b) use the "Disconnect" button in the "DUT Definition" tab to delete the port con-
nection
Change the logical VNA port numbering (R&S
ZNBT only)
The "DUT Definition" tab of the "Define Parallel Measurement" dialog allows to renum-
ber the logical VNA ports:
1. Activate the "DUT Definition" tab.
2. To number the logical ports in line with the physical ports, click "Identity 1-1"
For balanced ports, the lower of the two physical port numbers is selected.
3. To number the logical ports consecutively from bottom to top, click "Aligned
1,2,3..."
4. To assign a new number to a particular logical port, in the "DUT Definition" tab
a) select the VNA port
b) specify a new logical port number (less or equal than the number of physical
VNA ports) in the "Logical Port" field
Controls and Functions
The GUI functions are quite self-explanatory; their use is sufficiently explained in the
above procedures.
The remote control implementation of the "Multiple DUTs" feature introduces an addi-
tional port group layer, where a DUT's port group consists of the logical VNA ports that
are actually connected to this DUT.
Remote command:
SOURce<Ch>:GROup<Grp>:PPORts
SOURce<Ch>:GROup:COUNt?
SOURce<Ch>:GROup<Grp>:NAME
SOURce<Ch>:GROup<Grp>:DPORt:COUNt
SOURce<Ch>:GROup<Grp>:PPORt<PhyPort>:DPORt
SOURce<Ch>:GROup<Grp>:PORDer
Balanced Ports Tab
The "Balanced Ports" tab of the "Define Parallel Measurement" dialog allows to define
the balanced port configuration of the configured DUTs.
In order to modify the balanced port configuration, proceed as follows:
1. Select the related row in the DUT table.
The DUT perspective (upper left part of the dialog) now displays the selected DUT.
2. Activate the "Balanced Ports" tab.
3. To create a balanced port
a) in the DUT perspective, toggle select two single-ended ports
b) in the "Balanced Ports" tab use the "Balanced" button to create the balanced
port from the selected single-ended ports
