Correction Functions
The E4980A/AL features powerful correction functions: Cable Length
correction as well as OPEN, SHORT, and LOAD corrections. These correction
functions are used to correct additional error due to the test fixture and the test
leads. Table 7-2 lists the correction functions with a brief description, and
Table 7-3 shows examples of using correction functions.

Correction Function Description Typical Usage
Cable Length
Correction
Compensate phase shift error
due to the 1, 2, or 4 m test
leads.
