Hantek 6022BE 20MHz USB DSO

--- Quote from: Microcheap on February 07, 2019, 02:57:15 am ---Hantek's USB drivers are a mess. Try to do this: Open the Windows Device Manager and mark the option "Show hidden devices" in "View" menu. Remove all Hantek drivers. Unplug an plug the device again to confirm that there is no driver left in the system. When you see only the yellow exclamation mark, download the latest drivers from Hantek and manually install the Win 10 driver (even if you are using Windows 7), apparently this is the newest driver and what worked better for me. I am using Win 10 but I tested it in a Win7 VM.

I also tried the Win10-driver but there is no difference - only driver2 is installed. While testing the scop-softwares I did not reaize a difference between using Win7- oder Win10-driver.
I solved the problem with the non-working open6022 by using the really latest BL-HTMarch.dll from BL´s SDK-package (from Hantek´s homepage). The HTMarch.dll found in other directories of BL´s software-packacke is a little bit older. When using this youngest HTMarch.dll all third-party-software (BasicScope, PCScope, Open6022) is working.
Unsolved is the driver2-only-problem. I have forced to install driver1, but this installs driver1 only AND none software is working with (only) driver1. The Hantek-software does not akquire data and the other software do not work because it does not find the device/driver. I did not find a way installing driver1 AND driver2.

I also testet the available Saleae-software with my 6022BL, versions 1.1.15 and some newer versions up to 1.2.28. All 8-channel-versions Logic 8 worked, none else , esp. not the Logic16-versions, doesn´t matter what driver (kind and version) is installed. The Logic16-version are running but when aquiring data it reports that the data-rate is to high, but it says the same also with the lowest data-rate. Maybe it works with an older Logic16-Version, but the oldest version availabe on the Saleae-homepage ist 1.1.15.

Some days ago I got my 6022BE. The OpenHantek program works quite good but I found out that the displayed voltages are quite inaccurate. So I cloned the git repo and added the possibility to put calibration values into a simple text config file that is read at program start. Tested under debian stable & testing. I've also sent a pull request but unfortunately the original project is unmaintained at the moment.

Hi Charles,
I'm also about to modify the input stage of my 6022B. Your approach is ok as long as you don't want to measure small voltages, because you lose resolution. Wouldn't it be better to use a 1:10 probe to measure >5V?
My device only measures up to +4.8 V before the signal is limited. The problem with the 6022BE is that the ADC AD9288 operates far outside its spec. Correct is +- 512 mV between Ain and /Ain where the common mode voltage should be 0.7...1.1 V. With our device the common mode voltage is 0 V :( Have a look at Common-Mode Voltage: https://github.com/Ho-Ro/Hantek6022API/blob/master/hardware/AD9288_spec.png
Due to R8 inside the AD9288 the output of the U11 is also pulled up a liitle bit so that my real input range in is -5.2V..+4.8V.
My approach is similar to yours, but I only reduce R31/21 from 100k to 90k to be able to safely measure my 5V TTL levels without clipping and use a 1:10 divider for higher voltages (I am planning to build a 1:100 divider for 230V mains measurements).
As I use the device with linux only I'm able to change the program. I'm using OpenHantek https://github.com/Ho-Ro/openhantek that allows me to read in an individual calibration file with offset and gain for each channel and each gain step. Therefore I don't need to stick on factor 1/10.
I've collected some more HW documentation in my github repo https://github.com/Ho-Ro/Hantek6022API in directory "hardware".
Ciao, Martin
USA - Charles:
Note: I remove the post about the modification because the modification had not been tested and I have sold the unit. I decided that the 6022be didn't fit my needs.
Hi Horo, Ciao, Martin
I could add a jumper or a switch to select which side of the 90K ohm resistors would be used for the input for the ADC AD9288 then the factory mode or the modified mode could be selected. The problem is that I need to scope in 50v to 75v range and that is above the factory x10 probe voltage limit. I'll take a look at the links you provided.
I look on Ebay and the only low cost 100x probes are located in China and the sellers all have below the 99% positive feedback that I look for. I have purchase from China before and have about a 50% chance of getting the order.
Sinking more money into this scope may not be a good path to follow. I'm thinking about chipping out the money and replace it with something better.
Thanks for comments.
