Chapter 238
Activating FM
Follow these remaining steps to output the frequency-modulated signal.
1. Press
FM Off On.
The FM annunciator is activated indicating that you have enabled frequency modulation.
2. Press
RF On/Off.
The RF ON annuciator is activated, indicating that the signal is now available at the
RF OUTPUT connector.
Configuring ΦM
Using this procedure, you will learn how to create a phase-modulated RF carrier with the
following characteristics:
• RF output frequency set to 20.0 GHz
• RF output amplitude set to 0 dBm
•
Φ
M deviation set to 0.25
π
radians
•
Φ
M rate set to 30 kHz
Setting the RF Output Frequency
1. Press
Preset.
2. Press
Frequency > 20 > GHz.
The FREQUENCY area of the display now reads 20.000 000 000 00 GHz.
Setting the RF Output Amplitude
Press
Amplitude > 0 > dBm.
The AMPLITUDE area of the display now reads 0.00 dBm.
Setting the
Φ
M Deviation and Rate
1. Press the
FM/ΦM hardkey.
2. Press the
FM ΦM softkey.
The first level menu of ΦM softkeys is displayed.
