button in the
Basic

wizard. The wizard can be divided into 3 steps,
which guide you to finish the Deskew and Loss Compensation calibration.
At the first step, a Deskew calibration is required. The method is the same as the
operation introduced in the section "Deskew".
At the second step, the calibration operation depends on the correct DUT topology.
Under the topology Single-Ended 1 Port, you need to connect the cables and fixtures to the
VNA, connect the other ends of the fixtures to nothing or an OPEN calibration element. Click
the
Measure
button in the wizard, wait for the
mark to appear at the
Measure

finish the second step of calibration. Under other DUT topologies, you need to connect two
cables and fixtures, which are connected to the ports as the wizard instructs, to both ends of
a THRU calibration kit. Click the
Measure
button in the wizard, wait for the
mark to
appear at the
Measure
button, then execute the next operation. If under Single-Ended 4-Port
or Differential 2-Port, you will need to execute the operation as stated above once for each
page of the wizard respectively to finish the second step.
At the third step, you can connect the LOAD calibration element to every port, and click
the corresponding
Port
button to execute the calibration step. The step is optional, so it's not
necessary to finish the calibration wizard.
If you finish all necessary calibration operations, click the
