We report multiheterodyne-detected cavity-enhanced absorption spectroscopy (MH-CEAS) of CO$_{2}$ in the near-infrared using a novel frequency comb light source generated from the electro-optical modulation of a single continuous-wave laser. Using a pair of dual-drive Mach Zehnder modulators we create two frequency combs of slightly different comb mode spacing. The probe comb is coupled to a high-finesse optical cavity containing CO$_{2}$ and then combined with the local oscillator comb on a photodetector. This results in down-conversion of the optical comb to radio frequencies, therefore facilitating fast, multiplexed analysis of the CO$_{2}$ direct absorption signal. The noise-equivalent absorption coefficient for MH-CEAS as initially demo...
