Performing 8 term Calibration using External PC

Other topics about Advanced Calibration

Overview

To perform 8-term error model calibration using an external PC (measuring raw measurement data using the E5061B, calculating error term using external PC and then performing correction with calculated error terms and measured raw data), the procedure described in this section must be followed. When you use this method, the measurement specification is not satisfied.

Procedure

Turning OFF the "System Correction"

In its default setting, the E5061B applies "system correction" to the measured S-Parameter data. As the "system correction" is applied only to the S-Parameter measurement data and not to the absolute value measurement data, it interferes with 8-term error model calibration when calculating error coefficients on the external computer. You need to turn OFF this state all the time for calibration and measurement.

The system calibration can be turned OFF by:

The setting of system correction is kept until preset. This state is saved in the state file. This function is available at the firmware A.2.05 and above.
