The following equipment is required to perform magnetic measurement.
Connect the test head to the E4991B. Be sure not to remove the four feet on the bottom of the E4991B when connecting the test head.
Do not connect the test fixtures to the test head at this point because calibration is performed on the DUT port (7-mm terminal) of the test head later.
Press the power switch to turn ON the power to the E4991B. The E4991B performs a power-on self-test. When the self-test is completed, the measurement screen appears on the LCD.
