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.
• Measurements using
the Keysight
16048A/B/C/D/E or
Keysight 16334A
OPEN Correction Compensate stray admittance
due to the test fixture.
• High-impedance
measurements
SHORT Correction Compensate residual
impedance due to the test
fixture.
• Low-impedance
measurements
OPEN/SHORT
Correction
Compensate the stray
admittance and residual
impedance due to the test
fixture.
• Precise measurements
OPEN/SHORT/LOAD
Correction
Compensate any error due to
the test fixture and test leads
by using the standard.
• Measurements to be
referenced to a
standard
• Measurements using a
test fixture that has
complicated
impedance
characteristics
