6.
Press F3 to set AM Frequency. The range is 2 mHz～20 kHz (Internal source
only).
7.
Press F4 to set Mod Depth. The range is 0%～100%.
Term Explanation
AM Frequency:
The frequency of modulating waveform.
Mod Depth:
The Amplitude Range of modulating waveform. In the 0% Modulation, the output
amplitude is the half of the set one. In the 100％ Modulation, the output amplitude is
the same with the set one. For an external source, the depth of AM is controlled by the
voltage level of the signal connected to the Modulation In connector in the rear panel.
+5V corresponds to the currently set depth 100%.
5.27. FM (Frequency Modulation)
The modulated waveform consists of two parts: the Carrier Waveform and the Modulating
Waveform. The Carrier Waveform can only be Sine. In FM, the frequency of the Carrier
Waveform varies with the instantaneous voltage of the modulating waveform. The user
interface of the FM is shown as below.
