In 2005, the DVT30 1st multi-mode GigaProbes® TDR Probe was used to characterize the early differential trace impedances on prototype PCBs connecting LVDS I/O digital drivers. The DVT30 was the first differential probe not needing a physical ground reference to measure differential TDR impedance.
In 2011, the DVT40 Multi-Mode TDR and VNA Probe was developed as a collaborative effort to create the first 40 GHz variable-pitch multi-mode probe. Introduced at DesignCon 2011, it was paired with the new 40 GHz 4-port VNA, delivering to engineers a low-cost 40 GHz differential PCB probing system for measuring differential S-parameters and impedances. The DVT40 introduced probe tips plated with 4-6 um of conductive diamonds for easier cutting through surface oxides.
In 2019, DVT-FFPXX High-Fidelity 40 GHz - 70 GHz differential probes were developed to probe 1.0 mm wide pitches. Typical applications include characterization of transmission lines and devices which are compliant to the industry's cutting-edge high-speed standards such as PCIe 5.0/6.0, 802.3ck, and Infiniband 104G-IB-EDR.
