Creating an FM Signal

This procedure will show you how to conﬁgure the signal generator to output a frequency-modulated signal with the following characteristics:

•carrier frequency set to 104.9 MHz

•power level set to 0 dBm

•FM deviation set to 75 kHz

•FM rate set to 10 kHz

Setting the Carrier Frequency

1.Press Preset.

2.Press Frequency.

3.Enter 104.9 using the numeric keypad and press the MHz softkey.

This sets the signal generator to its factory-deﬁned instrument state.

Frequency becomes the active function and the preset value for frequency is displayed in the active entry area.

The new carrier frequency (104.900 000 00 MHz) is shown in both the FREQUENCY area and the active entry area of the display.

Setting the Power Level

1.Press Amplitude.

2.Enter 0 using the numeric keypad and press the dBm softkey.

Amplitude becomes the active function and the preset value for amplitude is displayed in the active entry area.

The new power level (0.00 dBm) is shown in both the AMPLITUDE area and the active entry area of the display.
