5.7.26 External Generators
The connection of an external generator to the R&S ZNB/ZNBT can serve different
purposes.
●
Extended measurement functionality: Each external generator represents an addi-
tional source port. External generators increase the number of RF input signals for
the DUT. A typical example is a mixer measurement with a 2-port analyzer, where
an external generator provides the LO input signal.
