The first level menu of FM softkeys is displayed.

FM deviation becomes the active function and the preset value for FM deviation is displayed in the active entry area.

The new FM deviation is displayed below the FM Dev softkey. You should see 75.0000 kHz in the second line of the softkey label.

Setting the FM Rate

1.Press the FM Rate softkey.

2.Enter 10 using the numeric keypad and press the kHz softkey.

Turning On Frequency Modulation

The signal generator is now configured to output a 0 dBm, frequency-modulated carrier at

104.9MHz with the FM deviation set to 75 kHz and the FM rate set to 10 kHz. The shape of the waveform is a sinewave.

NOTE

Sine is the default selection for the FM Waveform softkey. Press More (1 of 2) to see

 

the softkey.

 

 

Follow these remaining steps to output the frequency-modulated signal:

1.Press the FM Off On softkey. FM toggles from Off to On. Notice, also, that the FM display annunciator is turned on, indicating that you have enabled frequency modulation.

2. Press RF On/Off.

Notice that the display annunciator changes from RF OFF to

 

RF ON. The modulated signal is now available at the

 

RF OUTPUT connector.
