Rohde and Schwarz FPC-K42 – Vector Reflection Measurement (for FPC1500 only)

One port vector network analyzer (S11)

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 engineering, 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 S11 measurements.

Another application of S11 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.

Smith chart

The Smith chart visualizes the complex S11 reflection. In other words, it shows how resistive, capacitive or inductive a load is across the frequency range. With this information, it is easy to tune network components to optimize impedance matching.
