Like noise, it is sometimes useful to play a chirp signal against a receiver. One of the gnuradio tutorials does this in a clean way using a probe. The probe follows a triangle wave level and modifies a sine wave's frequency with that value. As a learning exercise, I wanted to incorporate custom code in gnuradio.

Otherwise, there is a significant difference in the frequency of the two peaks, depending on the time offset between the chirp and the demodulation ...
