Overview
The E5071C has the following calibration coefficients for full N-port
calibration: Er, Es, Ed (reflection), Et (transmission), and Ex (isolation).The
partial overwrite function is used to measure some of these calibration
coefficients after completion of the initial calibration and then to overwrite
them.
The conditions under which the calibration coefficients can be calculated by
the partial overwrite are as follows:
Calibration is completed once and valid (status other than C? or C!)
•
One or more measurements for re-calculation are performed.
•
The isolation calibration coefficient, Ex, cannot be returned to
•
the initial value, 0, once it is calculated.
If calculation of the calibration coefficients is attempted without the
measurements required to execute the partial overwrite, an error message
(20: Additional Standard Needed) is displayed.
Executing calculation of calibration coefficients using partial overwrite
To calculate the calibration coefficients using partial overwrite, use the
following command:
:SENS{1-36}:CORR:COLL:PART:SAVE
Before you can calculate the calibration coefficients with the
•
partial overwrite, you must select the appropriate calibration
type in the same way used for normal calibration. If calculation
of the calibration coefficients is attempted without selecting the
calibration type, an error message (28: Invalid Calibration
Method) is displayed.
