Configuring FM
In this example, you will learn how to create a frequency-modulated RF carrier.
To Set the RF Output Frequency
1. Press
Preset
.
2. Press

To Set the FM Deviation and Rate
1. Press the
FM/ Φ M
hardkey.
2. Press
FM Dev

.
3. Press
FM Rate
>
10
>
kHz
.
The signal generator is now configured to output a 0 dBm, frequency-modulated carrier at 1 GHz with a
75 kHz deviation and a 10 kHz rate. The shape of the waveform is a sine wave. (Notice that sine is the
default for the
FM Waveform
softkey. Press
More (1 of 2)
to see the softkey.)
To Activate FM
1. Press
FM Off On
to On.
2. Press
RF On/Off
.
The FM and RF ON annunciators are now displayed. This indicates that you have enabled frequency
modulation and the signal is now being transmitted from the RF OUTPUT connector.
