Setting The Electrical Length Of The Test Fixture - Agilent Technologies 4286A User Manual

5. Setting the Electrical Length of the Test Fixture

In the RF region, the wavelengths are short and are not negligible compared to the physical
transmission line length of the test xture. This causes a phase shift error. The phase shift
error is compensated by the electrical length parameter for the test xture. Because the
electrical length values for the Agilent Technologies test xtures are stored in the 4286A, you
can set the electrical length parameter by selecting the xture model number.
