I suppose you are not talking of the DC function. Is it the values with the Sine function?

This is strange that your selftest is not working but your HDG seems OK... Did you already try to see if some specific function is not working?

In fact I just realized that the ranges are not the same depending on the function your are working with   :palm:
I just captured data to the shift register with the DC function from 0 to 10V and and I only saw 2 ranges. I didn't pay attention up to now but I can hear also 3 clicks on the sine function range: around 100mv, 1.3V and 1.4V. It's very strange it is so close for the 2nd and the 3rd on my HDG.
I will open my HDG again and will try capture with other functions. Maybe I will figure out what X4 & X5 are used for...

That's at least the good news with your HDG. You seems to be the first person here to have this new version :)
I wonder what Hantek solved with this last release.
The .1 in the PCB version is surprising... let's hope that PCB 1004 and 1004.1 are compatible so that other people will be able to use the new FPGA 30.
From what I saw, FPGA versions are linked to PCB versions (which seems quite logical). As I have a PCB 1002 for example, I have to stick with FPGA 11 even if I could upgrade to Software 1.00.2.
Would you be able to backup your HDG and PM me a link to it? Don't post it directly here unless you want to share your serial  :D
I suppose that now they won't change the partitions on the nandflash anymore so that you can use the 1.00.2 backup scripts posted here: https://www.eevblog.com/forum/testgear/hantek-hdg2002b-awg-5mhz-or-100mhz-let's-see!/msg540248/#msg540248

To make it easier, I also created today 2 scripts that use the update process of the HDG to backup the nand flash partitions directly to a sd or a usb stick. You can now backup the HDG without opening it (plus the calibration file and the system.inf file are also saved just in case). The backup will be in the "backup_hdg" folder, either on your SD or USB stick, depending on the script you choose (The backups are not compressed like they were in the older script in order to speed up the backup process).
To use the new backup scripts, just unzip the one you want to use and put it on your backup media, go in the Utility menu, select Update, select your disk, select the backup script... and launch the update. It will last for 3 to 5 minutes, depending on your media speed. Don't be afraid by the "Updating..." message. It does not write anything on the HDG. After the backup is finished, the HDG will reboot automatically.

Are some of you interested in real upgrade scripts? I upgraded from 1.00.1 to 1.00.2 by flashing the nand with an external tool because of the nand layout change but I think this could also be done via the upgrade process. Upgrades from newer versions will be much easier to do.

I ran your script and PM you the ftp information to grab it

Thanks to Sandra's backup I was able to upgrade my HDG from 1.00.2 to 1.00.3 (I still have an old PCB 1002)

This version (1.00.3) seems to be a big improvement in term of stability. I played with it for 1 hour and I had no freeze nor reboot.
The calibration file from the previous version is not compatible. I had to run the calibration process again (I just run the DC part as it takes a lot of time).

The way the 3 ranges are used also changed and now, like Sandra, I can hear the relays clicking around 100mV, 2V and 5V for a Sine function at 1kHz (it also changes, depending on the frequency).
The .1 from PCB 1004.1 seems to be related to a modification on the output relays of channel 1: just after upgrading the software to 1.00.3, I replaced the FPGA config file (FPGA v30 now) with the v11 corresponding to my PCB 1002 but kept the PCB version unchanged in the system.inf file (1004.1). I had only channel 2 which was working. No click for channel 1. With "PCB 1002" in system.inf, channel 1 was back on duty!
With "PCB 1004" in system.inf , my 2 channels are still working and I have an extra menu in Utility which is "Word Generator". This "Word Generator" Menu is not displayed when I put "PCB 1002" in system.inf. As there seems to be an extra chip on the PCB1004, I suppose it is related to it..

Regarding the Self Test, apart from the 4 first steps which are succesfull, the 6 last steps are failing... but I did not see anything wrong during the time I played with the HDG.
I will perform a full calibration on both channels and will try again later on.

Edit: No failures anymore during the selftest after a calibration of both channels  :)

Did you have all tests pass again in the self test?
I am curious if this version just behaves differently or if I have a bad unit.

Got my first reply from the seller on this.   
They suggested to not power cycle the unit so fast and wait at least 30 seconds before turning back on.
Replied.  It had been off for at least 8 hrs then was on for at least 5 minutes before running the self test. 

FWIW, no where in my message to them did I mention the unit was ever power cycled.  OYE, its going to be one of these

smgvbest:
@fremen67
So with the 1.03 software you are seeing failures now in the self test also?
if so that could be they broke the self test and did not fully regression test the unit out.  from what I've been reading that would not surprise me of Hantek.   

I've not run into any real issues with it other than lack of a decent manual in english
