2. Use the d and e cursor keys to move the trace pointer along the graph to the location
you want.
• The coordinate values change in accordance with the trace pointer movement.
• You can exit the trace pointer at any time by pressing i.
To obtain the periodic frequency value

1. Use the procedure under "To use trace" above to start a trace operation.
2. Move the trace pointer to the start point of the range whose periodic frequency you want
to obtain, and then press w.
3. Move the trace pointer to the end point of the range whose periodic frequency you want
to obtain.
• This causes the period and periodic frequency value at the start point you selected in
step 5 to appear along the bottom of the screen.
4. Press w to assign the period and periodic frequency values to Alpha-Memory variables.
• This displays a dialog box for specifying variable names for [Period] and [Frequency]
values.
• The initial default variable name settings are "S" for the period and "H" for the periodic
frequency. To change to another variable name, use the up and down cursor keys to
move the highlighting to the item you want to change, and then press the applicable
