The Chirp Signal block generates a sine wave whose frequency increases at a linear rate with time. You can use this block for spectral analysis of nonlinear systems. The block generates a scalar or vector output. The parameters, Initial frequency, Target time, and Frequency at target time , determine the block's output.
