Setting Up Internally-Generated Amplitude Modulation
Using this procedure, you will learn how to generate an amplitude-modulated
signal with the following characteristics:
• carrier frequency set to 1340 kHz
• power level set to 0 dBm
• AM depth set to 90%
• AM rate set to 10 kHz
Setting the Carrier Frequency
1. Press Preset to return the signal generator to the factory-defined instrument state.
2. Press the front panel
Frequency key. Frequency becomes the active function and the
normal preset value for frequency is displayed in the active entry area.
3. Enter 1340 kHz using the numeric keypad and pressing the
kHz terminator softkey. The
new carrier frequency is shown in the frequency area of the display. You should see
1.340 000 00 MHz.
Setting the Power Level
1. Press the front panel Amplitude key. Amplitude becomes the active function and the
normal preset value for amplitude is displayed in the active entry area.
2. Enter 0 dBm using the numeric keypad and pressing the
dBm terminator softkey. The
new power level is shown in the amplitude area of the display. You should see
0.00 dBm.
Setting the AM Depth
1. Press the front panel AM key. The first level menu of softkeys is displayed.
2. Press the
AM Depth softkey. AM depth becomes the active function and the normal
preset value for AM depth is displayed in the active entry area.
3. Enter 90% using the numeric keypad and pressing the
% terminator softkey. The new
AM depth is displayed below the
AM Depth softkey. You should see 90.0 % in the
second line of the softkey.
