This paper presents a new digital beam position monitor
(DBPM) system which is currently under development
for the Swiss Light Source (SLS). It is designed to
provide sub-micron position data in normal closed orbit,
and feedback mode as well as turn by turn information
for machine studies and real time tune measurements.
The self calibrating four channel system consists of a RF
front end, a digital receiver and a DSP module. The same
electronics will be used in all sections of the SLS accelerator
complex. The system can be reconfigured in real
time to perform different kind of measurements like:
pulsed for linac and transfer lines, first turn, turn-by-turn,
closed orbit, feedback and even tune mode for booster
and storage ring. These reconfigurations only involve
downloading of new signal processing software and will
be performed via EPICS control system. An independent
system for monitoring mechanical drifts of the BPM stations
will be installed as well. The measured data will be
permanently updated in a database and taken into account,
when processing the final electron beam positions.
