  The RD51 collaboration maintains a common infrastructure at CERN for its R &
D activities, including two beam telescopes for test beam campaigns. Recently,
one of the beam telescopes has been equipped and commissioned with new
multi-channel and charge-sensitive front-end electronics based on the ATLAS/BNL
VMM3a front-end ASIC and the RD51 Scalable Readout System (SRS). This allows to
read out the detectors at high rates (up to the MHz regime) with electronics
time resolutions of the order of 1 ns and the ability to handle different
detector types and sizes, due to a larger dynamic range compared to the
previous front-end electronics based on the APV25 ASIC. Having studied and
improved the beam telescope's performance over the course of three test beam
campaigns, the results are presented in this paper.
