Slowing down PXI 5422 ?

Here is a question on the PXI5422 waveform generator running on Windows with LabView.  Is there any way to get it to output at a longer time step than 5 ns ?  For instance, we have an array 2E6 samples long we want to output, but by default it is 5 ns x 2E6 = 10 ms long, and we would like to stretch it to 100 ms for instance (it seems we can't add many more points to the array because we only have 8 Mb memory).  In other words, is there any way to output a 10 Hz signal for instance ?  My original assumption was that since most 1 GS/s digitizers can work more slowly, say at 1 MS/s, by analogy a 200 MS/s waveform generator could work more slowly, say at 1 MS/s.

You can change the Sample Rate property to a value lower than the default 200e6.

What VI do you use to do that ?

 

Thanks,

niFGen Set Sample Rate.vi seems to do it.
