Setting the FM Deviation | Agilent Technologies E4400-90326 instruction

Getting Started

Creating an FM Signal

Setting the FM Deviation

1.Press FM/φM.

2.Press the FM Dev softkey.

3.Enter 75 using the numeric keypad and press the kHz softkey.

ESG Family Signal Generators

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.

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

The new FM rate is displayed below the FM Rate softkey. You should see 10.0000 kHz in the second line of the softkey label.

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.
