TRIDENT
Open Source, High Precision Spring-Loaded UHF Probe
The TRIDENT probe is a compact, high-frequency diagnostic instrument engineered for precise PCB measurements. Its mechanically robust copper chassis is directly grounded to the board, providing a low-impedance return path that sustains signal fidelity well into the multi-gigahertz spectrum. The probe's trineedle architecture ensures a stable reference plane and consistent coupling to the stripline under test.
Features:
- Compact form factor: A 44mm tall copper chassis, optimized for space-constrained test environments and fabricated from reclaimed copper sourced from electronic waste.
- Grounded copper enclosure: Chassis is soldered directly to the PCB, creating a low-impedance return path that preserves signal integrity into the multi-gigahertz range.
- Trineedle architecture: Two outer, spring-loaded ground contacts engage the board's ground pours, establishing a stable reference plane. The central needle mates precisely with the stripline under test, delivering consistent signal coupling.
- High-precision PCB fabrication: Utilizes the finest tolerances and material selections currently available to minimize parasitic inductance and maximize high-frequency performance.
- Compatibility with standard peripherals: Requires no proprietary components, enabling seamless integration with existing test equipment.
- Rapid prototyping workflow Engineers can quickly prototype, validate, and iterate high-speed designs while benefiting from the transparency and extensibility of an open-source hardware platform.
- Open-hardware licensing: Entire hardware design is released under the CERN Open Hardware Licence (CERN-OHL-S), permitting unrestricted modification, redistribution, and collaborative improvement.
