"Use Coupler
as Combiner"
This configuration does not require an external combiner, but pro-
vides a reduced dynamic range. It combines the signals of the lower
tone and upper tone sources using the directional coupler of the
upper tone port as combiner:
With this configuration, the two-tone signal is available at test port 1.
The intermodulation quantities can be measured at the DUT input or
at the DUT output.
"Internal"
If the R&S ZNA is equipped with an Internal combiner (R&S ZNAxx-
B21y), then:
●
For a 2-port instrument (with R&S ZNAxx-B212), the source sig-
nals of port 1 and port 2 can be combined internally
●
For a 4-port instrument (with R&S ZNAxx-B213), the source sig-
nals of port 1 and port 3 can be combined internally
The combined signal is output to port 1.
Remote command:
SOURce<Ch>:COMBiner
Receiver Inputs ← Combiner Configuration
Defines the receiver signal paths for the lower- and upper-tone ports.
