Displaying the Bode Plot
When you are done setting up the Bode plot parameters, you can process the data
and display the Bode plot by pressing F4 (Display) on the RUCD - Bode Setup
screen.
The top of the display shows magnitude versus RPM. The bottom of the display
shows phase versus RPM.
To sequence through the traces, press the UP and DOWN ARROW keys. The
order number of the current trace is displayed in the top left corner of the screen.
To move the cursor along the trace, press the LEFT and RIGHT ARROW keys.
From the Bode plot you can also display the data in a Table format or Nyquist
plot. To display the data in a table, press the 0 (Shift) key and F4 (Table)
simultaneously.
