The upcoming parity violating deep inelastic scattering (PVDIS) experiment E08-011 in Hall A at Thomas Jefferson National Accelerator Facility (Jefferson Lab) aims to measure a combination of the axial hadronic couplings of the electron with a factor of six improvement in precision over world data. Precise data for the couplings are essential to search for physics beyond the Standard Model. The experiment will measure a 10?4 asymmetry using polarized electron scattering from deuterium with a beam energy of 6 GeV. Recent progress on the preparation for this experiment, with an emphasis on the tests of the data acquisition system and the capability of measuring a small asymmetry, deadtime, and pileup effects are presented.
