Analog Modulation

Configuring AM

Configuring AM

In this example, you will learn how to generate an amplitude-modulated RF carrier.

To Set the Carrier Frequency

1.Press Preset.

2.Press Frequency > 1340 > kHz.

To Set the RF Output Amplitude

Press Amplitude > 0 > dBm.

To Set the AM Depth and Rate

1.Press the AM hardkey.

2.Press AM Depth > 90 > %.

3.Press AM Rate > 10 > kHz.

The signal generator is now configured to output a 0 dBm, amplitude-modulated carrier at 1340 kHz with

the AM depth set to 90% and the AM rate set to 10 kHz. The shape of the waveform is a sine wave. Notice that sine is the default selection for the AM Waveform softkey, which can be viewed by pressing (More 1 of 2).

To Turn on Amplitude Modulation

Follow these remaining steps to output the amplitude-modulated signal.

1.Press the AM Off On softkey to On.

2.Press the front panel RF On Off key.

The AM and RF ON annunciators are now displayed. This indicates that you have enabled amplitude modulation and the signal is now being transmitted from the RF OUTPUT connector.
