finishes the label class function and returns to the modify
cal kit menu.
leads to a menu for constructing a label for the
user-modified cal kit. If a label is supplied, it will appear
as one of the five softkey choices in the select cal kit menu.
The approach is similar to defining a display title, except
that the kit label is limited to ten characters.

draws a quarter-page plot in the lower left quadrant of the
page.
draws a quarter-page plot in the upper left quadrant of the
page.
leads to the offset limits menu, which is used to offset the
complete limit set in either stimulus or amplitude value.
turns limit lines on or off. To define limits, use the
softkey described below. If limits have
been defined and limit lines are turned on, the limit lines
are displayed on the LCD for visual comparison of the
measured data in all Cartesian formats.
If limit lines are on, they are plotted with the data on a
plot, and saved in memory with an instrument state. In a
listing of values from the copy menu with limit lines on,
the upper limit and lower limit are listed together with the
pass or fail margin, as long as other listed data allows
sufficient space.
leads to a series of menus used to define limits or
specifications with which to compare a test device. Refer to
“Limit Line Operation” in the “Operating Concepts”
chapter of the user’s guide and the limit line testing
section of the “Making Measurements” chapter of the
user’s guide.
turns limit testing on or off. When limit testing is on, the
data is compared with the defined limits at each measured
point. Limit tests occur at the end of each sweep,
whenever the data is updated, when formatted data is
changed, and when limit testing is first turned on.
Limit testing is available for both magnitude and phase
values in Cartesian formats. In polar and Smith chart
formats, the value tested depends on the marker mode and
is the magnitude or the first value in a complex pair. The
message "NO LIMIT LINES DISPLAYED" is displayed in
polar and Smith chart formats if limit lines are turned on.
