Option Description
F2 Set Spectra
Params
Set the Fmax, Fmin, and lines of resolution. See Section 6.7.1 and
Section 6.7.2.
F3 Set Cascade
Params
Set the number of spectra to collect, force an RPM measurement, and
select the sample type to set how the analyzer collects new data. The
sample type is not the same as a trigger and takes precedence over a
trigger. Select Continuous to collect data immediately, Delta Time to collect
after a specified time interval, or Delta RPM to collect after a specified
change in RPM.
For Delta Time samples, select the minimum time delay (in seconds) between
the start of each collected spectrum.
The default is 20 spectra, Force RPM is disabled, and Continuous mode is
selected.
F4 Set Window Set the type of window to use. See Section 6.7.3.
F5 Set AWeight Apply a shape curve to the acquired frequency spectrum that approximates
the frequency sensitivity of the human ear. Aweighting is used with
microphone signals when you want to see perceived “loudness.” A high
sensitivity, low frequency sensor is recommended. Use a general purpose
accelerometer, such as part number A0760GP, for measurements as low as
40 RPM. Contact customer service for recommendations to measure lower
frequencies.
F7 Tach Setup Set up the tachometer parameters. See Section 6.6.
F8 PeakVue
Demod
Enable or disable PeakVue or Demodulation. See Section 6.7.5.
F9 Set Trigger Set the type of trigger to collect data. The Level Trigger and RPM Trigger
only start collection of the very first spectrum in the series. All other spectra
are collected without a trigger. These two modes do not permit pre-
triggering. When using the Tach Trigger, a Set Tach Start option is available.
See Section 6.7.6. By default, the trigger is disabled.
F12 Input Setup Set up the input channels, the sensor type, and the units for the acquisition
type. See Section 6.5.
6. Press Enter to collect the data.
One or more plots display the data.
7.
Press F9 Store Data to save the data, or press F8 Start to redo the measurement.
Cascade plots
Collected spectra display in a waterfall graphic with a three-dimensional effect. View
cascade plots alone or in a dual plot, including a single spectrum plot of one of the spectra
in the cascade. In a dual plot, the selected spectrum on the cascade plot is shown on the
single spectrum plot.
The analyzer may automatically compress cascade plots if all the spectra in the cascade do
not fit on the plot. Some intermediate spectra may be skipped or removed from the plot,
so you can view an overview of the entire cascade. Expanding the cascade plot reduces the
