DSO-2090 LINUX DRIVER DOWNLOAD

This is the signal I see: Seems like you are pushing the limits with mhz. I have verry good soldering skills, but have no real idea about the inner workings of the scope, so thanks for the useful info. When I found 1. Leave a Reply Cancel reply Enter your comment here

I will definitely try it out with the 75Mhz. I have a single udev rules file where I add all my custom rules to make things easy to backup. Have not heard back from Oliver yet, and the openhantek. I am on the verge of giving up! I went with the openhantek version because it was obviously cleaner.

We take these very seriously! The inverse of the this XOR shift operation is very simple — just start on the left side and shift right. The memory depth is crippled at settings under 40 us per division. I suspect this is what you are seeing too.

Also, just after thea small signal MOSFET Q2 allows to engage a small capacitor from signal to ground, to add some sort of limited bandwidth mode. Fabio, please file a bug report sdo-2090 that segfault you saw. From there, when you connect it to USB, the firmware will automatically be uploaded.

Getting the Hantek DSO working with Linux –

Thanks for all the good conversation and useful information! I believe the transform is dwo-2090 and that it is done as an easy to implement XOR obfuscation technique.

Those figures probably only matters if your are building something more high end think of having the ADC part of a more complex signal processing chain ….

DSO is short circuit.

WordPress garbled the last comment toward the end. I never see a glitch if I am showing three edges on the screen. Should I need to calibrate somewhere?

Openhantek

Could not find one so far: As Hantek also sells similar models with higher performances, I immediately took the device apart to better understand how it works and to see if it can be pushed a bit more, especially regarding the realtime sample rate. This is the trigger index sent along with the uploaded waveform. May be enough to ask the seller to send a new unit….

These guys love to copy each others. Is it dso-20900 known if some new incompatible? I grabbed the freshest source from the github repo and it compiled without a hitch. Was probably a bad solder joint then, with a bit of luck it should work fine for a while!

Inside a Hantek DSO-2090 USB Oscilloscope

Seems like that would cause the same propagation delays as using logic gates on outputs of a conventional counter as described above. When I run the software it freezes the computer. I described the problem in more detail here: I am kind of ashamed posting this question reading the level of the topics already posted. This from the previous diff of dso.

I think the inputs have relays on them and it seems this is normal. Curiously enough, the resistor is actually shorted with a 0 Ohm, so the designer decided to use the actual internal circuitry of the as part of pinux filtering. To visualize actual data, I helped things along with the command line to massage the output a bit and save it to a file by doing. Having said that, there is no reason that I can think of why Hantek would want to do this — after all, they sell hardware and give away software.
