Sample frequency of USRP

hi all:

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?

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

I am currently writing program by myself. Because I can not understand
the python code. If I want to do this, which file I need to change?
Which file in the gnuradio set the output data length?
