Results menu Let you expand/collapse the signals in a label, set the bus
view, set the sampling positions to the suggested sampling
positions, and remove all eye finder data.
Label buttons Let you expand/collapse the signals in a label, set the bus
view, choose the suggested sampling position, and show
message or time stamp information.
Display Area Shows:
• Transitioning (dark) and stable (light) regions on the signals.
• Suggested sampling positions (green triangles).
• The current sampling positions (blue lines).
• Informational message icons . You can move the mouse pointer over the
icon to cause the message to pop up.
• Time stamp icons . You can move the mouse pointer over the icon to
see when the last eye finder measurement was run.
To give you more information about the signals, the display
covers +/-5 ns even though the sampling position may only
be set to +/-3.25 ns.
Sampling
Position Lets you adjust the sampling position. You can also drag the
sampling position bar to a new location.
