    Bandpass filter for WaveForms oscilloscope with Analog Discovery 2

    Hi, Here's the workspace I saved. with best regards, default.dwf3work
  2. Hi attila and D@n, Thank you for the detailed explanation. I understood that it takes time to make a high-resolution analysis on FFT. I want to know the meaning of the parameters of 'Channels options'. Are there any references?
  3. Thank you for the helpful reply. This option makes update frequency faster, but not enough for me. I think I should make a program to extract the low-frequency range by myself using the SDK. Thanks!

    Bandpass filter for WaveForms oscilloscope with Analog Discovery 2

    Thank you attila! This is exactly what I wanted to do. I couldn't set the lowest frequency lower than 1Hz, but it works for me currently. Just one more question: the filtered result dips deeply at the early phase as the attached image shows. I want to avoid this phenomenon. Is it possible?
  5. I'm using Analog Discovery 2 and Waveforms 3.7.5 on macOS 11.13. The spectrum analyzer works well. I want to view the narrow range of 1 to 100Hz. When I set the parameters Start to 0Hz and Stop to 100Hz, the update frequency becomes very slow. So I changed the BINs to 17, then it updates the data about for five times per a second. But the frequency resolution is poor. How can I increase the both of frequency resolution(about 0.1Hz) and temporal resolution(for example, 30 times per a second)?
  6. I'm using Analog Discovery 2 and WaveForms 3.7.5 on macOS 10.13. It works perfectly as expected, and I want to cut the fluctuation below than 0.1Hz and the power supply noise(50Hz). Is it possible to add a bandpass filter to pass between 0.1 and 50Hz to the oscilloscope?
