Sean, if I remember correctly, the filter configuration (whether or not a filter is bypassed) is determined by the ratio of DAC rate to master-clock rate (the interpolation that needs to happen inside the ad9361) thus, you can only somewhat, indirectly, control it by changing the master-clock rate.
However, if you can live with the interpolation inside the FIR, you can reprogram the fir taps to whatever suits your needs. For examples take a look at: https://github.com/jarn0ld/uhd-filter-tool Hope that helps. Cheers, Julian Julian Arnold, M.Sc > On 10.
