For a 4-port R&S ZNA with four sources, the mixer's LO signal can also be provided by
the VNA.
Two-tone generation and combination
To generate a two-tone signal, two independent RF signal sources are required.
On a two-port R&S ZNAxx, two internal sources are only available with option
R&S ZNAxx-B52 Internal 2nd source and 2nd LO generator for 2-port R&S ZNA.
For a R&S ZNA that is not equipped with Internal combiner or with Direct generator/
receiver access (R&S ZNAxx-B16), lower and upper tone must be combined from the
RF ports on the analyzer and connected external generators. An external combiner is
required.
