3.2 Output a modulated signal
In this section, we will show how to enable modulation by configuring the SSG to output an
AM modulated signal with the following characteristics: Carrier frequency is 1GHz, the
carrier amplitude is -10dBm, the AM modulation depth is 80%, the modulation frequency is
10 kHz, and the modulation waveform is a sine wave.
1. Restore factory settings
A) Press UTILITY or the touch screen to set System -> Setting -> Preset Type->
Default.
B) Press PRESET or reset the system settings to perform reset operations. Make the
frequency offset and the phase defaults 0.
2. Set the carrier frequency and the carrier amplitude
A) Press FREQ and enter 1GHz with the numeric keypad, or click the frequency input box
on the touch screen to pop up the keypad to input 1GHz on the keypad.
B) Press LEVEL, type -10 dBm with the digital keyboard, or click on the amplitude input
box on the touch screen, pop up the keyboard, and type – 10dBm on the keyboard;
3. Set the AM modulation parameters
Press the MOD or click the MOD function block on the touchscreen to enter the
amplitude modulation parameter setting interface.
A) Set the modulation waveform to be a sine wave;
B) Set the modulation depth to 80%;
C) Set the modulation frequency to be 10 kHz;
D) Set the AM state open;
4. Enable the RF modulation output
