Internal VSWR bridge
Due to its unique design utilizing an internal VSWR bridge,
the R&S®FPC1500 can perform one-port vector reflec-
tion measurements. This feature makes it possible to take
impedance measurements on RF antennas or RF circuits
with the Smith chart display or distance-to-fault measure-
ments to detect faulty locations over a long RF cable.
Thanks to the built-in internal VSWR bridge, it is no longer
necessary to mount/dismount an external VSWR bridge
when switching between the measurement modes, e.g.
from the spectrum analyzer mode to the vector network
analyzer mode or vice versa.
Network analyzer
One-port vector network analyzer (S
11
)
One-port vector network analysis is used for impedance
matching on components or networks, such as antennas
or filters.
Impedance matching is an integral part of RF engineer-
ing, used to adjust transmission bandwidth and balance
power transmission. With its integrated VSWR bridge,
the R&S®FPC1500 becomes a one-port vector network
analyzer that can perform all of these S
11
measurements.
Another application of S
11
measurements is distance-to-
fault (DTF) measurement. It displays RF return loss or
VSWR data versus distance. It reveals poor connections,
damaged cables or faulty antennas quickly and provides
information on physical distance from the calibration point
to the faulty location.
Should calibration be needed to eliminate the effects
of additional cables or adapters used to connect the
analyzer to the device under test (DUT), the R&S®ZN-Z103
automatic calibration unit performs the calibration in a
single step.
