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
