The TekVPI interface was introduced in 2006 (superseding the TekConnect interface) and is used in MSO/DPO2000/3000/4000/5000/7000 series scopes as well as the new 3-, 4-, 5- and 6-series MSOs.
It consists of a plain BNC connector that allows traditional BNC based connections such as from passive probes, with additional surrounding contact pads carrying power and data.
The VPI connector saw several additions/modifications with intrduction of new scopes:
- The MDO Series introduced a notch on the upper right side of the connector to key compatibility of the new 1 GHz TPP1000 probes and their 250 kΩ termination as well as the automatic probe compensation feature.
- With the introduction of the 4-, 5- and 6-series MSOs, the VPI interface was extended to include bottom row of digital logic analyzer inputs, as well as a USB interface to access the new file system that some probes like the TDP77 series now have.
Instruments and probes using TekVPI include
