The default values for the balanced port reference impedances are derived from the default reference
impedance of the physical analyzer ports (Z
0
= 50
):
•
The default value for the differential mode is Z
0d
= 100 = 2*Z
0
.
•
The default value for the common mode is Z
0c
= 25 = Z
0
/2.
Remote control:

Physical Port
Shows and/or defines the properties of the physical (unbalanced) ports of the analyzer.
•
# is the test port number of the analyzer as shown on the front panel. External generators and
power meters configured in the
System Configuration dialog are also shown in the list of
physical ports.
•
Instrum. shows the network analyzer type (e.g. ZVA8, ZVA24). The types of external
generators and power meters are also displayed in this column.
•
Connector opens a drop-down list to select the connector type An (f) behind the connector
type denotes female connectors, an (m) denotes male connectors. Symmetric (sexless)
connectors (e.g. PC7) are not labeled. User-defined connectors can be added or removed in
the
Available Connector Types dialog, which is opened from the Channel – Calibration –
Calibration Kits dialog. at the port and its gender. If Same Connector at All Ports is active, the
connector types at all ports (but not their gender) are always adjusted to the current selection.
•
Ref. Impedance shows the adjustable complex reference impedances of the physical port. If a
balanced port configuration is active the reference impedance settings for all ports are
displayed in the
Logical Port section.
