The experiments are carried out using the circulating beam as well as the beams extracted from the ring and delivered by three beamlines. The original BPM system still operational in the ring does not fulfill the requirements for new experiments. It utilizes cylindrical and shoe-box type diagonally cut capacitive pick-ups. The most signal processing is done the analog way. Additionally to its age and the increasing failure rate, the analog processing introduces large drifts in e.g. the offset, which regularly require a significant effort for manual calibration. Even then the drifts render it impossible to match the requirements of the planned JEDI experiment, which is an orbit with a maximum of 100 um RMS deviation. Therefore an upgrade of the readout electronics was decided. The decision process is described, the implications listed and the current status is reported.
