A 2- to 20-mA signal conditioner can power a new line of modern, pre-polarized condensor microphones. Using standard coaxial cables, these pre-polarized units can be utilized with the same constant-current ICP accelerometers. This enables the microphones to be put alongside the accelerometers in the same test fixture, minimizing setup time.
