If you increase the fmax (frequency range) setting, what will happen to the resolutions of the shaft in the time waveform?

Increasing the fmax setting effectively broadens the frequency range being analyzed. This means that the analysis can capture higher frequency components of the vibration data. However, when the frequency range is increased, the time waveform resolution is altered, which leads to fewer revolutions being captured in the time domain.

This phenomenon occurs because the time waveform is a representation of the vibration data over time. A higher fmax setting compresses the time intervals per revolution, thereby resulting in fewer complete cycles or revolutions being displayed within the same time duration. Essentially, with more frequency components being considered, the sampling rate must increase to accurately capture those components, which can limit the number of full revolutions captured in the resulting time series data.

Thus, fewer revolutions in the time waveform correspond to an increase in the frequency setting, highlighting how changes in frequency resolution influence the representation of data over time.
