Here is the modified version of the HDG calibration tool with:
- Excel x64 support (thank you smgvbest for the feedback)
- 34401A DMM support for DC values
- Rigol DS/MSO2000A support thanks to flatlander
- Excel sheet update improvement

If you don't want to use a device (DMM or DSO), just leave the adresss/alias empty.
The DSO detection type is done using the IDN string so it should be able to detect a DS/MSO1000Z and DS/MSO2000A (hopefully :P).
Depending on the calibration value type, you should be prompted to connect the correct device to the HDG.

I also wanted to add a progress status bar but it's bed time here ...
Hope this will help!

Do you know how this can work with the Hantek DSO? The HDG is loading with the IVI driver but the DSO5072p (upgrade to 5202p) is not recognized with the Hantek driver, I am looking for a compatible one but not had any luck yet.

I was able to use you spreadsheet tool to record and upload the config using the latest version you provided (thanks!) but wanted to automate. Any ideas on how we can do this?

The HDG2002B I have has;

HW: 1004.1
SW: 1.00.3.02.03(1504230)
Kernel: 3.2.35
FPGA: 30
Kybd: 3

Thanks in advance.

Hello Starcruiser,
The Excel calibration tool is only able to connect to instruments that support SCPI commands (via VISA driver).
As far as I know,  the DSO5072p does not support scpi commands.
I have a DSO5062D and I can't use it for the calibration of my HDG2002B. It would require to write a driver on the PC side which would be able communicate with the specific protocol of Hantek DSOs.
You will find informations on that protocol here: http://elinux.org/Das_Oszi_Protocol
It seems that someone got a calibration tool from Hantek that works with Hantek DSO ... https://www.eevblog.com/forum/testgear/hantek-hdg2002b-awg-5mhz-or-100mhz-let's-see!/msg577081/#msg577081 but I don't know how to get it :-//

The SW version of your HDG is a new one. Would you be able to dump your HDG and post somewhere the files so that I could create a update file? You will find an "upgrade" package in my onedrive that will allow you to backup your nand  https://onedrive.live.com/redir?resid=C666E0DC0AF0C9E2!114&authkey=!AMtRrjm2d33uI8Q&ithint=folder%2c (in the backup folder).

Thanks in advance! :)

@Starcruiser and @Fremen67
I'd love to see that dump also,  maybe they fixed that zoom selftest finally  :-//

Im having some really bad effects after the upgrade, namely at any frequency beyond 5Mhz, the amplitude goes nuts.
Ch1: looks right below 1V,above that it jumps to 22V
Ch2: about 6x the value set, above 1V (till 20V) fixed 22V
Adding offset also causes total f..up.

With sweep, the amplitude stays stable IF the frequency is set to max. 5Mhz before turning on sweep.

Any idea what causes that, and how to fix it? Some sort of countermeasure?
At the moment, i can just downgrade it again to avoid breaking everything :(

Just remember that i tried to do the DC calibration, and it decided to reboot after a few values. Maybe related... Didnt check the amplitude flatness before that, so i dont know if it ever worked.

Ok, looks like the failed calibration is to blame.
Did a quick and dirty cal of Ch2 again, and now it looks much better. I dont know why it crashed on the first attempt.
Amplitude is surprisingly stable even up to 100Mhz, maybe -2db. Flatness is so-so but probably caused by my QaD Cal. I could do much better with some more time and motivation (and using my LeCroy 9354 in my main lab instead of the old 9304 here).
