I have AD9371 IC with Zynq ultrascale plus MPSoC on the custom board.
While checking BIST tone, I am getting spectrum like this
LO frequency is at 2345 MHz (check marker 2)
The main frequency is 2348 MHz. (marker no. 1) and its image is shown by marker by 3.
I have observed LO frequency at 100KHz span. So it seems like it is not locking at one frequency.
Please give suggestions.
