Timing Analysis Navigation Bar

The Navigation Bar spans the entire duration of the capture session from the beginning of the first packet or logic signal to the end of the last packet or logic signal. Within the Navigation Bar viewport appears that represents the visible Timeline View . The viewport is a moveable and resizable slider.

• The viewport, which is discussed in the sections below.

• Timing cursor markers placed in the timeline using the Timing button in the Navigation Toolbar. See Timing Analysis Navigation Toolbar. When a measurement is set, the Navigation Bar will display at each location of a timing cursor.

Moving the Viewport

By moving the viewport along the Navigation Bar, you horizontally scroll the Timeline View. There are four methods for moving the viewport.

1. Click on the Scroll left or right buttons on the Navigation Bar to move the viewport. The viewport will jump left or right respectively.

2. Position the cursor inside the viewport and the cursor will change to a hand. Hold down the left mouse button and drag the viewport along the Navigation Bar.

3. Left click the mouse with the cursor outside the viewport but inside the Navigation Bar. The viewport center will jump to the cursor location.

4. Use mouse while cursor is in the Navigation Bar.

Expanding or Collapsing the Viewport

Expanding or collapsing the viewport has the effect of zooming the Timeline View out or in, respectively.

• Position the mouse cursor over either the viewport's left or right edge and the cursor will change to a double-headed arrow (↔). Hold down the left mouse button and drag the viewport edge to collapse or expand the viewport thereby zooming the Timeline View in or out respectively.

You can anchor the viewport to the beginning or end of the timeline.

• Position the mouse cursor inside the viewport and the cursor will change to a hand. Holding down the left mouse button, drag the viewport along the Navigation Bar to the left edge, which is time zero. Position the cursor on the viewport right edge and drag to expand or collapse the viewport.

• Position the mouse cursor inside the viewport and the cursor will change to a hand. Holding down the left mouse button, drag the viewport along the Navigation Bar to the right edge, which is the maximum time. Position the cursor on the viewport left edge and drag to expand or collapse the viewport.

Dragging the viewport edges has the same effect as using the Timing Analysis zooming tools. When you use the zooming tools, the viewport will expand when zooming out or collapse when zooming in. See Timing Analysis Navigation Toolbar.
