Internal 3rd and 4th Source for 4-port R&S
ZNA
R&S
ZNAxx-B3
●
A two-port R&S
ZNA is always equipped with a single internal source. This source
can drive a single port at a time.
If two or more independent signals are needed (e.g. for
), then an external generator is required.
●
A four-port R&S
ZNA has at least two internal sources.
–
With two internal sources (default), the physical ports of a four-port VNA are
split into groups P1 = {1,2} and P2 = {3,4} such that source 1 can only drive
ports in P1 and source 2 can only drive ports in P2.
Independent signals require the source ports to reside in different port groups.
For example, you cannot use VNA ports 1 and 2 as independent source ports.
