Toolbar Buttons 5

Clicking the “Graph Toolbar” button will bring up a buttons toolbar, which provides a means of

quickly implementing various plot display functions. An alternative to using the buttons is to

“right-click” in a plot display, then use the resulting function menu. When the graphic toolbar

is open, clicking the button again will close it.

Function Description / Comments

1 Add New FV Window Adds a new Function View.

2 Tile Horizontally Tiles two or more Function Views such that they are longer in the

horizontal direction.

3 Tile Vertically Tiles two or more Function Views such that they are longer in the vertical

direction.

4 Time A single-channel display function. Displays a time domain waveform of

sampled data scaled in either Volts or EUs.

5 Auto-Spectrum A single-channel display function. Displays the square of the magnitude

of the complex (one-side) Fourier spectrum of x(t). Autospectra are

calibrated so that if A is the peak amplitude of a sinusoidal signal x(t),

then the autospectrum has the value A*A (or use A power 2) at the

sinusoidal frequency.

6 PSD

(Power Spectral

Density)

Power Spectral Density (PSD) displays the power of random vibration

intensity as “mean-square acceleration per frequency unit.” PSD is a

single-channel display function. It is the Fourier Transform of the Auto-

correlation function. This normalization should be used with continuous

random signals.

7 Spectrum A dual-channel display function. Displays averaged linear spectrum

computed as the square root of the averaged autospectrum.
