The superconducting electron accelerator MESA is currently being built in Mainz. At this facility, the P2 collaboration aims for a high-precision measurement of the weak mixing angle at low momentum transfer, serving as a test of the Standard Model with a sensitivity for new physics up to a mass scale of 50 TeV. In the experiment, spin-polarized electrons with changing helicity are scattered on a hydrogen target. The parity-violating asymmetry due to the weak interaction of the scattered electrons is measured using a Cherenkov detector ring.

The readout electronics is developed in collaboration with the University of Manitoba and needs to be understood and characterized. In this poster, the P2 experiment is introduced, test setups will be described, and the first results will be presented.
