Add/delete DUTs manually (R&S
ZNBT only)
1. Use the "Add" button to introduce a new DUT. This action is active if and only if
there are unconnected VNA ports.
2. To remove an existing DUT from the configuration, select the related row in the
DUT table and select "Delete".
Modify an existing DUT (R&S
ZNBT only)
The DUT table allows to rename an existing DUT (R&S
ZNB and R&S
ZNBT), to
define its physical ports and drive port order (R&S
ZNBT only).
1. Locate the related row in the DUT table.
2. In the "DUT" column specify the DUT's name.
3. In the "Port Count" column change the number of ports as needed.
Increasing the number of ports creates additional DUT ports together with connec-
tions to spare VNA ports, if available.
Decreasing the number of DUT ports deletes the highest numbered physical DUT
ports along with their VNA connections, if any. Balanced ports are resolved if one
of their constituent physical ports is removed.
4. In the "Port Order" column define the drive port order of the related DUT. "Auto"
lets the VNA firmware select the (default) drive port order. An explicit drive port
ordering can be specified as a complete comma-separated list of the respective
DUT port numbers
1, ..., "Port Count"
(see
above).

Define physical port connections (R&S
ZNBT only)
In general the auto-generated port connections between VNA and DUTs have to be
reconfigured to a certain extent.
1. Select the related row in the DUT table (lower left part of the dialog).
The DUT perspective (upper left part of the dialog) now displays the selected DUT.
2. Activate the "DUT Definition" tab.
3. To create/modify a port connection
a) in the DUT perspective, toggle select the DUT port to be (re-)connected
b) in the "DUT Definition" tab, toggle select the VNA port to be (re-)connected
c) use the "Connect" button in the "DUT Definition" tab to create the port connec-
tion between the selected ports
If the VNA port was previously connected, this connection is disconnected auto-
matically.
4. To delete an existing port connection
a) in the DUT perspective, toggle select the VNA port to be disconnected
