To capture a short-duration event in greater detail, which of the following settings should you adjust?

Adjusting the frequency range, represented by Fmax, allows the analysis system to focus on capturing high-frequency components of short-duration events more effectively. In vibration analysis, events that occur over short periods of time, such as impacts or transient vibrations, often contain a wide range of frequencies. Increasing the Fmax value allows the data acquisition system to capture these higher frequencies that are significant during short events.

By expanding the frequency range, you enable the system to record more detail about the fast-changing aspects of the signal. This can lead to better identification and analysis of transient behaviors, which are crucial for diagnosing equipment health and performance.

While factors like settling time, lines of resolution, and the number of averages might influence the quality of the data to some extent, they do not specifically address the need to clearly capture the high-frequency content associated with brief events. Adjusting the frequency range is the most direct method to ensure that short-duration dynamic phenomena are well represented in the recorded data.
