This board is factory installed on oscilloscopes as an optional interface and should require no futher connections to be made to it. The best 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. Me again, I forgot that I set the averages to 2! However, that may be the only case where a lot of bits change at once —. Good byer Good item Verified purchase:

New Hantek 40MHz PC Based USB Oscilloscope – DSO

One additional channel see R is fed into the analog comparator of the triggering circuit. I agree, by the way, that what the sigrok folks have written is a lot easier to read than the low level openhantek code. Can us repair it? Ok, but you should really open a thread on the openhantek forum here: What I see is an occasional stairstep down to 1 volt that occurs 20 us or so to the left of the trigger point.

The next step would be to move over to the sigrok code base and write up some simple tests. PPAs are Linux stuff.

Two days ago that was not the case. It then subtracts that starting address from the trigger address saved when the trigger occurred. Notify me of new posts via email. There may well be some simple feedback arrangement of logic gates on a sixteen bit shift register that produces this kind output. hantel


Inside a Hantek DSO-2090 USB Oscilloscope

I was able to solve some of the errors installing KDE packages and changing names of files but still no avail. My ChangeLog digest is: It has some nice features and performance for its price. The knows how large the buffer is so it subtracts from the current position modulo 32k of course by 10K to get to the start of the captured waveform.

I anticipate reconnecting in the near future. Finally it work but I noted that the calibration tip reads as 2. The information you have provided here is extremely useful to me. In other words, vertical measure is fine, horizontal is not. Channel two seems to work fine on the whole range.

The analog multiplexer is controlled by the CPLD, and there seems to be a couple of clamping diodes D1, the other is bottom mounted into both signal paths from the frontend to the multiplexer. Show less Show more.

Someone out in the cloud mentioned that it had a real limitation in that the deep buffer only worked at a very slow sample rate. To avoid injury keep the probe away from moving parts, such as the alternator drive belt and cooling fans. Ahntek would be very surprised that a 60 mhz part would work at over twice its rated speed. XFCEseems that the previous repository is not working anymore.


I think that removing the call ush the transform in OpenHantek will make the trigger much more erratic — especially when moving the trigger point around. I grabbed the latest git trees and rebuilt everything and now it just works, well done! Still udev or what else should recognize the DSO not working.

It’s an necessary interconnection cable for general function and signal generator applications. I forgot that I set the averages to 2!

However, that may be the only case where a lot of bits change at once —. Save waveform in the following: Show More Show Less. Jantek Welded Assembled Dso 2.

Nothing to be done about it in that case and it makes the above speculations academic. Lead length 30 meter.
