Which setting should be adjusted to measure higher frequencies in the spectrum?

To measure higher frequencies in a spectrum, adjusting the Fmax setting is critical. Fmax stands for the maximum frequency limit that the analysis tool or sensor can measure. By increasing Fmax, the system can capture and analyze higher frequency ranges within the signal being monitored. This enhancement allows for more detailed assessments of vibrations and other phenomena that occur at elevated frequencies.

When considering other settings, resolution, lines of resolution, and sampling rate play significant roles as well, but they do not specifically target frequency measurement in the same way as Fmax. Resolution typically refers to the ability to distinguish between closely spaced frequency components; while lines of resolution relate to the number of frequency components presented in the analysis. Sampling rate determines how often the signal is sampled over time, impacting the ability to accurately capture fast signals, but increasing the maximum frequency limit directly enables access to higher frequencies for analysis. Therefore, adjusting Fmax is the most direct approach for measuring higher frequencies in vibration analysis.
