Background and related information
●
Refer to Chapter 4.5, "Calibration", on page 186 for background information
●
For the description of the source flatness and source power cal steps, see the
description of the Power Cal wizard.
●
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 Calibration Manager dialog.
●
The active system error correction data can be read (and modified) using the
remote control command [SENSe<Ch>:]CORRection:CDATa.
If external switch matrices are involved, use [SENSe<Ch>:]CORRection:
SMATrix:CDATa instead.
Manual calibrations
If you want to perform a manual calibration, 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.
During the calibration data acquisition phase, the lower part of the screen displays the
operation keys (or visualizations of the current actions, if the calibration is performed
via remote control).

Calibration sweep diagrams
During the calibration, the upper part of the screen displays the calibration sweep dia-
grams (magnitude and phase), each with a live and a memory trace.
●
The live traces present a live measurement of the port or port connection selected
in the lower part of the screen. They allow you to monitor the response when con-
necting a calibration standard. The traces are switched automatically when a cali-
bration sweep is performed for a different port or port connection.
●
The memory traces represent the data acquired during the previous calibration
sweep. They are updated every time a calibration sweep is completed. If no cali-
bration sweep has been performed yet, no memory traces are shown.
In the example below, the memory traces display the previously measured
response of a one-port standard connected to port 1.
Both live and memory traces represent raw S-parameters, i.e. the corresponding wave
ratio without wave correction.
