2.1 Disclaimer
If the equipment is used in a manner not specified by the manufacturer, the protection provided by the
equipment may be impaired. Opening the device invalidates all warranty claims. Before operating the
B ‑ WIC and B ‑ SMC, read the safety instructions in this document carefully. If you do not understand
some safety rules, contact OMICRON Lab before proceeding.
2.2 Safety Instructions
►The B ‑ WIC and B ‑ SMC are SELV (Safety Extra Low Voltage according to IEC 60950) devices, also
known as protection class III equipment.
►Only use the B ‑ WIC and B ‑ SMC in conjunction with the Bode 100. Do not apply any external
voltages or currents.
2.3 Designated Use
B ‑ WIC and B ‑ SMC have been especially designed to measure the impedance of passive components in
conjunction with the Bode 100 in laboratory or manufacturing environments.
2.4 Operator Qualification
Testing with B ‑ WIC and B ‑ SMC must only be carried out by qualified, skilled and authorized personnel.
Personnel receiving training, instructions, directions, or education on B ‑ WIC and B ‑ SMC must be under
constant supervision of an experienced operator while working with the equipment. Testing with B ‑ WIC
and B ‑ SMC must comply with the internal safety instructions as well as additional relevant documents.
2.5 Cleaning
To clean the B ‑ WIC and B ‑ SMC, use a cloth dampened with isopropanol alcohol. Prior to cleaning, always
ensure that all connections to the B ‑ WIC and B ‑ SMCand DUT
1
are disconnected.

Application Information
4 Application Information
The B ‑ WIC and B ‑ SMC test fixtures are designed to measure the impedance of passive components in
the frequency range from 1 Hz to 50 MHz in conjunction with the Bode 100 vector network analyzer.
4.1 Measurement Principle
B ‑ WIC and B ‑ SMC contain a resistive measurement bridge with a voltage divider and a current shunt.
The measurement principle is a relative voltage / current method where CH1 receives a voltage signal
proportional to the voltage at the DUT and CH2 receives a voltage signal proportional to the current
flowing thru the DUT.
Figure 4-1: Measurement principle of B ‑ WIC and B ‑ SMC
Open / Short / Load calibration must be carried out to compensate for parasitic effects and non-ideal
behavior occurring at higher frequencies. To learn how to calibrate the B ‑ WIC and B ‑ SMC, please refer
to 4.4 Calibration / Correction on page 8.
4.2 Device Connection
The figure below shows the connection from Bode 100 to B ‑ WIC and B ‑ SMC. It is recommended to use
the 0.5 m long BNC cables delivered with the Bode 100 for the connection.

B-WIC & B-SMC User Manual
4.3 Software Settings & Configuration
When measuring with B ‑ WIC and B ‑ SMC make sure to use the Impedance Adapter measurement
mode in the Bode Analyzer Suite as shown below:
Note, that you must perform an impedance calibration / correction before you can start measuring.
Check out the next chapter to learn how to perform the Open / Short / Load calibration.
After the calibration has been performed, you can start either a single
sweep or a continuous sweep by clicking on the corresponding icons.
4.4 Calibration / Correction
Before you can start a measurement, Open / Short / Load calibration / correction must be performed.
This moves the reference plane from the Bode 100 front panel to the DUT connection points of the
B ‑ WIC and B ‑ SMC as shown below:
Figure 4-3: Reference plane after Open / Short / Load calibration
To start a calibration, select either the User-Range Impedance Calibration or the Full-Range Impedance
calibration by clicking on the corresponding icon.
To learn about the difference between Full-Range and User-Range calibration, please refer to the
Bode 100 User Manual.

Application Information
4.4.1 Calibrating B-WIC using B-CAL board
Open
Short
Load
Place no DUT to the
electrodes and start the
Open calibration.
Place the B-CAL board
with the Short-side into
the B-WIC electrodes and
start the Short calibration.
Place the B-CAL board
with the Load-side into
the B-WIC electrodes and
start the Load calibration.
4.4.2 Calibrating B-SMC with a 100 Ω resistor
Open
Short
Load
Use the knurled nut to
adjust the distance of the
electrode needle to the
plate to match the DUT
size to compensate for
stray-capacitance and
start the Open calibration.
Loosen the knurled nut
until the needle touches
the electrode and start
the Short calibration.
Place a 100 Ω resistor
between needle and
electrode and start the
Load calibration. For best
accuracy, use a precision
thin-film 100 Ω resistor
with low temperature
coefficient as included in
the delivery of B-SMC.

4.5 Connecting the DUT
Please follow the rules outlined in this section to ensure best measurement accuracy using B ‑ WIC and
B ‑ SMC
4.5.1 Avoid Leads and Large DUTs
Do not use extra leads to connect the DUT to the B ‑ WIC and B ‑ SMC test fixtures. Extra leads will
introduce stray capacitance to ground / housing. This can cause currents to bypass the internal
measurement bridge, causing errors in the measurement. The same is true for physically large DUTs.
Figure 4-4: Stray capacitance of leads and physically large DUTs
4.5.2 Electrode Dimensions
The following pictures show the geometry of the B ‑ WIC and B ‑ SMC electrodes.
Maximum DUT wire diameter is 1.8 mm.
Minimum spacing of DUT wires (clearance) is
3 mm. The electrode length is 24 mm.
Maximum DUT size that can be placed in the
B-SMC is of 9.5 mm length and 7.5 mm width.
Note that the needle electrode is in the center.
