I am struggling with how to use IIO as a spectrum analyzer for the DAQ2 board. There are multiple issues:
1) I am comparing the results on a traditional spectrum analyzer and I am not getting anything close to what IIO is giving me. I don't see the DAQ2 output signal at 1 GHz +/- 30 MHz at all. My main purpose is the use it to capture the DAC output from your DAQ2 development board running on a Xilinx KCU105. I am expecting to see a signal using Frequency Domain at either 500 MHz or 1GHz for the JESD output.
2) The zoom around a window goes back to full zoom after a few seconds.
3) I am seeing many spurs even when the development board is turned off. The picture below is with the output powered off.
I am using v0.7-master on Windows 10. Should I be using another branch? My platform is the Avnet PicoZed SDR SOM 2x2 Development board.
