The multitone waveform may be configured with the following parameters.
– Start Frequency
– Amplitude
– Tones
– Multiplier
– DC Offset
– Phase Mode
Start frequency refers to the waveform fundamental frequency.
Tones refer to the number of signal frequency components.
The multiplier is used to multiply the start frequency to determine the frequency
spacing between the tones.
The phase mode consists of the Zero Phase and Random Phase mode. In the Zero
Phase mode, all frequency components have the same phase where there is zero
phase difference between any two tones. In the Random Phase mode, the phase
difference between the tones is randomized. This has the effect of reducing the
crest factor for the multitone waveform.
You may display the multitone waveform as follows.
