KIT DONE (MODIFIED)
terminates the cal kit modication process , after all standards
are dened and all classes are specied. Be sure to save the kit
with the

SAVE USER KIT softkey , if it is to be used later .

LABEL CLASS
leads to the label class menu, to give the class a meaningful
label for future reference during calibration.

LABEL CLASS DONE
nishes the label class function and returns to the modify cal
kit menu.

LABEL KIT leads to a menu for constructing a label for the user-modied
cal kit. If a label is supplied, it will appear as one of the ve
softkey choices in the select cal kit menu. The approach is
similar to dening a display title , except that the kit label is
limited to ten characters .

LABEL STD The function is similar to dening a display title , except that
the label is limited to ten characters .

EDIT LIMIT LINE softkey described below . If limits have
been dened 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 sucient space .
NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN
LIMIT MENU
leads to a series of menus used to dene limits or specications
with which to compare a test device . Refer to Limit Lines and
Limit T esting.
NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN
LIMIT TEST on OFF
turns limit testing on or o. When limit testing is on, the data
is compared with the dened 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 rst 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 rst value in a complex pair . The message \NO LIMIT
