Follow the above steps to generate the desired FM waveform. The modulation parameters page
after the setup is shown below. Note that since the modulating waveform frequency, shape, and
modulation depth are entirely determined by the external modulating input, the relevant
parameters are not displayed on the setup page.
The waveform of the AM output is as follows:(red trace. The green trace is the modulating
waveform).
Application example: Generate a PWM waveform with another channel as the
modulation source, with the following parameters
Carrier frequency = 1 MHz, pulse width = 500 ns
Modulating waveform = Sine, frequency = 100 kHz, pulse width deviation = 400 ns
1. PWM modulation is only supported when the carrier is Pulse. Set the carrier to Pulse
and the frequency to 1 MHz on the parameter setting page of the carrier
2. Enter the modulation/sweep/burst setting interface and set "Mod" to "On"
