5.18.5.5 Switch Matrix RF Connections dialog
The "Switch Matrix RF Connections" dialog allows you to define the RF connections
between the VNA and the switch matrices, and the test port numbering.
Access: System – [Setup] > "External Ports" > "RF Connections..."
Background information
Refer to section Chapter 4.7.29, "External switch matrices", on page 269.
Defining switch matrix RF connections typically involves the following steps.
1. Add one or more external switch matrices to the RF connection configuration.
These matrices must have been registered before; see Chapter 5.18.5.3, "External
Matrices dialog", on page 791 for details.
2. For each matrix VNA port (the "north" ports in the graphical representation), specify
the connected VNA port or define it as "Unused" if no such connection exists.
For every matrix, there must be at least one RF connection to the VNA.
3. Select Renumber Test Ports to load the default test port assignment.
Unusable matrix test ports are marked with an "x". If the result does not suit your
needs, consider the switchable paths of your matrix and adjust the matrix VNA port
connections (see Chapter 4.7.29.3, "RF connections and matrix connectivity",
on page 271). Then select "Renumber Test Ports" again.
You can tweak the resulting test port assignment by renumbering the test ports and/or
setting some of the matrix test ports to "Unused" (see "Edit Test Port Connection"
on page 799). Configuration errors are displayed in balloon popups appearing at the
lower left corner of the dialog.
