Page 76 ® Getting started R&S Spectrum Rider FPH Trying out the instrument Figure 3-9: USB connection 3.3 Trying out the instrument This chapter provides a short overview of the first steps of the measurements you can perform with the R&S Spectrum Rider.
Page 77 ® Getting started R&S Spectrum Rider FPH Trying out the instrument 3.3.1.1 Attenuating the signal You can attenuate the signal to a suitable level either manually or automatically. In case of automatic attenuation, the level of attenuation at the RF input depends on the current reference level.
Page 78 ® Getting started R&S Spectrum Rider FPH Trying out the instrument ● Using rotary knob While you can enter any number you want with the number keys, using the rotary knob is coupled to a certain step size in most cases.
Page 79 ® Getting started R&S Spectrum Rider FPH Trying out the instrument 3.3.1.3 Measuring CW signals A basic task for spectrum analyzers is to measure the level and frequency of sinewave signals. The following examples illustrate an effective way of performing these mea- surements.
Page 80 ® Getting started R&S Spectrum Rider FPH Trying out the instrument Setting the reference level The level at the top of the measurement diagram is called the reference level. To obtain the best dynamic range from the R&S Spectrum Rider, you should use its full level range.
Page 81 ® Getting started R&S Spectrum Rider FPH Trying out the instrument Measuring the frequency The trace consists of 711 measurement points (frequency points). The marker is always positioned on one of these measurement points. The R&S Spectrum Rider cal- culates the marker frequency from the frequency of the measurement point, the center frequency and the frequency span that have been set.
Page 82 ® Getting started R&S Spectrum Rider FPH Trying out the instrument 3.3.1.4 Measuring harmonics A spectrum analyzer is ideal to measure harmonic levels or harmonic ratios, because it can resolve different signals in the frequency domain. With marker functions, you can speed up the measurement tasks.
Page 83 ® Getting started R&S Spectrum Rider FPH Trying out the instrument The R&S Spectrum Rider opens an entry box to enter the start frequency. 4. Enter a start frequency of 50 MHz. 5. Confirm the entry with one of the unit keys.
Page 84 ® Getting started R&S Spectrum Rider FPH Trying out the instrument 3.3.2 Using a power sensor R&S Spectrum Rider option R&S FPH-K9 (order number: 1321.0709.02) option is required to operate the R&S Spectrum Rider in the power sensor mode. For highly accurate power measurements, you can connect one of the power sensors that are supported by the R&S Spectrum Rider.

Page 207 ® Spectrum analyzer mode R&S Spectrum Rider FPH Configuring spectrum measurements When demodulating an AM modulated signal, the R&S Spectrum Rider turns the video voltage into an audible sound. You should therefore set the reference level to about the level of the signal that you are demodulating.

Page 532 ® Appendix R&S Spectrum Rider FPH How a spectrum analyzer works 17 Appendix In this appendix, additional information on how a spectrum analyzer work is given. 17.1 How a spectrum analyzer works Basically, it is possible to measure and analyze RF signals either in the time domain or the frequency domain.
Page 533 ® Appendix R&S Spectrum Rider FPH 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.
Page 534 ® Appendix R&S Spectrum Rider FPH 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.
Page 535 ® Appendix R&S Spectrum Rider FPH 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.
Page 536 ® Appendix R&S Spectrum Rider FPH 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.
