups. It is under warranty, and Trio are fantastic, sending me a loaner while mine is being fixed, but would like to recover it if it is straight forward.

IIRC, you put it in the bootloader mode by holding the rotary encoder pressed while powering up. Then you'll have to choose "bootloader mode" in the supplied software while uploading the firmware file.

Thanks, that worked. I also had to reinstall the NI-VISA drivers, mine had gotten corrupted somehow. FYI, don't do the update via a USB hub, or you may brick it. Direct connection worked. Now I can wait and see if the update fixed my panel lockups!

I'm sure anyone who cares has already figured it out, but it's quite trivial to upgrade the 3303D to the S version. Simply open the S version .ugf file in a hex editor (or maybe notepad) and change the 'SPD3303S' header to 'SPD3303D'. (EDIT: Ooops, I had that the other way around... :-//)
Of greater interest is upgrading the S version to the X version firmware. After comparing some pictures, it looks like the D/S controller board is very similar to the X/X-E one. A quick look at the .ads format firmware for the X version suggests that it is indeed built on the same foundation as the D/S firmware, with 3303D and 3303S strings still intact. Unfortunately, the .ads format for the power supplies is not quite the same as the one used for the oscilloscopes, so more reversing is needed. Refer to this thread for more info: https://www.eevblog.com/forum/testgear/siglent-ads-firmware-file-format/
As always, we would very much appreciate it if Siglent could simply backport some of the interface improvements to the 3303D/S and save us all a load of trouble. :-DD

Not worth the effort as the X series PSU's use a LCD display vs LED for the old models.
My 2c is go for the later SPD3303X-E. They're the only ones I stock now.....so much more info on the home screen:
