How cables and connectors impact measurement uncertainty Application Note More often than perhaps known, the outcome of a calibration procedure can depend on the technician knowing which cables and connectors are appropriate for the calibration setup. Choosing the wrong cables and/or connectors can have a significant impact on the overall uncertainty of the setup or calibration system. If you're new to dc and low frequency ac calibration, it's important to understand the impact connectors and cables have on overall measurement uncertainty, as well as the importance of cable maintenance. Cables, connectors, and these influences are in series with traceability the signal circuit, and others are in parallel. Because a calibrator must be Moving from left to right in the electrically connected to the unit diagram, possible contributions under test (UUT), there is at least to total measurement uncertainty one pair of connectors involved are: on both. These electrical cables
