How to reduce the bandwith with very high sample frequency on USRP

Question

I am using USRP with DBSRX daughter board. I need a very high sample frequency. Currently, the USRP can give me maximum sample frequency of 64M/8 in I and Q, and the data type is short, which takes 2 bytes.

So can I decrease the length of the output data? for example save the data as char which takes 1 bytes, and increase the sample frequency to 64M/4. Can I do this? and how?

Answer 1

$ usrp_rx_cfile.py --help

See the -8 option which gets you 8-bit I & Q and allows a minimum decimation factor of 4.
