Dawn VME VME64UXB12DJ0-CS/SW VME64 Test Extender Board

The Dawn VME VME64UXB12DJ0-CS/SW is a 6U VME64x universal test extender board that extends VME64 bus signals for comprehensive in-system debugging and signal analysis. Built to ANSI/VITA 1997-1 and ANSI/VITA 1.1 standards, this board provides direct access to all J1, J0, and J2 connector pins through a 12-layer stripline PCB design. Every pin on the J1, J0, and J2 connectors is uncommitted to power or ground and bussed as signal, enabling flexible signal routing and measurement.
