Detecting harmonics
1. Press the [PRESET] key.
The R&S Cable Rider ZPH is reset to its default state.
After the preset, the R&S Cable Rider ZPH 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 the [FREQ/DIST] key.
3. Select the "Start" softkey at the "Measurement footer bar".
The R&S Cable Rider ZPH 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.
6. Select the "Stop" softkey at the "Measurement footer bar".
The R&S Cable Rider ZPH opens an entry box to enter the stop frequency.
7. Enter a stop frequency of 250 MHz.
8. Confirm the entry with one of the unit keys.
The R&S Cable Rider ZPH displays the frequency spectrum in the range from 50
MHz to 250 MHz. This frequency range visualizes the signal itself at 100 MHz and
the second harmonic at 200 MHz.
