  1. Hi, i have been analyzing signal response from a DUT (a resonator) using network function in waveforms. For comparison, i ran the same setup and parameters on the actuation signal using a lock-in amplifier (MFLI) separately. Both responses are attached below. So far i have been getting very similiar response (from frequency and phase shift perspective), but with a significantly different amplitude. https://imgur.com/a/xlJ2DWM (for some reason i kept failing to upload directly here ) The parameters of the reference signal were: Ampltude: 3V DC-Offset: 2V Frequency: 203.31 kHz I am quite new to signal processing (especially working with an ADC), so i might miss some details that should have been taken into account. Could someone help me explain, what could possibly influence the amplitude different shown on each response? I appreciate your time and response greatly! Regards, Jody
  2. thank you for the answer @attila i've been using the RPi 4 now and waveforms is working well.
  3. Hey just found your guide as i was having the exact same problem on RPi 4. Thank you so much! If i wanted to run a Project using AD2 on Boot, do i need to enable digilent runtime on boot as well?
  4. Hi, i have been trying to run waveforms on my Raspberry Pi 3 B but keep getting errors either by getting power from USB Port on Raspi (Overcurrent, although i checked the current limit to to 1A) or by using a power supply (5V, 2,5A), which is giving me under voltage error. I read somewhere in the digilent forum that these power problems do occur in the older versions of Raspberry Pi (up to 3 B+) because of the USB 2.0, and have been sorted out as the Raspberry Pi 4 was released. Had someone actually been able to run the AD2 on Raspberry Pi 3 B without problems? Any response is very much appreciated! Thanks!
