	The superconducting magnet test facility at CERN, (SM18), has been using the Automatic Quench Analysis (AQA) software to analyse the quench data during the Large Hadron Collider (LHC) magnet test campaign. This application was developed using LabVIEW in the early 2000's by the Measurement Test and Analysis section (MTA) at CERN. During the last few years, the SM18 has been upgraded for the High Luminosity LHC (HL-LHC) magnet prototypes. These HL-LHC magnets demand a high flexibility of the software. The new requirements were that the analysis algorithms should be open, allowing contributions from engineers and physicists with basic programming knowledge, execute automatically a large number of tests, generate reports and be maintainable by the MTA team. The paper contains the description, present status and future evolutions of the new AQA soft-ware that replaces the LabVIEW application.

	Particle accelerators are complex machines with fast and high power absorption peaks. Power quality is a critical aspect for correct operation. External and internal disturbances can have significant repercussions causing beam losses or severe perturbations. Mastering the load and understanding how network disturbances propagate across the network is a crucial step for developing the grid model and realizing the limits of the existing installations. Despite the fact that several off-the-shelf solutions for real time data acquisition are available, an in-house FPGA based solution was developed to create a distributed measurement system. The system can measure power and power quality on demand as well as acquire raw current and voltage data on a defined trigger, similar to a distributed oscilloscope. In addition, the system allows recording many digital signals from the high voltage switchgear enabling electrical perturbations to be easily correlated with the state of the network. The result is a scalable system with fully customizable software, written specifically for this purpose. The system prototype has been in service for two years and full-scale deployment is currently ongoing.
