All about Limit Lines

Limit Lines are available in CAT Mode and NA Mode. Power Meter Mode uses
different Limit settings. Learn more on page 67.
Limit Lines are visual representations on the FieldFox screen of the specified
limits for a measurement. With this capability, you can easily compare measured
data versus specifications. In addition, you can enable an audible beep and
display Pass or Fail information for each measurement.
You can have up to 10 Limit Lines for each measurement trace allowing you to
test all aspects of your measurements.
With multi-trace configurations, Limit Lines are applied individually for each
displayed trace. Learn more on page 21.
Limit Lines can be saved and recalled with an *.sta file. Learn more about *.sta
files on page 86. They can also be saved and recalled independently from the
Limit softkeys. Learn more on page 83.
Limit Lines and Limit testing are NOT allowed with Smith Chart or Polar display
formats.
How to Create Limit Lines
