    Matrix building blocks Instrument functions The single function of a switch matrix R&S ZN-Z84 is to dynamically establish RF connections between its VNA ports (statically connected to the RF ports of the VNA) and its test ports (statically connected to the DUT), applying a passive load match to currently unconnected ports.

  • Page 37 ZN-Z84 RF connections and matrix connectivity Example: Consider a fully equipped R&S ZN-Z84, where the matrix VNA ports of the left submatrix cannot be connected to the test ports of the right submatrix and vice versa. If none of the two VNA ports of a submatrix is connected, obviously no connection between the VNA and the submatrix's test ports can be established and hence neither reflection nor transmission measurements are possible.

  • Page 38: Multiple Paths: Precision Versus Speed

    However, as long as a second connection between the VNA and this submatrix is missing, "intra-submatrix" transmission measurements are still impossible.

  • Page 39 To see the difference between the two optimizations, again consider a DUT with 6 unbalanced ports, connected to a 2-port analyzer via the R&S ZN-Z84 base unit without extension. If all S-parameters shall be measured, at least 6*5/2 succes- sive matrix switching procedures are required (one for each pair of test ports) and the speed optimization would choose one of these minimum solutions.
