We use the CASA software package to synthetically observe binaries forming as a result of turbulent fragmentation in a radiation-hydrodynamic simulation of a collapsing molecular cloud. By following the evolution of such pairs beginning in the prestellar core stage, we are able to make predictions about the feasibility of observing such fragmentation using the Combined Array for Research in Millimeter-wave Astronomy (CARMA) and the Atacama Large Millimeter/submillimeter Array (ALMA). We find that while intermediate ALMA configurations may potentially resolve structure with one fourth the integration time of CARMA, both instruments only marginally resolve sub-structure within 25 kyr of the onset of gravitational collapse. In addition, interferometric spatial filtering significantly reduces traces of filamentary gas morphology on < 0.1 pc scales. Thus, even with the improved sub-arcsecond resolution of ALMA, constraining stellar multiplicity at the earliest stages of star formation will be challenging.
