Hi, I want to use the B200 as capture device. I connect the 10Mhz clock from my signal generator to the 10Mhz port on the B200. Do I need to pass in any command to the "rx_samples_to_file" example to use the external clock, or the driver automatically detect and use the external clock? Thanks James

Hi James, You should specify "--ref external" on the command line, if I'm not mistaken.

Hi Marcus, Thanks for the tip. The "-help" of rx_samples_to_file is a little misleading for saying --ref arg (=internal) waveform type (internal, external, mimo) But now I know.

 Hi,

   

 I want to use the B200 as capture device. I connect the 10Mhz clock from my signal generator to the 10Mhz port on the B200. Do I need to pass in any command to the "rx_samples_to_file" example to use the external clock, or the driver automatically detect and use the external clock?

   

 Thanks

   

 James
