Dual waveform

Dual waveform allows you to generate a composite waveform that is the summation of two 
independent sine waveforms. Dual sine waveforms are useful in testing the intermodulation 
distortion characteristics of an audio system.

Dual waveform mode is applicable for the analog, digital, and 

Bluetooth

 generator. The 

waveform configuration for dual waveform is displayed as shown in 

Figure 3-10

, 

Figure 3-11

, and 

Figure 3-12

 for the analog, digital, and 

Bluetooth 

generator respectively.
