Optimizing the Display of Harmonics
The R&S Cable Rider ZPH places the markers on the other harmonics even if they are
outside of the display range.
1. Press the [MEAS] key.
2. Select the "Adjust Settings" softkey.
The R&S Cable Rider ZPH performs a measurement to determine the ideal refer-
ence level, frequency and span in order to display all harmonics.
8.1.7.3
Activating the Harmonics List
To see the exact frequency of the harmonic, you can activate the marker list that shows
the value for each harmonic or marker.
1. Press the [MARKER] key.
2. Select the "Set Marker" softkey.
The R&S Cable Rider ZPH opens a submenu to set the view list.
3. Select the checkbox for the "View List" menu item.
The R&S Cable Rider ZPH displays the marker list that contains the values for
each harmonic.

Measuring the AM Modulation Depth
The AM Modulation Depth measurement analyzes AM modulated signals and calcu-
lates the modulation depth of the signal using the measurement results. Note that the
measurement works properly only if you apply an AM modulated signal.
1. Press the [MEAS] key.
2. Select the "Meas Mode" softkey.
The R&S Cable Rider ZPH opens a submenu to select the measurement mode.
3. Select the "AM Modulation Depth"" menu item.
The R&S Cable Rider ZPH starts to measure the AM modulation depth.
After you have started the measurement, the R&S Cable Rider ZPH places three mark-
ers on the trace. The first marker is placed on the peak power level. The R&S Cable
Rider ZPH assumes that position as the level of the carrier. The second and third
markers are delta markers. These are placed symmetrically on the adjacent peak val-
ues to the left and right of the carrier.
