Key Features
Overview
The B-TCA Test Card Adapter by Omicron-LAB is a precision-engineered fixture designed for impedance and S-parameter measurements of surface-mount devices (SMDs) across a wide frequency range up to 450 MHz. Ideal for electronic design engineers, this adapter simplifies testing passive components such as capacitors, inductors, and resistors using One-Port, Shunt-Thru, or Series-Thru configurations, ensuring accurate characterisation of complex impedance.
Compatible with vector network analysers like the Bode 100 and Bode-500, the B-TCA includes N-type and PCIe edge-card connectors for seamless integration into test setups. Its modular design requires soldering components to dedicated test cards, enabling repeatable measurements with minimal contact resistance. The adapter is supplied with calibration standards and eight test cards per setup, ensuring rapid deployment and reliable results.
For engineers seeking efficiency, the B-TCA eliminates the need for complex fixturing, reducing setup time while maintaining laboratory-grade accuracy. Its competitive edge lies in supporting both impedance analysis and S-parameters within a single compact solution—a critical advantage for prototyping or quality assurance in high-frequency applications.

Questions and Answers
-
How Are Components Prepared for Testing with the B-TCA?
Components are soldered directly to the test cards. This gives consistent, low-resistance connections (signal contact typically 2 mΩ with under 1 mΩ repeatability) and better represents real PCB mounting.
-
What Are the Key Advantages of the B-TCA's Calibration System?
Each measurement setup has its own dedicated calibrator with Open/Short/Load references. This accounts for the characteristics of each measurement topology and enables precise error correction.
-
How Does the B-TCA's Card Exchange System Improve Workflow Efficiency?
The 100-pin card-edge connector lets you change test cards quickly without reconnecting the measurement cables. It gives a reliable mechanical and electrical connection for fast component changeover.
-
What Replacement Test Card Sets Are Available for the B-TCA?
Debug Store offers optional replacement test card sets. Each includes 32 test cards (4 sets of 8 pieces) plus one dedicated calibrator for its measurement configuration:

What Is the Omicron-Lab B-TCA Test Card Adapter and What Makes It Unique?
The B-TCA (Test Card Adapter) is a test fixture for impedance and S-parameter measurements of surface-mount components from DC to 450 MHz. What sets it apart:
- A card edge connector system for quick test card exchange
- Dedicated calibrators for each measurement setup
- Type N connectors for better connection repeatability
-
What Frequency Range Does the B-TCA Cover and How Does This Compare to Premium Competitors?
The B-TCA covers DC to 450 MHz.
-
What Types of Measurements Can Be Performed with the B-TCA?
The B-TCA supports four measurement configurations:
- One-Port impedance (S11 reflection)
- Shunt-Thru impedance
- Series-Thru impedance
- Shunt-Thru with Rs
Together the setups cover impedances from milliohms to megohms (Shunt-Thru best for 1 mΩ to 100 Ω, Series-Thru for 1 kΩ to 1 MΩ), with S-parameter analysis and characterisation of passive surface-mount components from DC to 450 MHz.
-
What Is Included in the Standard B-TCA Test Card Adapter Package?
The standard B-TCA package includes:
- Test card adapter unit
- Two N-N cables (30 cm)
- Two N-BNC cables (50 cm)
- Dedicated calibrators for each measurement setup (Shunt-Thru, Series-Thru, One-Port and Shunt-Thru with Rs)
- Eight test cards for each measurement configuration (32 test cards in total)
