NVH 203

4.0 NVH DISPLAYS

When using the Vibration and Noise modes, the Tester offers a variety of ways to display

real time and stored data. A brief description of each display mode is listed below. A

complete description of operating each display mode is on the following pages.

TWO-DIMENSIONAL (2-D) SPECTRAL DISPLAY MODE

Frequency bands of 62.5 hz, 125 hz, 250 hz, and 500 hz are available for viewing real time

spectral Vibration or Noise data. Vibration component identifiers for the engine, driveline,

or wheel frequencies are displayed on the screen. A moveable cursor identifies the

magnitude and frequency of the vibration that is present at the current cursor position.

THREE-DIMENSIONAL (3-D) BARCHART DISPLAY MODE

Vibration or Noise data are displayed in bars that reflect the engine, driveline, wheel, and

total energy sampled. Eleven continuous cycles are displayed for analysis. The most

recent is displayed at the bottom of the Barchart display. Frequency bands of 62.5 hz, 125

hz, 250 hz, and 500 hz are available for viewing real time spectral Vibration or Noise data.

THREE-DIMENSIONAL (3-D) RASTER DISPLAY MODE

Eleven cycles of Vibration or Noise data are displayed in a 3-D format. The most current

cycle is located at the bottom of the 3-D display. Frequency bands of 62.5 hz, 125 hz, 250

hz, and 500 hz are available for viewing real time spectral Vibration or Noise data.

Vibration component identifiers for the engine, driveline, or wheel frequencies are

displayed on the screen.

PAUSE MODE

In the PAUSE mode you may cycle through the 2-D and 3-D display modes. In the 2-D

and 3-D spectral displays, vibration component, identifiers for engine, driveline, and

wheels are available. The amplitude range is also adjustable. Data can be saved in memory

for review at a later time; stored data is retained even when the Tester is powered down.
