We develop a time-ordered data simulator and map-maker for the proposed PIXIE
Fourier transform spectrometer and use them to investigate the impact of
polarization leakage, imperfect collimation, elliptical beams, sub-pixel
effects, correlated noise and spectrometer mirror jitter on the PIXIE data
analysis. We find that PIXIE is robust to all of these effects, with the
exception of mirror jitter which could become the dominant source of noise in
the experiment if the jitter is not kept significantly below $0.1mu
msqrt{s}$. Source code is available at https://github.com/amaurea/pixie.
