[Discuss-gnuradio] Why is set_rx_format not implemented for USRP2?

[Ulrika Uppman]

Hi everyone, 
I would like to set the data width to 8 bit I and Q (instead of 16 bit) on the 
wire when receiving data from the USRP2 to be able to receive a wider frequency 
range. I found the set_rx_format() and set_tx_format() functions in usrp2.h but 
they aren't implemented. My question is if there are any particular reasons why 
this functionality isn't implemented?

I am also assuming that it is possible to set the decimation rate to a value 
less than 4 (when the gigabit ethernet isn't the bottleneck and also assuming 
the host computer can handle it), is this correct?
