Neutrinos are fundamental particles. They are amongst the most difficult particle to detect due to their properties. Their existence have been known for a while, yet their masses still have not been measured. The Enriched Xenon Observatory is attempting to probe their masses by observing the neutrinoless double beta decay in 136Xenon. Their detector is a liquid xenon filled time-projection-chamber. To ameliorate their measured sensitivity, an improved, scintillation and ionization, detector is required. The work presented here focuses on the development of a new charge readout scheme. A small gas TPC was built to test different charge readout pads. This detector measures the ionization signals produced in isobutane gas. Signals are read by a commercial data acquisition system. The data analysis will demonstrate the challenges faced during the operation and modelling. The energy resolution and angular distribution results provides guidance for the collaboration for the future of these charge readout scheme.
