Ensuring the performance and reliability of these magnets requires high-precision measurements of their electrical properties during testing. To meet the R&D program needs of the new superconducting magnet technology, an accurate and generic voltage measurement system was developed after the testing and validation campaign of the LHC magnets. The system was based on a set of digital multimeter (DMM) cards installed in a PXI modular chassis and controlled using CERN’s in-house software development. It allowed for the measurement of the electrical properties of the magnet prototypes during their study phase. However, during the renovation of the magnet test benches and in preparation for the HL-LHC magnet series measurement, some limitations and instabilities were discovered during long recording measurements. As a result, it was decided to redesign the measurement system. The emergence and promises of the new PXIe platform, along with the requirement to build eight new systems to be operated similarly to the existing four, led to a complete redesign of the software. This article describes the various software techniques employed to address platform compatibility issues and significantly improve measurement accuracy, thus ensuring the reliability and quality of the data obtained from the HL-LHC magnet tests.
