Rohde and Schwarz FPH-K43 - Receiver Mode Option for FPH

Equipped with option FPH-K43, you can perform receiver and channel measurements (or scans) with your R&S Spectrum Rider.

In receiver mode, the R&S Spectrum Rider measures the power level of a particular frequency or a customized set of frequencies instead of sweeping over (parts of) the frequency spectrum. The R&S Spectrum Rider shows the scan results in result displays that have been designed for such measurement tasks.

The receiver mode also adds the necessary functions like bandwidths or detectors to perform measurements according to CISPR.

Performing Single Frequency Measurements

The R&S Spectrum Rider shows the result of the single frequency measurement in a result display that contains three main elements.

• Measurement (or receive) frequency
• Power level measured at the receive frequency
• Horizontal bar graph that graphically represents the currently measured power level

The R&S Spectrum Rider shows the result display for single frequency measurements.

Performing Frequency Scans

Compared to single frequency measurements, frequency scans perform a measurement on a particular set of receive frequencies. The scan measures only those frequencies that are defined in the frequency range. The space between the receive frequencies is not considered in the measurement.

The R&S Spectrum Rider shows the results for a frequency scan in a graphical result display. The horizontal axis in that display represents the frequency spectrum covered by the scan. The vertical axis represents the power levels.

The power levels for each frequency contained in the scan are represented by a vertical line at the receive frequencies that have been measured. This type of display emphasizes the fact that the scan measures single receive frequencies only and not the frequencies between those receive frequencies.
