RF connections; in "get direction" it queries whether at least one RF connection to a
switch matrix is configured.
Parameters:
<Boolean>
ON | 1 (setting) – adds all registered switch matrices to the RF
configuration, performing a default assignment of VNA ports and
test ports.
OFF | 0 (setting) – removes all switch matrices from the RF con-
figuration

INSTrument:TPORt:COUNt?

In absence of switch matrices, i.e. if no RF connection to a switch matrix is configured,
this is identical to the number of VNA ports (see
).
