content: 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?

content: Quote from: n3mmr on February 17, 2019, 12:20:09 pmSure does, tv84 linked it.Even for the X-E model, 1mV and 1mA resolution is available within the EasyPower software.

content: Hallo siglent usersI hacked my new Siglent SPD3303X-E in to SiglenSPD3303X . I am verry happyIts verry easy:First installed EasyPower from Siglent on my Win10 SystemThen I install NI-VISA from National InstrumentsThan start EasyPowerAfter that connect a LAN or USB cablePress 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 lotMy Siglent SPD3303X-E with 1mV and 1mAGreetings from germany. Rolf

content: 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.

content: 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!

I think i went about it in a slightly different way to others (or i didn't see it being mentioned)setup easypower and test connectionsdownloaded the SPD3303X_V1.01.01.02.07R2 firmwareit's easypower that decides if the firmware is the correct version for the device , so i ran it in the debugger, set a breakpoint at the check of the IDN? which is basically right before it says "This file does not match the device!" and set the IP to jump past the check ( swap the jz to a jnz) and continued the update.Code:0x0434B4D 0F BE 4D 0C movsx ecx, [ebp+arg_4]0x0434B51 3B C1 cmp eax, ecx0x0434B53 0F 84 A4 00 00 00 jz loc_434BFD <<----- change this to jnz or just set the IP to the target location0x0434B59 0F BE 55 0C movsx edx, [ebp+arg_4]0x0434B5D 83 FA FF cmp edx, 0FFFFFFFFh0x0434B60 0F 84 97 00 00 00 jz loc_434BFD0x0434B66 6A 00 push 00x0434B68 6A 00 push 00x0434B6A 68 44 82 4F 00 push offset aThisFileDoesNo ; "This file does not match the device!"no firmware mods were necessary.IDN?Technologies,SPD3303X,SPD3XIDD4R5442,1.01.01.02.07R2,V3.0cheers,charlie

content: yep this needs no mods to any of the software, just the flow.also there are other models listed in there, so might work for others too that are similar situations. the actual firmware update is just a couple of commands and they send over the firmware chunk at a time via visa and UPGRADE1

It now thinks it's a Siglent and the serial number has changed.

content: It was an .ADS file from tv84's .zip file inhttps://www.eevblog.com/forum/testgear/siglent-ads-firmware-file-format/msg1830584/#msg1830584that worked, eventually.The wasn't any difference in how I went about it from the other attempts, all I would say is I had to close the app a couple of times using the task manager when it hung.The calibration does not appear to have been affected, it tracks perfectly (well within the combined specs) against my Keithley 2000 on both voltage and current.

content: I got an SPD3303X-E yesterday and converted it to the X version based on the posts in this thread. The updated back to the latest X firmware from the Siglent site. (1.01.01.02.07R2)Interesting thing happened. The MAC address is now set to ff:ff:ff:ff:ff:ff and will not get a DHCP address any longer (of course). I can assign a static IP and everything works as expected.Wondering if anyone has seen this.

content: I just unlocked using the check bypass method and I kept my MAC address/serial number so it seems safer. You do not need a debugger by the way. The exe is not compressed so you can directly edit it with an hex editor like HxD.1 - Open EasyPower.exe with an hex editor and look for 0F BE 55 0C (there is only one occurence)2 - Just before that occurence, replace 0F 84 A4 00 00 00 by 0F 85 A4 00 00 003 - Flash the firmware using the new "no check version" of EasyPower you just created

content: Hopefully it is alright to dredge up an old topic. I wanted to save someone some time and/or heartache.I purchased a SPD3303X-E that arrived with hardware version V6.1 and software version V1.01.01.03.10. I didn't pay too much attention to thisand tried tv84's procedure from the original link in this thread. EasyPower warned me that the firmware did not match, which I should have heeded but am too stupid to quit. I performed the EasyPower hex edit and forced the firmware update and was met with a dead unit.During my panic searching and self-loathing, I couldn't find any recovery instructions. I figured Siglent had some sort of bootloader or firmware update methodology, and held all the buttons while powering it up. Found that holding the adjust knob in while powering on boots to the firmware load screen, huzzah!Firmware Recovery Steps (Hardware V6.1)Download SPD3303X-E V1.01.01.03.10 ADS from SiglentPower offHold adjust knob inPower on. Device should boot in firmware mode.Start EasyPower -> Version -> UpgradeChoose firmware mode and select the SPD3303X-E V1.01.01.03.10 firmware**Note: I used the hex-edited EasyPower exe for this, but should work without itWhile researching, I found that hardware V6.1 was incompatible with the previous (V1.01.01.02.yy) versions of the firmware, which was likely causing the issue.After getting through all that, I was able to send the SDS3303X OS using the hex edited EasyPower. Doing this removed my cal coefficients, so I calibrated the unit usinghttps://www.eevblog.com/forum/testgear/siglent-sds3303x(-e)-calibration-fw1-01-01-02-07r2-best-practice/and it's working like a clock!Hope this helps, and thanks to everyone for the great tools and documentation.

content: Glad you succeed! My 3303X-E will just boot into the firmware upgrade state after I directly upload the firmware of 3303X into it using the modified easypower.exe. Did I miss something?-edit:I didn't read the Release Notes first. It stated that: "B. < V6.1 hardware version of SPD3303X/X-E do not support upgrading to this version (SPD3303X_V1.01.01.03.10.ADS)". The result was the PSU will boot into the firmware update screen after reboot.

content: Thank you, My Hardware version was V3.0. I am trying to get NI MAX to recognize my PSU but so far I had no luck. I have both the USB and LAN connected, NI MAX can see a USB VISA device but can not do a thing, and it can't see the PSU on LAN although easypower can. Maybe I missed a driver or something?-Edit:I installed labview with NI package manager and now I can connect to the PSU with LAN. Maybe something needed was installed along side the labview.

content: Quote from: akkk44 on August 08, 2023, 01:21:38 amQuite likely.If you download the free EasyPower SW and read the install instructions, it requires NIVISA Runtime at the least (smaller package than NIVISA full install) for the connectivity drivers.https://int.siglent.com/upload_file/zip/software/Power_Supply/EasyPower_1.01.01.18.zipWhat is your PC OS ?Some think they know best and install the incorrect driver especially for USB and that needs be removed and the correct one linked to the device.Files attached for guidance.

content: Thanks a lot for the kindness!I will briefly describe what I have done for future me or anyone interested:Note: I have a 3303X-E with hardware version 3.0- Download and install Easypower from Siglent, modify easypower.exe per @optotester's instruction.- Download and install NI package manager.- Install NI-VISA, NI MAX, and "LabView and drivers" from NI package manager. (I think it is the "driver" included by "LabView and drivers" that matters.)- Connect to the PSU via LAN in NI MAX. Once done, the VISA test panel will be available.- Write the "FACTORY ON" SCPI command per @tv84's instruction. (May not be necessary)- Upgrade the PSU with this firmware (SPD3303X-1.01.01.02.05.ADS)- The PSU will reboot and become 3303X-edit:I didn't read the Release Notes first. It stated that: "B. < V6.1 hardware version of SPD3303X/X-E do not support upgrading to this version (SPD3303X_V1.01.01.03.10.ADS)". The result was the PSU will boot into the firmware update screen after reboot.
