*1. These calibration data can normally be used to measure DC resistance (Rdc). If required, a dedicated standard can
be prepared to perform a separate DC open/short/load calibration to obtain data for measuring DC resistance.
*2. Included in the "Agilent 16195B 7-mm calibration kit."
Calibration reference plane and required calibration and
compensation
Actual measurement is performed with the desired combinations of calibration and
compensation functions given in Table 6-1 on page 116. Basically, either method A or B
shown in Table 6-2 is selected, depending on the position of the calibration reference plane.

*1. Indicates the 3.5-mm terminal of the test head or one equipped with an adapter.
*2. Includes Agilent 16195B 7-mm calibration kit.
*3. Since the low-loss capacitor is designed as a 7-mm type capacitor, calibration is possible only when the calibration
reference plane uses a 7-mm connector.
*4. When you use a dedicated test fixture with a registered electrical length, you simply have to select the fixture
model number.
*5. A reference device valued at the same contour as the DUT. Option 004 (working standard set) or similar can be
used.
NOTE
No calibration or compensation other than open/short/load calibration is required when the
DUT connection terminal is used as a calibration reference plane (B in Table 6-2).

Position and method
For this calibration, connect a coaxial
*2
compensation kit
to the test head
coaxial terminal (used as a calibration
reference plane).
For this calibration, connect a low-loss
capacitor to the calibration reference
*3
plane.
Enter the electrical length data from the
calibration reference plane through to
the sample connection plane into the
*4
Agilent 4287A.
For this compensation, keep the DUT
connection terminal open or shorted
out.
For this calibration, connect a working
*5
standard
to the DUT connection
terminal (used as a calibration reference
plane).
