Generating a Phase Modulated Signal
The signal generator generates phase modulated (FM)
signals with the following basic characters:
Operation Example
Assume that you are going to generate a FM signal with the
following characters:
• Carrier frequency of 1 GHz, amplitude of –10 dBm
• FM deviation of 7.3 rad
• FM rate at 10 kHz
Refer to the following to configure your signal generator:
1 Pressing presets the signal generator
2 Pressing
> 1 > GHz sets the CW frequency to 1 GHz
3 Pressing
> –10 > dBm sets the CW amplitude to –10 dBm
4 Pressing enters the FM submenu
5 Pressing FM Deviation > 7.3 > rad sets FM deviation to 7.3 rad
6 Pressing FM Rate > 10 > kHz sets FM rate to 10 kHz
7 Pressing FM On off enables FM
8 Pressing RF On/Off to On enables FM signal output.
For key reference, please refer to “Phase Modulation” on
page 67.
