Multi-tone Signal Generation

Multi-tone generation is important in a number of applications. With sufficient bandwidth and power, a generator can operate as a comb signal generator. Certain device characterization and basic immunity or interference tests may utilize function. This application strongly benefits from wider IQ bandwidth. Due to this, the SSG6082A-V has a distinct advantage in creating multi-tone signals:

The instrument menu allows the user to set the number of tones and tone spacing. Tones can be single sided or grouped around the center frequency: 

Tones all appear simultaneously and continuously across the signal bandwidth:

This type of multi-tone signal is useful for receiver
linearity testing, intermodulation distortion, and blocking characterization. This is also commonly used to test the intermodulation products of an amplifier. When multiple channels of more complex signals are called for, we recommend the article on multi-carrier signal generation.
