how to set parameters and debug in AD9361 with GNU Radio

 Recently i am working  with AD9361+ZC706 setup based on GNU Radio to realize  base-band digital modulation system(FBMC). FBMC system doesn't have mature standards settings like LTE. Then i am confused about how to set parameters in FMCOMMS-2/3/4 blocks in GRC, especially RF bandwidth and sampling rate setting.i have read the manual GNU Radio [Analog Devices Wiki] and AD9361 high performance, highly integrated RF Agile Transceiver™ Linux device driver [Analog Devices Wiki],but they don't illustrate how to calculate the settings based on our own systems.

   Since the base-band part transmit-receiver data and waveform is correct, i don't know how to debug radio frequency part (AD9361) in GNU Radio  when receiver waveform is unexpectedly. can anybody help me? Thanks !!
