Linear Chirping

Linear Chirping

The DSM202 offers linear up-chirping so the step frequency will be constant for a specified chirp. The user is able to change the step frequency when the module is stopped but for a given waveform, the difference between successive frequencies will be the same when the DSM202 is running.

The graph below shows a graphical example of a 16-point linear chirp where the step frequency is 1/256 of the input clock frequency.

Graph of Linear Chirping

The following photo is an actual waveform produced by the DSM202. The input clock is 2 GHz. The module starts at 7.8125 MHz and chirps all the way up to 125 MHz in steps of 7.8125 MHz. The signal below the chirping waveform is the marker.
