Label Standard
This menu allows you to label (reference) individual standards during the menu-driven
measurement sequence. The labels are using a character set shown
on the display that includes letters, numbers, and some symbols, and they may be up to ten
characters long. The analyzer will prompt you to connect standards using these labels, so they
should be to you, and distinct for each standard.
By convention, when sexed connector standards are labeled male (m) or female the
designation refers to the test port connector sex, not the connector sex of the standard.
Class Menu
Once a standard has been defined, it must be assigned to a standard “class.” This is a group of
from one to seven standards that is required to calibrate for a single error term. The standards
within a single class can be assigned to the locations listed in 6-6 according to their
standard reference numbers.
A class often consists of a single standard, but may be composed of more than one standard if
band-limited standards are used. For example, if there were two load standards a fixed load
for low frequencies, and a sliding load for high frequencies then that class would have two
standards.
