Many next generation adaptive optics (AO) systems, on both 10-m class telescopes and future giant segmented telescopes, plan to incorporate a pyramid wavefront sensor (PWFS) to achieve their performance requirements. As a significant number of the instruments being developed at National Research Council Canada Herzberg Astronomy and Astrophysics Research Centre (NRC-HAA) contain a PWFS, we have re-established a PWFS testbed. We present the design for the AO PWFS bench and first light results. A key design of the bench is the portability of the PWFS arm such that it can be installed on NRC-HAA's local AO system for on-sky testing of the PWFS with the Herzberg Extensible Adaptive optics Real-time Toolkit as the real-time controller.
