7.4.5 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 5.10, "Harmonic Distortion Measurement",
on page 269).
Signal generator settings (e.g. R&S FSW SMU):
Frequency: 128 MHz
Level: - 25 dBm
Procedure:
1.
Preset the R&S FSW.
2. Set the center frequency to 128 MHz.
3. Set the span to 100 kHz.
The R&S FSW displays the reference signal with a span of 100 kHz and resolution
bandwidth of 1 kHz.
4. Switch on the marker by pressing the MKR key.
The marker is positioned on the trace maximum.
5. 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.
