The Picotest Component Test Fixture is a precision, two-port shunt-through measurement interface designed specifically for ultra-precise impedance (capacitance, inductance, impedance magnitude & phase) characterization of discrete components over a wide frequency range and with the ability to DC bias components up to 75VDC. With this fixture you can connect directly to a vector-network analyzer (VNA)with minimal parasitics and outstanding accuracy and repeatability. The CTF is especially designed to work with VNAs such as the OMICRON Lab Bode 100/500 and the Keysight E5061B.
The CTF provides a highly accurate impedance-measurement solution for OMICRON Lab Bode Analyzer users, making it an essential tool for engineers designing, modeling, and validating high‑performance power distribution networks.
Pair the CTF with your Bode Analyzer today to unlock highly accurate component measurements.
Whether you are creating models for SPICE, Keysight ADS, or end-to-end PDN/impedance simulation, the fixture empowers you to base your work on real, measurement-derived impedance data rather than relying on approximate datasheet values.
Mounting is fast and intuitive—swap in inductors, capacitors, resistors or custom beads, apply AC and an optional DC bias, and capture impedance vs frequency, phase, or parasitic inductance as needed. With support for uΩ to kΩ impedance levels and DC to 3 GHz bandwidth, the fixture covers most discrete component test needs for power-electronics, aerospace, cloud/data-center and automotive power-integrity work.
The CTF includes the bottom base unit (with 2-port connectors), DC bias module, and top personality module with pin contacts. Calibration, sample, and blank DUT boards are also included.
Customized DUT boards to test under/oversized parts or updated personality modules for other devices are available.
Included in the kit are SMA and N torque wrenches for consistent connector engagement, calibration standards (SOLT boards and impedance calibration), blank DUT boards, and known reference DUTs so you can verify and optimize your setup. Built-in common-mode transformers isolate the shunt path from ground-loop artifacts—so you don’t need to add external isolators. Simply connect your VNA, apply bias if required, calibrate, mount the part and measure—delivering component data that directly feeds into your modelling, simulation and PB-networks. With the Picotest Component Test Fixture you gain:
- A compact, repeatable 2-port measurement setup optimized for discrete component impedance quantification.
- Full compatibility with VNA workflows and simulation-model creation (capacitance, inductance, ESR, impedance vs frequency, phase).
- De-embedding and calibration ready so that you minimize fixture-residual error and maximize the fidelity of the DUT measurement.
- Flexible mounting and bias capability (AC via VNA; DC bias up to 75 V) supporting realistic operating conditions.
- A comprehensive kit—including reference parts, calibration boards and blank DUT boards—so you are up and running quickly with known performance.
In short, this fixture is engineered for power-integrity and component-characterization engineers who demand measurement-based models, not just datasheet approximations. It enables the accurate benchmark data you need to ensure your simulation models reflect real-world behavior, improving your confidence in the results and integrity of your end-applications.
