8.4.2 Impedance Adapter
The impedance adapter measurement mode is especially designed for measurements with the
OMICRON Lab impedance test fixtures B-WIC and B-SMC. The impedance adapter measurement
mode ensures that Bode 100 is configured correctly to achieve best results when measuring with both
B-WIC and B-SMC.
Calibration
The impedance adapter measurement mode requires impedance (open, short, load) calibration.
For more details on how to calibrate the B-WIC or B-SMC impedance adapter, please refer to
10.3.3 Calibrating an Impedance Adapter measurement on page 98.
Measurement information
With B-WIC and B-SMC, the dynamic range of both input channels is used. This widens the usable
impedance measurement range to 20 mΩ to 600 kΩ.
It is recommended to use the 0.5 m BNC cables delivered with Bode 100 to connect B-WIC or B-SMC
to the Bode 100.
B-WIC and B-SMC are designed to measure physically small DUTs. Stray-fields between the DUT and
the grounded housing of the impedance adapters might introduce a systematic measurement error.
The error is negligible when measuring physically small objects. To measure physically big DUTs it is
recommended to use a grounded measurement configuration such as shown in 8.2.1 One-Port on
page 52.
Typical applications
Typical applications for the impedance adapter measurement mode are:
• Measuring impedance of capacitors, inductors and other passives (THT and SMC).
• Measuring impedance piezo-elements or quartz elements.
