This was sort of incomplete though, and got a couple of things wrong IIRC. I described the problem in more detail here: I checked back in on their website and NOW the product list has the and series scopes listed on the third page. Would you happen to know about this issue? Will try again later today and let you know.

I am pretty sure that many times, times is short… Thanks for your advice! This is the trigger index ahntek along with the uploaded waveform.

Anyone got a clue on what the problem might be? If it turns out, as I expect, that removing it makes the wave even more jumpy then I think it strong evidence that this transform is obfuscation, is required and we can stop thinking about it.

Both channels have this problem. How about the trigger? The information you shared helped me a lot. I am writing to you almost as a last resort! If you can take a 32kb sample and see that it looks right on gnuplot then that pretty much settles the matter. I am on the verge of giving up!

The triggering hantel rock solid. This especially with regard to autodependcies. Do you have the Digikey or equivalent part number for your mhz oscillator?

However, like Fabio, be assured that I am very appreciative for all your efforts! I have got a big problem. Also, just after the udb, a small signal MOSFET Q2 allows to engage a small capacitor from signal to ground, to add some sort of limited bandwidth mode.

There seems to be some room between the board and the edge of case so that air from the bottom can come up around OK. Waveform average, persistence, intensity, invert, addition, subtraction, multiplication, division, X-Y plot. Can you repair it?

I described the problem in more detail here: What would you guys suggest to try next? I have uploaded screen shots to https: The ADCs are humming along filling and refilling the 32K of ram one for each channel in this example.

Me, but somewhere else GitHub LinkedIn. The failure almost always shows do-2090 on the left side as and edge that arrives ahead of the actual trigger condition. Simple accessory that allow hanfek to take accurate secondary ignition measurements on COP ignition systems.


Software also lacks some “more than basic” functionality, that maybe will be addressed in future releases. Can I take dso-20900 20ns samples on two channels or am I limited to one channel for the a 32k acquisition? Or is the dso-20900 to pull that trick? I forgot that I set the averages to 2! Product Registration After-sales service Questions. Also, a multi-turn trimpot is used to manually calibrate the ADC full scale voltage. Was probably a bad solder joint then, with a bit of luck it should work fine for a while!

The multimeter probes offer a quick and easy solution, where a permanent connection is not required. The main requirement is that the sweep has to be fast enough that I only see one edge rising or falling. Disable GND setting since it is not yet implemented My todo-list says: The megabyte of memory depth makes capturing debug timing information a breeze.
