DUT Definition tab
Modify an existing DUT
The DUT table allows you to rename an existing DUT.
1. Locate the related row in the DUT table.
2. In the "DUT" column, specify the DUT's name.
Controls and Functions
The GUI functions are 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. A DUT's port group consists of the logical VNA ports that are
connected to this DUT.
Remote command:
SOURce<Ch>:GROup:COUNt?
SOURce<Ch>:GROup<Grp>:NAME
Balanced Ports tab
The "Balanced Ports" tab of the "Define Parallel Measurement" dialog allows you to
define the balanced ports 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 DUT ports.
b) In the "Balanced Ports" tab, select "Balanced" to create the balanced port from
the selected DUT ports.
4. To dissolve one or more balanced ports:
a) In the DUT perspective, for each balanced port you want to dissolve, toggle-
select one of its constituent DUT ports.
b) In the "Balanced Ports" tab, select "Single" to dissolve all related balanced
ports.
Reference Impedance tab
The "Reference Impedance" tab of the "Define Parallel Measurement" dialog allows
you to set the reference impedance for balanced and unbalanced DUT ports.
To change the reference impedance for a particular DUT port, proceed as follows:
1. Select the related row in the DUT table (lower left part of the dialog).
