I'm trying to understand the parameters of the chirp generation on AD9914, mainly the rising and falling steps and rate. Am I correct if for example on the evaluation software the boxes for rising step and rising rate are used to generate a say 10ms chirp, and the falling step and rate are zero (or near to zero) then the generated chirp is a typical sawtooth chirp, figure a, below. If the falling steps and rates are then used, the chirp is a triangular shape?
If triangular chirp is generated, is there anyway to implement a short constant frequency between the rising and falling frequencies? (figure c below)
The other question I have is, are there guidelines or any analysis on what the steps and rate should be for a given bandwidth?
