Re: 2204A effective AWG resolution

Surprised to see that this issue has not been fixed after almost one year. Surprised because my experience with Picoscopes otherwise is well functioning hardware that is up to spec, excellent software and a very useful SDK for implementing custom applications. The official

    Re: 2204A effective AWG resolution

    Gerry, Thank you for looking into this. The PicoScope is convenient for my application because I can generate a sensor excitation and record the response using a single unit. However the limited resolution is a bit of a showstopper at this point because it introduces noise that I cannot easily filte...

    Re: 2204A effective AWG resolution

    After some more testing I found that the PicoScope software approximates waveforms in 255 discrete steps corresponding to 8 bit resolution. I checked this by selecting an exponential waveform in the editor and then saving as a CSV. After pressing 'Apply' and going back to the editor the waveform is ...

    Re: Rise Time specification for 2206B AWG

    You can also look up the PicoScope 2000 series spcifications here and find that the rise time (10% to 90%) for the 2206B AWG is specified to be less than 120 ns.

    You can easily add a rise time measurement in the PicoScope software to verify that the scope is within spec.

    2204A effective AWG resolution

    Hello, I am using the PicoScope 2204A AWG to generate pulses with exponentially rising and falling edges and I am curious about relatively large steps in the output near the max value of the waveform. See the attached for an example of data captured by connecting channel A directly to the AWG with w...
