Switch Module 2x6

At the "south" the 2x6 switch modules implement the test ports. At the "north"
they are either directly connected to the VNA ports (in R&S

ZN-Z84 Base Units

without extensions) or to one or two 1x4 switch modules.

To prevent reflections caused by misadjustment, 50 Ω terminating resistors are
connected to unused outputs.
