For a two-port R&S
ZNA, a test setup with an external generator and an external
combiner is required.

Lower Tone
The lower tone signal is generated at port 1, the upper tone is provided by the external
generator. Both signals are combined externally and fed to the DUT input. The intermo-
dulation quantities can be measured at the DUT output (transmitted wave b2). It is pos-
sible to interchange the ports no. 1 and 2.
For a 4-port R&S
ZNA, you can use any combination of analyzer ports that are sup-
plied by different internal sources to generate the lower and upper tones. In the follow-
ing example, port 3 replaces the external generator.
