Are there any hacks for Siglent 3303x-e power supply?

[n3mmr]

I thought I saw a mention of a hack for the FW of the Siglent 3303X-E power supply to enable 1mV set and readout accuracy, or at least 1mV resolution.

Does such a hack actually exist?

Sure does, tv84 linked it. 

Even for the X-E model, 1mV and 1mA resolution is available within the EasyPower software.

Hallo siglent users

I hacked my new Siglent SPD3303X-E in to SiglenSPD3303X . I am verry happy 

Its verry easy:

First installed EasyPower from Siglent on my Win10 System

Then I install NI-VISA from National Instruments

Than start EasyPower

After that connect a LAN or USB cable

Press Connect symbol under Menu "File" and set in EasyPower 0.001V CH1 (press "Set)

Now press menu "Version"  > "Upgrade" > "Normal Mode" > "UpgradeFile" and load firmware file "SPD3303X-1.01.01.02.05_ConvertFromX-E" and press "Upgrade" and  wait a little bit to upgrade file (see a blue line on LCD screen to Siglent power supply). After this press ok and the Power Supply restart automatically.

It is very simple and nice. Thanks a lot

Thank you for the instructions.  Worked fine on a new SPD3303X-E.

Yeah worked on my too. On a 500kcnt DMM, it tracks well. I have never really load tested it, at least not since I have the 1mV/1mA resolution.

It's pretty quiet, it's my 1st and only PSU, but compared to any wall powered device I've had on the scope, it looks very quiet, at low power anyways.

Just did it with a 3303X-E, bought in December.
Works without problems.
PS answers correct S/N to "IDN?" on command line, leaving possible Siglent database entries or the front sticker mismatch. I can live with that. 

Thanks a lot guys!
