The nVent/Schroff 20800-186 is a VMEbus test adapter that provides direct access to test points on VMEbus boards, enabling engineers to connect test equipment such as oscilloscopes for signal analysis and functionality verification. This 3U adapter delivers simultaneous voltage and current measurement capabilities through dedicated measuring fields and probe-tip pins, supporting comprehensive signal characterization and system troubleshooting on VMEbus backplanes.
Technical Specifications
• VMEbus standard compliance with conductive track and layer build-up conforming to VMEbus requirements
• Voltage supply lines rated for 2 A
• Measuring field for voltage and current (V/I) measurements
• Additional measuring pins configured for oscilloscope probe tips
• Available in 3U rack height configuration
• 6U solutions achievable by linking two 3U adapters via intermediate adapter
– Key Features
• Direct test point access on VMEbus boards
• Dual measurement capability (voltage and current) on single adapter
• Pin positions for second test object connection
• Terminator board connection provision
• Modular design enabling scalable test solutions
• Standard DIN 41612 connector compatibility typical of VMEbus systems
– Typical Applications
The 20800-186 supports signal analysis, functionality verification, and troubleshooting of VMEbus-based systems. Engineers use this adapter during development and maintenance cycles to characterize board behavior, verify signal integrity, and diagnose system-level faults through direct oscilloscope access to critical test nodes.
– Compatibility & Integration
The adapter integrates directly into VMEbus backplane slots, facilitating connection of external test equipment to the bus structure. Multiple 3U units can be cascaded using intermediate adapters to form 6U or 9U test solutions, enabling flexible test configurations across systems of varying complexity.
