How do you change sampling_frequency with FMCDAQ2/ZC706?

I am working with the FMCDAQ2 board and the ZC706. I am trying to run some of the demo modulations, like chirp.mat. It runs fine, but the sampling_frequency for the FMCDAQ2 (AD9144) is set to 1 GSPS. I know it can go up to 2.8 GSPS and has an on-board clock generator, I am pretty sure. How do I change the clock frequency from 1 GSPS to, say, 2.4 GSPS? Where is the source code that sets sampling_frequency? On the IIO Oscilloscope program, it looks like that is the name of a file, but I can't find it anywhere.
