Functional Description (contd.)

7. To Generate the
Modulated
Waveform

Use this button to generate modulated waveform. The Generator can
generate AM, FM, ASK, FSK and PM modulated waveforms. Modulating
parameters vary with the types of the modulation :

•

In AM, users can set the source (internal/external), depth, modulating
frequency, modulating waveform and carrier waveform

•

In FM, users can set the source (internal/ external),frequency
deviation, modulating waveform and carrier waveform

•

In ASK, users can set the source (internal/external), modulating
waveform and carrier waveform

•

In FSK, users can set the source (internal/external), frequency range,
key frequency, modulating waveform and carrier waveform

•

In PM, users can set the source (internal/external),phase deviation,
modulating frequency, modulating waveform and carrier waveform.

We will cover how to set these parameters in details according to the
modulation types.
