The V545 is a generalized- DSP-based sinewave processor intended for both simulation and acquisition of LVDTs, RVDTs, synchros, and resolvers. 24 generalized, isolated channels are provided. Each channel can be a signal source or a measurement input. Users can program any desired relationship between input and output channels, allowing simulation and measurement of a wide range of inductive transducers, using internal or external excitation.

Per-channel features include true RMS AC measurement, frequency measurement, programmable phase shift, and a versatile phase-sensitive detector.

Plugin transformers allow optional voltage input/output ranges. Software transformer ID is provided.
