Remote command:
[SENSe<Ch>:]FREQuency:IMODulation:LTONe

For a 2-port R&S
ZNA, the upper tone must be provided by an
.
●
For a 4-port R&S

Remote command:
[SENSe<Ch>:]FREQuency:IMODulation:UTONe
Combiner Configuration
Opens the "Combiner Configuration" dialog that allows you to tell the analyzer how you
combine the lower and upper tone. The lower tone port is always the one on the left.
"External
(Port)"
Use the signals of the test ports and combine them externally (see
graphic above).
With this configuration, the two-tone signal is available at the output
of the combiner. This allows you to measure intermodulation products
at the DUT output, but not at the DUT input.
