ZNB/ZNBT
1402User Manual 1173.9163.02 ─ 62
At transaction start the R&S ZNB/ZNBT creates an in-memory copy of the active con-
figuration and strips off all RF conncections from this copy. Subsequent RF connection
actions such as SYSTem:COMMunicate:RDEVice:SMATrix<Matr>:CONFigure:
MVNA and SYSTem:COMMunicate:RDEVice:SMATrix<Matr>:CONFigure:MTESt
operate on the copy.
However, the copy contains the very same switch matrices as the original, so the ade-
quate set of matrices has to be selected beforehand (using manual control or the
remote command INSTrument:SMATrix).
If a previous transaction is active, it will be silently rolled back.
Note that a redefinition of the physical VNA ports (see [SENSe:]UDSParams<Pt>:
PARam) causes a factory reset and deletes all switch matrix RF connections. So the RF
configuration for switch matrices has to be done after the port redefinition.
Example:
:INSTrument:SMATrix OFF
Remove all switch matrices from the RF configuration.
:SYSTem:COMMunicate:RDEVice:SMATrix:DELete
Unconfigure all switch matrices, i.e. remove them from the list of
configured devices.
:SYSTem:COMMunicate:RDEVice:SMATrix1:DEFine '',
'ZV-Z82-30', 'LAN', '192.168.0.42'
Register a single switch matrix of type ZV-Z82-30 (with two 2x5
submatrices).
:INSTrument:SMATrix ON
Add the matrix to the RF configuration, performing a default
assignment of VNA ports and test ports.

STARt
Start a manual RF connection configuration.
:SYSTem:COMMunicate:RDEVice:SMATrix1:CONFigure:
MVNA 1,1,3,2,2,3,4,4
Define non-default matrix-VNA port connections: matrix port 1 to
VNA port 2, matrix port 3 to VNA port 2, matrix port 2 to VNA
port 3 and matrix port 4 to VNA port 4 (default is
1,3,2,4,3,1,4,2).
:SYSTem:COMMunicate:RDEVice:SMATrix1:CONFigure:
MTESt 1,1,2,2,9,3,10,4
Configure 4 matrix test ports only: matrix test port 1 is test port
1, matrix test port 2 is test port 2, matrix test port 9 is test port 3
and matrix test port 10 is test port 4.
:SYSTem:COMMunicate:RDEVice:SMATrix:CONFigure:
