  In this proceeding, we present studies of instrumental systematic effects for
the Simons Obsevatory (SO) that are associated with the detector system and its
interaction with the full SO experimental systems. SO will measure the Cosmic
Microwave Background (CMB) temperature and polarization anisotropies over a
wide range of angular scales in six bands with bandcenters spanning from 27 GHz
to 270 GHz. We explore effects including intensity-to-polarization leakage due
to coupling optics, bolometer nonlinearity, uncalibrated gain variations of
bolometers, and readout crosstalk. We model the level of signal contamination,
discuss proposed mitigation schemes, and present instrument requirements to
inform the design of SO and future CMB projects.
