[Discuss-gnuradio] Sampling rate and USB interface

[Lin Ji]

Hi,

  In the USRP documents it says that the ADC has a highest sampling rate at 64Msps. From some response from the mailing group I got to know that the sample rate is at 32Msps. Which one is the 'REAL' samplng rate?

  If I have a signal that has a chips rate 11Mbps, assume that the sampling rate is 64Msps,that mean for every bit there will be 64 samples. It sounds impossible that the USB interface can transfer that amount of data to the PC, and the buffer on the board can not be enough. How shall I encounter this problem?

  BTW: I would really like to read some documents on how to reprogram the FPGA using Altera Quartus II, if there is any, thanks.
