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.
A signal generator, e.g. R&S SMBV provides the signal source.
Test setup
Connect the RF output of the signal generator to the RF input of the R&S Spectrum
Rider.
Signal generator settings:
●
Frequency: 100 MHz
●
Level: -20 dBm
Detecting harmonics
1. Press [PRESET] key.
The R&S Spectrum Rider is reset to its default state.
After the preset, the R&S Spectrum Rider displays the frequency spectrum over its
full frequency span.
At 100 MHz, the generator signal is displayed as a vertical line. In addition, you can
see the harmonics as smaller vertical lines at frequencies that are multiples of 100
MHz. To measure the second harmonic ratio, decrease the span.
2. Press [FREQ] key.
3. Select the "Start" softkey at the "Measurement footer bar".
