I'm using my 6022BE exclusively for checking audio amplifiers' output wave form. I'm mostly an analog guy so forgive me these 2 stupid questions:
1/ Is it possible to include in the software a power output measuring function. It's going to be very convenient if one could choose the load at which the amp is tested (maybe from a menu?) like 2, 4, 8 or 16 Ohms and then the software could calculate the power?
2/ Is it possible to include measuring the total THD of the amp in percent (sine wave). Not spectrum analyzer just total THD?

I would rather use a very design (USB) soundcard for that.

I'm quite happy with the 6022BE after finding PC SCOPE 2016 Software from Fabio1963 (see page 39). Stable Triggerpoint even when triggering a sweep (1MHz...5MHz square wave).
The main limitations of 6022BE are:
- Only a few pre-trigger samples available. ?: Needs change in the MCU firmware - anyone inside this topic yet?
- No AC Mode. What would be the best place to introduce a capacitor? Between first AD8065 (U12/9) and second (U11/7) together with a 74HC4051 to bypass it.
- 10V/div to 0.1V/div. There could be a bigger range if the second AD8065 is changed to an inverting amplifier with input signal moved to the - input of AD8065. No idea if this is a big hurt to the S/N ratio? Any analog specialist to discuss? I think of a 20mV/div mode (x50) and a 100V/div (x 0.1). The + input of the op-amp can be used to adjust/compensate an offset voltage and maybe safe the AC-mode.

Besides that I like the HW. The S/N is ok for me and I will not invest in shielding/capacitors yet.

Cheers,
Andreas

I just noticed that as of June, Sigrok added full 6022BE and 6022BL support: https://sigrok.org/blog/major-sigrok-releases-libsigrok-libsigrokdecode-fx2lafw-sigrok-cli-pulseview

That means Linux support as well...

Hello.
I did not have time to read the whole post, but I think this has not yet been commented on.
I just got my 6022BL, everything is working fine, but the hantek software is very limited.
I downloaded the Istrustar software (http://english.instrustar.com/download_detail.asp?nid=1570).
The software is great !!!!
But if I'm on the forum, I have problems:
How do I get Hantek to work on Istrustar software (they have practically the same oscilloscopes, just change the name)?
I tried to copy and paste the Hantek drivers in the Istrustar software folder, rename the files, uninstall the Hantek driver and try the Instrustar, but nothing worked.
Anyone have any ideas on what should I do?

Hernexto:
Isquicha, some places say they are similar only by outside.
Will be impossible to make it to work.

And pulseview (sigrok) doesn't want to detect my 6022BE... :(

I have so many drivers lying around... :-0
