In this part of the tutorial lesson, you will build and test an FMCW system with a sawtooth chirp modulation. [[RF.Spice A/D]] provides three types of chirp generator devices. All three are based on sawtooth modulation but each provides a different output waveform. They are sinusoidal chirp generator, triangular wave chirp generator and square wave chirp generator. For this project, you will use the first type, which can be access from '''Menu > Parts > Waveform Generation Blocks > Chirp Generators > Sine Wave Chirp Generator'''. Set the '''Chirp Period''' to 100μs (i.e. a 10kHz chirp), and set the values of the two [[parameters]] '''freq_low''' and '''freq_high''' to 1GHz and 1.01GHz, respectively.
