    ® Basic Operation R&S Cable Rider ZPH Identifying Cable Faults 4.5 Identifying Cable Faults One of the basic measurement tasks for the R&S Cable Rider ZPH is to find cable faults with the distance-to-fault (DTF) measurement. Test setup The test setup requires an R&S Cable Rider ZPH, an RF cable (for example R&S FSH- Z320, order number 1309.6600.00) and a calibration standard (for example R&S FSH- Z28/Z29, order number 1300.7810.03 / 1300.7610.03 or R&S ZN-Z103 order number 3586.9392.00)).
  • Page 77 ® Basic Operation R&S Cable Rider ZPH Identifying Cable Faults The R&S Cable Rider ZPH switches its operating mode. By default, the R&S Cable Rider ZPH shows the magnitude of the reflection (S11). You can also measure the distance to fault or the cable loss. 3.
  • Page 78 ® Basic Operation R&S Cable Rider ZPH Identifying Cable Faults 3. Select the cable model that you require from the list of cables. The R&S Cable Rider ZPH loads the cable model that will be taken in for consider- ation during the distance-to-fault measurement. You can also define new cable models on the R&S Cable Rider ZPH or with the R&S InstrumentView software and then transfer them to the R&S Cable Rider ZPH.
  • Page 79 ® Basic Operation R&S Cable Rider ZPH Identifying Cable Faults Calibrating the test setup Using the calibration kit (R&S FSH-Z28 or R&S FSH-Z29), the R&S Cable Rider ZPH performs a "Full 1-Port" calibration over its entire span with 2501 sweep points. Thus, it is not necessary to perform a new calibration after changing the frequency range or cable length.
  • Page 80 ® Basic Operation R&S Cable Rider ZPH Identifying Cable Faults In addition to the distance to fault measurement, the R&S Cable Rider ZPH also features a reflection measurement, for example to test impedance matching.

  • Page 602 ® Appendix R&S Cable Rider ZPH How a Spectrum Analyzer Works Applying the Fourier transform to the periodic square wave transforms it into the fre- quency domain. The spectrum analyzer would show the fundamental (or frequency of the square wave) and its harmonics. The spectrum analyzer uses a narrow bandpass filter for measurements in the fre- quency domain.
  • Page 603 ® Appendix R&S Cable Rider ZPH How a Spectrum Analyzer Works The first local oscillator is tuned with a sawtooth which simultaneously acts as the x deflection voltage for the display. In practice, synthesizer technology is used to gener- ate the frequency of the first local oscillator and for a digital display. The instantaneous sawtooth voltage therefore determines the input frequency of the spectrum analyzer.
  • Page 604 ® Appendix R&S Cable Rider ZPH How a Spectrum Analyzer Works larly useful when sine signals are to be measured in the vicinity of the spectrum ana- lyzer’s intrinsic noise. The sine signal produces a video signal that is a DC voltage. At the IF, however, the noise is distributed over the whole bandwidth or, in the case of the video signal, over half the bandwidth of the resolution filter.
  • Page 605 ® Appendix R&S Cable Rider ZPH How a Spectrum Analyzer Works used by the spectrum analyzer to determine the RMS value of the measured values. It is therefore a measure of the spectral power represented by a pixel. The sample detec- tor takes an arbitrary measurement value and displays it (in the Fig.
