Displaying Measurements
by Using a Bode Plot

The Bode plot is actually two graphs of 1X rpm amplitude and phase as a
function of frequency. The screen shows both plots at the same time. The top
plot shows magnitude versus rpm. The bottom plot shows phase versus rpm.

Set Up the Bode Plot

1.

Select Bode on the RUCD - Display Select screen and press F3 (Display).

The RUCD - Bode Setup screen appears.

2.

Select the parameter and press the Right arrow to open a list of values.

3.

Select or type in the parameter value.

4.

Press the Left arrow to save your selection.

See

Bode Plot Parameters on page 23

to help you configure the parameters.

Table

Displays the magnitude and phase of selected orders at the varied rpm speeds
in a table format.

See

Displaying Measurements in Table Format on page 28

.

Waterfall

Displays multiple FFT traces overlaid and offset on one single plot.

See

Displaying Measurements Using a Waterfall on page 31

.

Spectrogram

Displays multiple FFT traces on one single plot, using color to indicate relative
magnitude.
