Logic Analyzer 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 resizeable slider.

Within the Navigation Bar you will see

• the viewport, which is discussed in detail below.
• Timing cursor markers placed in the timeline using the Timing button in the Tools . See "Logic Analyzer Tools ". When a measurement is set the Navigation Bar will display at each location of a timing cursor.
• Scrolling buttons at each end of the Navigation Bar. These buttons will scroll the viewport across the Navigation Bar.

Moving the viewport

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

• Click on the Scroll left or right buttons to move the viewport. The viewport will jump left or right respectively.
• Position the cursor inside the viewport ; the cursor changes to a cross (+). Hold down the left mouse button and drag the viewport along the Navigation Bar.
• Left click the mouse with the cursor outside the viewport but inside the Navigation Bar. The viewport left edge will jump to the cursor location.

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; the cursor changes 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; the cursor changes to a cross (+). 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; the cursor changes to a cross (+). 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 Logic Analyzer zooming tools. When you use the zooming tools the viewport will expand when zooming out or collapse when zooming in. See "Logic Analyzer Tools "
