9.3.6 Measurement Example: Measuring Harmonics Using Marker Func-

tions

This measurement example describes how to measure harmonics using the provided

marker functions. Note that this task can be performed much simpler using the Har-

monic Distortion measurement (see Chapter 7.10, "Harmonic Distortion Measure-

ment", on page 312).

Signal generator settings (e.g. R&S SMW):

Frequency: 128 MHz

Level: +15 dBm

Procedure:

1. Preset the R&S FSW.

2. Set the center frequency to 128 MHz.

3. Set the span to 100 kHz.

4. Select "Auto Level".

The R&S FSW displays the reference signal with a span of 100 kHz and resolution

bandwidth of 1 kHz.

5. Switch on the marker by pressing the [MKR] key.

The marker is positioned on the trace maximum.

6. Set the measured signal frequency and the measured level as reference values:

a) Press the [MKR FUNC] key

b) Press the "Reference Fixed" softkey.

The position of the marker becomes the reference point. The reference point level

is indicated by a horizontal line, the reference point frequency with a vertical line.

At the same time, the delta marker 2 is switched on.
