It depends.

If those frequencies are separated by less than the analog bandwidth of 
a single daughtercard, then you can use the dual-DDC feature to
  pick both of those frequencies out of the larger bandwidth. 
 Otherwise, you must use another card.  Each daughtercard has only a single
  analog downconverter, and there's only a single dual-channel ADC to 
sample the output of the card.
