Calibrating An Impedance Adapter Measurement - Omicron Lab Bode 100 User Manual

8.3.3 Calibrating an Impedance Adapter measurement

In this section you learn how to calibrate an Impedance, Reflection or Admittance measurement in the
Impedance Adapter measurement mode.
In the External Coupler measurement mode and the External Bridge impedance measurement
mode both receivers are connected to the input Channel 1 and Channel 2 at the front panel of
Bode 100.
The Impedance Adapter measurement mode is designed for component impedance measurements
performed with the B-WIC and B-SMC impedance test-fixtures from OMICRON Lab.
B-WIC and B-SMC contain a resistive measurement bridge, which is specifically optimized for
Bode 100.
The Impedance Adapter measurement mode requires impedance calibration. You cannot
start a measurement without having Open, Short and Load calibration performed.
Figure 8-6: Calibrating the B-WIC impedance test fixture by performing Open, Short and Load
Calibration
The following pictures show how to perform Open, Short and Load calibration steps for the B-WIC and
B-SMC impedance test fixtures. Note that in the Impedance Adapter measurement mode the default
value for Load Resistor is 100 Ω and the default value for Short Delay Time is 0 ps.
