Measuring Harmonics
The following example shows a basic measurement of the second and third harmonic of a + 10 dBm, 1 GHz
carrier using delta markers:
1. Preset the analyzer using the Preset button.
2. On the analyzer, set up the following:
Center Frequency: 2 GHz
Span: 3 GHz
Reference Level: 10 dBm
RBW: 30 kHz
3. Turn on Marker 1 and press the Mkr–>Pk icon, then turn on the Marker Table.
4. Turn on Marker 2, set it as a Delta Marker, then press the Next Peak icon until the marker lands on the
second harmonic.
5. Turn on Marker 3, set it as a Delta Marker, then press the Next Peak icon until the marker lands on the
third harmonic.
The display should look like the one in the figure below:
