APC 3.5 mm female connector. Sources stimulus signals for the DUT and
receives response signals from the DUT. Frequency range is determined
by the network analyzer module model.
SMA female connector. If the network analyzer module is not configured
with another module, the connector is terminated with a 50 ohm load. If
the module is configured with a module in an adjacent slot, the connector
receives the LO signal from the configured module.
SMA female connector. If the network analyzer module is not configured
with another module, the connector is terminated with a 50 ohm load. If
the analyzer module is configured with a module in an adjacent slot, the
connector provides the LO signal to the configured module.
SMB female connector. A 10 MHz external reference signal supplied to
this port can be used as the instrument frequency reference instead of the
internal frequency reference. To activate this feature on the soft front
panel, select Utility > System > Configure > External Reference.
