If the channel is set up for a particular measurement in the measurement setup dialog
(e.g. the Scalar Mixer Meas setup dialog), then a change in the "Port Settings" dialog
does not change the settings in the setup dialog. The firmware adapts this logic to
keep the settings in the setup dialog consistent.
Arb Frequency tab
Defines port-specific frequencies (arbitrary mode) and other port-specific source set-
tings.
Arbitrary mode requires software option R&S ZNA-K4, see Chapter 4.7.3, "Frequency
conversion measurements", on page 261.
If any of the port frequencies are changed from their preset values, the frequency con-
version mode is activated on pressing "Apply" or "OK" in the dialog. An "Arb" label
appears in the channel line. "Reset" plus "Apply" or "OK" deactivates the arbitrary
mode.
Channel base frequency
After a Reset, all port frequencies are set to the channel base frequency f
b
. For fre-
quency sweeps, f
b
corresponds to the unmodified sweep range. For power, time, and
CW mode sweeps, it is equal to the CW frequency. f
b
is defined by the "Stimulus"
parameters (see Chapter 5.8, "Stimulus softtool", on page 522).
