The new Data Measurement System - DMS of the INRIM Time Laboratory

The Data Measurement System (DMS) of the INRIM Time Laboratory, is a measurement system composed by some instruments and controlled by a specically designed software that is used to measure and acquire the timing signals from all the atomic clocks as well as other devices of the laboratory, with respect to the reference Italian Time Scale, whose data need to be communicated to the BIPM (Bureau International des Poids et Mesures) or, more in general, to be constantly monitored. The system is able to measure also the status parameters of the atomic clocks and the environmental parameters of the rooms hosting all the instrumentation, thus permitting their constant check and monitoring. Recently, a big eort has been put in renewing and improving the DMS, both from the hardware and the software point of view. In this Technical Report a description will be provided of the DMS system and of all the interventions done to improve its functionalities.
