We will test it as the customer prefers, but for design verification purposes, or if there is any question as to the validity of the results, we prefer to use a specially designed coaxial test fixture that mounts onto the end of the receptacle and provides a continuous and well matched 50 ohm impedance.

We occasionally have customers specify that we test a receptacle using chip resistors; either a single 50 ohm chip resistor, two 100 ohms chips or even four 200 ohm chips in parallel.

This may require that we need to make up additional test pieces for test and verification, as this will not work with a tab style connector.

Receptacles can present problems due to the fact that their output may be anything from a diameter to a flat tab and standards for these varied outputs do not exist.
