I had noticed that the first ten samples of my application were always coming up as zero regardless of whether it was 8-bits on host or 16-bits on host. I went down the path of trying to reproduce a minimal example to share with this mailing list, however I then realized that even the example "rx_timed_samples.cpp" was also producing the same results. This occurred with two different b200minis and a B210 with UHD 4.7.0.0. I had to de-boostify the source code to run on my system and specify a center frequency and receive gain, but am able to reproduce this issue every time. I've confirmed that a signal is present by using a signal generator for one setup and also with an OTA setup tuned to 2421 MHz with AGC disabled and receive gain set to 70 dB.
Has anyone observed this issue or can anyone else reproduce it using the timed receive example as well? Sorry if I am missing critical details that would help diagnose the issue, let me know if any additional information would be helpful. - Chris
