2005110111-3Graph Analysis Tool Graph Screen Operationsk Using TraceTrace displays a crosshair pointer on the displayed graph along with the coordinates of thecurrent cursor position. You can use the cursor keys to move the pointer along the graph.You can also use trace to obtain the periodic frequency value for a particular range, andassign the range (time) and periodic frequency values in separate Alpha-Memory values.uuuuu To use trace1. On the graph screen, press !1(TRCE).• This causes a trace pointer to appear on the graph. The coordinates of the current tracepointer location are also shown on the display.2. Use the d and e cursor keys to move the trace pointer along the graph to the locationyou want.• The coordinate values change in accordance with the trace pointer movement.• You can exit the trace pointer at any time by pressing J.uuuuu To obtain the periodic frequency value1. 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 wantto obtain, and then press w.3. Move the trace pointer to the end point of the range whose periodic frequency you wantto obtain.• This causes the period and periodic frequency value at the start point you selected instep 2 to appear along the bottom of the screen.20070101
