The expected performances are in line with the requirements and, in the cases where this was not possible, approval of more » trade-offs was sought and received from the end users. This work covered the entire design process of the signal conditioner, resulting in a project ready for manufacturing. Basic low level routines for hardware access were defined. An embedded board was selected for controlling and interfacing the signal conditioning circuitry with the instrumentation network. The printed circuit boards were laid out and routed using a CAD software and focusing the design on maximum electromagnetic interference immunity. Using a top-down approach, all the circuits were designed and their expected performances were theoretically predicted and simulated. The design started with a given set of requirements. This thesis is part of an upgrade project for replacing obsolescent automated test equipment belonging to the Fermilab Magnet Test Facility. Software design was started with the definition of routine procedures. Other system components were chosen from those available on the market. A 10-channel signal conditioning circuit featuring bucking capabilities was designed from scratch and implemented to the level of the printed circuit board layout. This thesis describes the design of a remotely-programmable signal conditioner for the harmonic measurement of accelerator magnets.
