- Abstract:
- Resistive dividers find application in instrumentation because they allow fast and precise scaling-down of the applied signal input to an appropriate level of the processing electronics. Furthermore, among the applications where both wideband and accuracy requirements are demanding, resistive dividers employed as fixed-voltage ratio standards are widely used. Recently, at INRIM, coaxial voltage dividers suitable to be used in specific tasks of EU and National co-founded projects have been developed. Series-parallel type of dividers have been studied and built. Besides, methods for adjusting and calibrating their ratio, frequency response and phase difference have been analysed and experimented. Some aspects of the developed traceability chain and some examples of calibration results are given.
