Using the keyboard, press the Tab key repeatedly until the required analysis cursor begins to flash
indicating it is selected. Press the Left or Right Arrow key to move the cursor one position in
either direction. To move the cursor in increments of ten, hold the Ctrl key while pressing the
Left or Right Arrow key. The analysis cursor jumps ten positions with each key press.
(2) Analysis Pointers
The analysis pointers indicate Event time, waveform amplitude, and the absolute difference in
waveform amplitudes between the two points presently indicated by the analysis cursors.
The analysis pointers appear on both the left and right analysis cursors. On the left cursor, the top
pointer indicates the time for the current position of the cursor. The pointers inside each waveform
window display the amplitude of the waveform at the analysis cursors current position.
For the right analysis cursor, the top pointer indicates the time for the current position of the
analysis cursor. The pointers inside each waveform window indicate the amplitude of the
waveform at the cursors current position. The pointers also indicate the difference in amplitude
between the amplitude at the first cursors position and the amplitude at the second cursors
position.
The data displayed by the Analysis Pointers can be configured using the Cursor command, located
in the View menu.
(3) Calculations
Time and frequency calculations appear above the waveform windows. The time, indicated by dx,
is the time period between the two analysis cursors. The frequency calculations indicate the
frequency of the waveform located between the two analysis cursors. Frequency calculations
include full, half, and quarter calculations depending on the portion of a waveform being analyzed.
b. Timelines
The timelines indicate the timing of sequences throughout an Event. The timelines indicate delays
according to the manufacturer’s specifications. By overlaying the timelines on the Events
waveforms, it is possible to compare stated performance to actual performance.
To view timelines, click on the View Menu and choose Timelines. You have to configure your
timelines before they can appear on the Events waveforms.
To aid in analysis, the timelines can be moved as a group. To move the timelines, position the
mouse pointer over any timeline and double click the left mouse button. The analysis cursor
moves directly over top of the timeline. Press the right mouse button to select the timelines. The
selected timeline reappears as a dashed line indicating it is selected. To move the timelines,
position the mouse pointer on a timeline and click the left mouse button. Drag the timeline to the
required position. You can also use the keyboard, press the Left or Right Arrow keys to move the
timelines one position. Hold down the Ctrl key while pressing the Left or Right Arrow keys to
move the timelines ten positions with each key press.
6.2.2 Waveform Scale Control
Waveform Scale Control changes the scale of the waveform displayed in the waveform window.
The waveforms channel name along with the units of measurement appears above the window.
Within the scale window itself, a large shaded section reflects the current view of the waveform
window. To change the current view, position the mouse pointer on the waveform and double
click the left mouse button. The center of the shaded area jumps to the new position. Notice the
waveform window redisplays the waveform at this new position.
To increase the scale (enlarge) or decrease the scale (shrink) the displayed waveform, click the top
button repeatedly or the bottom button repeatedly until the desired view appears. Notice this
changes the amplitude scale located on the left hand side of the waveform window.
6.2.3 Time Scale Control
This changes the time axis scale for all displayed waveforms.
