&lt;li&gt;2xthru de-embedding attempts to remove the effect of the fixtures contacting the DUT.&lt;/li&gt;
&lt;li&gt;Although not as accurate as a SOLT calibration, it can help in situations where SOLT standards are not usable with the fixtures.&lt;/li&gt;
&lt;li&gt;To create the de-embedding parameters, a 2xThru measurement is required: Connect the fixtures of both ports directly to each other and measure their S parameters.&lt;/li&gt;
&lt;li&gt;If other impedances than 50 Ohm are used, a Fixture-DUT-Fixture measurement is also necessary, attempting to compensate the impedance. Connect the DUT between the fixtures and measure the S parameters.&lt;/li&gt;
&lt;li&gt;For more details of the 2xthru de-embedding see e.g. 
&lt;a href=&quot;https://www.signalintegrityjournal.com/articles/463-test-fixture-de-embedding-101&quot;&gt;this&lt;/a&gt; article.
&lt;/li&gt;
&lt;li&gt;For more details and examples on how to use 2xthru de-embedding in this application, see the user manual. &lt;/li&gt;
