The time and frequency domain plots of the FM waveform output are as follows:
Frequency measurements were taken on the modulated signal and the frequency versus time
(Tracking diagram) was plotted as follows, reflecting the frequency versus modulating shape
characteristics of the modulated waveform.
Application example: Generate an AM waveform with an external source and
the following parameters
Carrier waveform = Sine, frequency = 20 kHz
Modulating waveform = Sine, frequency = 1 kHz, modulation depth = 50%
1. Set "Waveform" of the carrier to Sine and "Frequency" to 20 kHz in the parameter
setting page of the carrier.
2. Enter the modulation/sweep/burst setting interface and set "Mod" to "On"
3. Set "Type" to "AM"
4. Set "Source" to "External", set the waveform of the external modulation input to Sine
and frequency to 1 kHz, and consult the data sheet for the external input amplitude of
±5V pk-pk, which corresponds to 100% modulation. The amplitude of the external
modulation signal is therefore set to ±2.5 V pk-pk, which gives a modulation depth of
50%. The external modulation signal can be provided by another source or by
another channel of the unit.
5. Open the output
