Shielded 2T extension
As shown in Figure 3-13, the 4TP configuration is terminated and the extension cables configure a
modified 3T (shielded 2T). The two outer shielding conductors are connected together at each end of
the cable. This decreases the magnetic field induced by the inner conductors. This technique is used
in the higher frequency region, up to 15 MHz. The residual impedance of the cables will be directly
added to the measurement result, but can be an insignificant error source if the DUT’s impedance
is greater than the impedance due to the residuals. For the actual connection, a connector
plate (Agilent part number 16032-60001) supplied with Agilent test cables can be used as shown in
Figure 3-13.
