Abstract

The pre-series of the last generation of fast digital integrators for magnetic measurements, the e-FDI, aimed at satisfying the more challenging requirements expected in the future, has been just developed and made available at CERN. The enhanced instrument improves the state of the art thanks to a high-performance analogue front-end, a new hardware for self-calibration, a finer time base speeding-up internal DSP operation, and a new peripheral bus controller for higher data throughput. The e-FDI is now undergoing the performance assessment tests and the metrological characterization. In this paper, after a short description of the e-FDI, main preliminary test results are reported and discussed.
