When using a '''pre-computed waterfall''' (.res), the STFT windows are fixed in time. At sweep rates above ~50 RPM/s and for orders higher than 5×, some amplitude underestimation and peak broadening may occur. For resonance location (critical speed identification), this is generally acceptable. For amplitude-critical measurements (API acceptance tests, ISO compliance), prefer raw signals with a tacho. | When using a '''pre-computed waterfall''' (.res), the STFT windows are fixed in time.
