Diottix r was calibrated at 25 Hz to achieve the frequency indicated in literature as being effective to mobilize the airways secretions. I think the inputs have relays on them and it seems this is normal. However, putting the OpenHantek dso-2090 in Auto mode and changing the timebase down to 10ms or less and I started seeing some action.

I would never again buy a scope without the ability to move traces vertically, as in matching up waveforms. One dso-2090 found this helpful. Finally I got the windows 10 drivers and work quite well.
Your observation about the hantekdso guy translating dso-2090 code language is interesting. But maybe he was duplicating what is possibly a bogus method to begin with. Who knows? There are two issues here. The second is the erratic triggering. I believe the transform is required and that it is done as an easy to implement XOR obfuscation technique.
Having said that, there is no reason that I can think of why Hantek would want dso-2090 do this — after all, they sell hardware and give away software. If anything they should publish the low level interface to the board and make it easy to work with. Their product protection is the code in the CPLD. The inverse of the this XOR shift operation is very simple — just start on the left side and shift right. So I think the code encrypts the trigger position and the Hantek display software decrypts it. XOR is the most popular instructions for obfuscation and this particular method is very easy to implement and requires no key.
That Oliver Haag saw what it was is pretty amazing.
DSO-2090 40 MHz USB Digital Storage Oscilloscope
It runs continously when the scope is enabled. The display software sets the hardware up with a trigger level, a buffer size and a trigger position. This information gets sent to the that is running the downloaded driver. It uses that info to set up the CPLD and is responsible for reading the waveforms and trigger data back to the PC after an dso-2090.

The Dso-2090 is a downcounter set to the trigger percent of the current buffer size. The ADCs are humming along filling and refilling the 32K of ram one for each channel in this example.
A trigger event occurs and two dso-2090 happen. First — the current position in the buffer is saved in the CPLD because that will be needed to calculate the trigger position in the upload buffer later on. Designed to aid diagnostics on secondary ignition circuits by allowing an HT measurement to be made when there are no, or limited access, to any spark plug leads.Turn your Windows based computer into a powerful 40 Mhz 2 channel digital oscilloscope. Using the PC's USB port for data communications between the included hardware dso-2090 software to create the oscilloscope display on the PC's monitor allowing you to preform functions the same as on.
