Fig. 3 shows the pin assignment of the D-Sub-25 connectors of an R&S ENY81 ISN
basic network with four symmetrical pairs. The drawing in the middle shows an RJ-45
jack with EIA/TIA T568B pin assignment. The 1 mm socket area shown on the right
can be used for any desired assignment of the RJ-11/RJ-45 jacks.

3 Functional Test of the R&S ENY81
Asymmetrical impedance and phase, voltage division factor, longitudinal conversion
loss and decoupling attenuation can be measured using a vector network analyzer and
the R&S ENY-FTS functional test set (order no. 1309.8703.03). If impedance is not
measured, a test receiver with a tracking generator together with the R&S ENY-FTS
functional test set will be sufficient. The R&S ENY-FTS comes with a detailed
description of the calibration and test procedure.
