This topic describes the Triangular FM Frequency Modulation metrics displayed in the Result Tables, Histograms, and Trend Lines.
The Best-Fit metrics for Triangular FM are identical in description to those for Linear FM. For details about the Best-Fit FM metrics, see Linear FM Metrics. Note that Triangular FM has two identical Best-Fit metrics, one for the first chirp, and a "2nd" for the second chirp.
- Best-fit Apex Frequency -- describes Frequency location of the Triangular FM peak, derived from crossover point of the two individual LFM chirp’s Best-Fit reference lines.
- Best-fit Apex Time (offset relative to pulse center) -- describes Time location (reported relative to Pulse Top center time), of the Triangular FM peak, derived from crossover point of the two individual LFM chirp’s Best-Fit reference lines
