If the VNA port was previously connected, this connection is disconnected auto-
matically.
4. To dissolve one or more balanced ports
a) in the DUT perspective, for each balanced port to be dissolved, toggle-select
one of its constituent DUT ports
b) use the "Single" button in the "Balanced Ports" tab to dissolve all related bal-
anced ports
Reference Impedance Tab
The "Reference Impedance" tab of the "Define Parallel Measurement" dialog allows 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).
The DUT perspective (upper left part of the dialog) now displays the selected DUT.
2. Activate the "Reference Impedance" tab.
3. In the DUT perspective, toggle select (one of) the related DUT port(s).
4. Use the controls in the Reference Impedance tab to specify the impedance set-
tings. The user interface is identical to the one described in
Frequency Offset Tab
The "Frequency Offset" tab allows to activate
Parallel Measurements on Multiple DUTs
and to define a "Minimum Offset" between the stimuli.
To get access to the "Frequency Offset" configuration, create multiple DUTs (on the
R&S
ZNB set "Parallel Measurement" to "Enabled") and activate the "Frequency Off-
set" tab.
It is essential to perform the calibration with the same "Frequency Offset" settings as
for the actual measurement; otherwise the calibration is deactivated ("Cal Off"). The
provides concise information on these "Frequency Offset"
mismatches, should they occur.
