| The Sweep block generates a sinewave that sweeps from a start frequency to an end frequency. The sweep rate is determined by the number of sweep steps and cycles per step. In case of the linear sweep, the frequency sweep is linear across time whereas in the case of log sweep input, the frequency sweeps logarithmically cross time. The following variants of the module are available: | The Sweep block generates a sinewave that sweeps from a start frequency to an end frequency.
