Can we change the baseband sampling freqency of the board

As per the WARPLab reference design example we have
% Get the baseband sampling frequencies from the board
ts_tx   = 1 / (wl_basebandCmd(nodes(1), 'tx_buff_clk_freq'))
ts_rx   = 1 / (wl_basebandCmd(nodes(1), 'rx_buff_clk_freq'))
we are having two WARP boards (nodes), both the boards provide same tx and rx sampling frequencies. can we vary the sampling frequency of the two boards also can we vary he tx and rx sampling freq for the same warp board?  If yes, how?

Re: Can we change the baseband sampling freqency of the board

The WARPLab Reference Design implements a fixed 40MSps sampling rate. You should implement whatever rate changes you need in your M code. For a narrowband waveform, you can implement an interpolation filter in your Tx code and decimation filter in your Rx code.
