I use the signal source to produce 101010 ... sequence, modulation for the BPSK, carrier frequency of 2210MHz, AD9361 received by the local oscillator frequency of 2210MHz.
The following are the shapes that are received when the symbol rate is 5k sym / s and 500k sym / s:

It doesn't look like the BPSK waveform, why? Is the carrier not synchronized? If the carrier is not synchronized, how to synchronize? Or is not enough bandwidth? Or AGC did not adjust well?
