HANTEK DSO-2090 USB DRIVER DOWNLOAD

But still I wonder why! The whole design is quite easy to understand, and the most interesting thing to hack is the actual CPLD clocking to allow for a higher single shot sample rate. Especially when it got warm, it gave me the red blinking led. Yeah, I did the comparison as well at the time. Lots of undocumented changes. This is controlled by the Cypress USB interface and has two channels wired into a buffer the signals are trough R and R and summed in analog to the two input signals to control the offset.

Inside a Hantek DSO-2090 USB Oscilloscope

I guess I just landed on a buggy commit last time. Could you estimate how often do you see the wrong waveform when sampling the 1kHz test signal?

If so then maybe some holes would be helpful. When I move the trigger slightly to the left the jitter is much diminished. Test lead of a male BNC connector to 2 4mm connectors. Connect the breakout lead plugs into the existing wire loom, and insert the two 4mm banana plugs into the scope using test lead HT30A, hsb output signal can be taken. Is it also known if some new incompatible?

Lead length 30 meter. But if the algorithm is so wrong I would expect to see the triggered edge jump around as I manually move the triggerpoint along sample. Your waveform is showing several edges. You mention that there are two slots for oscillators.

May be enough to ask the seller to send a new unit…. Designed to aid diagnostics on secondary ignition circuits by allowing an HT measurement to be made when there are isb, or limited access, to any spark plug leads. Post something if you get some result! I make it work on Windows 8 last nigth.

Yeah, I did the comparison as well at the time. The ussb part for me is that with the OpenHantek software, it works just fine in a Linux system, and has a nice full open source software for the control application.

Let us hantei if you manage to give openhantek a try! Implement bandwidth limiting filter on both channels and HF rejection filter on trigger Implement calibration for fastrate, including DSO It seems to be a problem that tends to make the buffer pointer higher than it should be and often by fixed and not too great amounts.

Try setting the scope to 10 us and leave the trigger point at 50 percent like you have it in the picture. I would like to fix it or is it just a waste of time. Trigger normal on — edge and trigger at 1. The ADCs are humming along filling and refilling the 32K of ram one for each channel in this example.

I described the problem in more detail bantek Hi Fabio, I only see the bad triggering when the waveform is expanded so only the trigger edge shows on the screen. I do have a DS handy to do some further investigation.

I came upon this disturbing note in dso. Integral injection molding makes the usage more flexible and the oscilloscope able to adapt more testing situations. The bad part is that there are not many dso-20090 features. The failure almost always shows up on the left side as and edge that arrives ahead of the actual trigger condition.

Nothing to be done about it in that case and it makes the above speculations academic.

It was averaging two waveforms and only one had the glitch so the average of the two would be dso2-090. Hi Francisco, which repo are you using?

My this year birthday present was a DSO I am on the verge of giving up!
