High-frequency low-distortion one-tone and two-tone signal generation using arbitrary waveform generator

This paper describes algorithms and simulation verification of low-distortion sinusoidal signal generation methods with harmonics and image cancellation using an arbitrary waveform generator. We show high-frequency sinusoidal signal generation algorithms with HD3 image cancellation, HD3 & HD5 images cancellation, and point out that even harmonics images (such as HD2 image) is not required because they are far from the signal frequency. Also we show high-frequency two-tone signal generation with IMD3 suppression. With these methods, distortion components close to the signal are suppressed simply by changing the DSP program-AWG nonlinearity identification is not required-and spurious components, generated far from the signal band, are relatively easy to remove using an analog filter.
