If the calibration setup for a calibrated channel is not changed and sweep data are
available from previous calibrations, the existing system error correction can be
optimized without repeating the measurement of all standards.
●
When you apply the new calibration, the current calibration is replaced and discar-
ded.
To persist the current calibration, you can transfer it to the calibration "Pool" using
the

The active system error correction data can be read (and modified) using the
remote control command
Manual calibrations
If a manual calibration shall be performed, the calibration wizard allows you to acquire
error correction data for every required port (pair) and calibration standard, where
"required" depends on the selected ports and calibration type.

Calibration Sweep Diagrams
During the calibration sweep, each diagram contains a single S-parameter trace and a
typical result trace for the measured calibration standard.
The purpose of the typical result traces "Trc1"" and "Trc2" is to avoid connection errors:
If the correct standard type is measured, and everything is properly connected, then
the measured trace is expected to be similar to the typical trace.
Power Sweep Diagrams
Power sweep traces are displayed during the "Power" calibration sweeps of a SMAR-
TerCal.
