All about Limit Lines
Limit lines are visual representations, drawn on the FieldFox screen, of the specified limits for a
measurement. With this capability, you can easily compare measured data versus specifications.
Optionally, you can enable an audible beep and display
Pass or Fail
information for each
measurement.
— You can have up to as many limit line segments as there are data points for each measurement
trace allowing you to test all aspects of your measurements.
— Limit lines are available in CAT Mode, NA Mode, NF Mode, and SA Mode. Power Meter Mode
uses different limit settings. Learn more in
— Limit lines and limit testing are NOT allowed in NA Mode with
Smith Chart
or
Polar
display
formats.
— A simple Display Line is also available in I/Q Analyzer, NF, and SA Modes ONLY. Learn more in
“Display Line (I/Q, NF, and SA Modes Only)” on page 465
