Measurement Procedure and Examples
Correction Functions

Performing OPEN Correction
To perform an OPEN correction data measurement, set up an OPEN condition
where nothing is connected to the test fixture. While the OPEN measurement is
being performed, don’t touch the test fixture or move your hands near it.
Performing SHORT Correction
To perform a SHORT correction data measurement, set up a SHORT condition
by using a shorting bar to short between the high terminal and low terminal of
the UNKNOWN terminals.
Figure 7-16 shows a sample shorting bar for the Keysight 16047E test fixture.
The shorting bar should have very low residual impedance, so be sure to use a
high-conductivity metal plate that does not easily corrode for the shorting
plate. Furthermore, it must be clean.

Performing LOAD Correction
To perform LOAD correction data measurement, connect the LOAD standard to
the measurement contacts.
In the OPEN condition, Hp and Hc, and Lp and Lc are connected. For the
OPEN condition of the fixture, refer to the fixture’s manual.
