In this report we describe the construction and characterization of a small quantum processor based on trapped ions. This processor could ultimately be used to perform analogue quantum simulations with an engineered computationally-cold bath for increasing the system's robustness to noise. We outline the requirements to build such a simulator, including individual addressing, distinguishable detection, and low crosstalk between operations, and our methods to implement and characterize these requirements. Specifically for measuring crosstalk, we introduce a new method, simultaneous gate set tomography to characterize crosstalk errors.
