Y Scale

Auto Scale

120
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 or ps/nm-km.
• PCD is specified in ps/nm.
• Depolarization Rate is specified in ps.
• 2nd order PMD is specified in ps
• Optical phase is specified in radians
Units/Division
Specifies the units per division of the vertical scale.
Ref. Level Position
Sets the position of the reference level to the chosen scale line
on the graph, where 0 is the bottom and 10 is the top line.
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 settings are important.
Centers the graph around the response. This function is useful
after using the zoom functions.
