  We present a technique for measuring the second-order coherence function
$g^{(2)}(\tau)$ of light using a Hanbury-Brown Twiss intensity interferometer
modified for homodyne detection. The experiment was performed entirely in the
continuous variable regime at the sideband frequency of a bright carrier field.
We used the setup to characterize $g^{(2)}(\tau)$ for thermal and coherent
states, and investigated its immunity to optical loss. We measured
$g^{(2)}(\tau)$ of a displaced squeezed state, and found a best anti-bunching
statistic of $g^{(2)}(0) = 0.11 \pm 0.18$.
