number of skipped spectra, but it also reduces the total range of spectra shown. The plot
may remove spectra at the beginning or the end of the plot, and a section of total cascade
data display. Use the Page or Scroll keys to change the displayed section of the total
cascade.
A red arrow on the right side of the cascade plot indicates the current selected spectrum.
The bottom of the plot displays the time relative to the start of the cascade and the speed
measured when you collected the selected spectrum. If a single spectrum plot for the
cascade is active, the selected spectrum is shown on that plot. The single spectrum plot
changes if the selected plot in the cascade is changed.
Note
For the Center Spectrum option, the analyzer tries to center the cascade plot on the currently selected
spectrum. The plot may not center completely if the selected plot is near the beginning or end of the
cascade.

6.9.6 Collect Peak and Phase data
Peak and Phase collects and displays synchronous peak and phase waveform measurements
as a function of the equipment RPM. Use this to display data collected during start up or
coast down. A once-per-revolution tachometer pulse in addition to the vibration signal is
required.
