Ref Level
Specifies the reference level value, the maximum expected value to be
measure, at the reference level position. The Y-scale units depend on the
type of measurement.
• DGD and GD measurements are specified in ps.
• Gain/Loss and PDL measurements are specified in dB.
• CD measurements are specified in ps/nm.
Units/Division
Specifies the units per division of the vertical scale. The Y-scale units
depend on the type of measurement.
• DGD and GD measurements are specified in ps.
• Gain/Loss and PDL measurements are specified in dB.
• CD measurements are specified in ps/nm.
Ref. Level Position
Determines the position of the reference level on the display graticule.
View Full Range
Ensures that the highest and lowest Y-value is visible on the trace.
Snap Enabled
When selected, the mouse pan and zoom functions are snapped to a
rounded value of amplitude units. This is useful when you want to keep the
units in an easy to calculate form. Clear Snap Enable when you need
precision tuning of a portion of the graph where the exact units are
important.
Centers the graph around the response. This function is useful after using
the zoom functions.
Selected Trace
Performs an auto scale for the selected trace on the selected graph only.
Selected Graph
Performs an auto scale for the selected graph only.
