  New front-end electronics including ASICs and FPGA boards are under
development for the ATLAS Monitored Drift Tube (MDT) detector to handle the
large data rates and harsh environment expected at high-luminosity LHC runs. A
mobile Data Acquisition (miniDAQ) system is designed to perform integration
tests of these front-end electronics. In addition, it will be used for surface
commissioning of 96 small-radius MDT (sMDT) chambers and for integration and
commissioning of new front-end electronics on the present ATLAS MDT chambers.
Details of the miniDAQ hardware and firmware are described in this article. The
miniDAQ system is also used to read out new front-end electronics on an sMDT
prototype chamber using cosmic muons and results obtained are shown.
