INTernal | EXTernal | B16external | COUPler
INTernal
The signals are combined using the
.
This is only possible for four-port models and for ports 1 and 3. It
requires option R&S
ZNAxx-B213.
EXTernal
The test port signals are combined externally. The two-tone sig-
nal is available at the output of the combiner.
B16external
The source out signal (direct access) of the lower tone port and
the signal of the upper tone test port are combined externally.
The combined signal is fed to the source in (direct access) of the
lower tone port and is available at the lower tone test port.
COUPler
With this configuration the signals of the lower tone and upper
tone sources are combined using the directional coupler of the
upper tone port. The combined signal is available at the lower
tone test port.
Options:
R&S
ZNA-K4 for intermodulation, R&S
ZNA-K9 for two-tone
group delay measurements
R&S
ZNAxx-B16 for B16external and COUPler signal paths
