I use C++ to control the LimeSDR-mini.
So, one of my test is set high TX and RX Gain.
rx_buffer[2 * j] and rx_buffer[2 * j + 1] is the I/Q value.
But when I calculate the Magnitudes, it’s construct a square.
And I find, I or Q seems has a threshold equal 1.
What happened to the LimeSDR-mini or just my wrong setting?
But when I decrease it, it’s seems good.
What’s more, when the gain, increase, the I/Q value construct a circle, it’s become very unstable. it’s seems like the DC offset. is their any way to deal with this problems. because now, I am trying to use LimeSDR-mini as a VNA, send the signal through the antenna to sensor and use TDD mode to receive the signal. is their any fast way to scan controlled by C++?
