WebChirp / (T. Chirp. x B. 2) – B represents the 3 dB IF bandwidth = RBW in Hz, which is established by rule as 1 MHz – The figure shows that measured amplitude is reduced as the normalized sweep rate increases – Information is provided in C63.26 procedures, and will be included in the forthcoming KDB guidance, to correct for this amplitude ... There is very little spectral content beyond the sweep frequency range of a chirp pulse and this is especially true for waveforms where the time-bandwidth product is large. The full line on the graph of the adjacent figure shows results for linear chirps. It shows, for example, that only about 2% of the total power resides at frequencies outside the sweep range ΔF when the time-bandwidth i…
