The Tektronix Option 01 is a VXI interface daughterboard designed to operate as a message-based VXIbus servant within VXI-based instrumentation systems. This C-size daughterboard installs directly onto Tektronix SurePath VXI switching modules to provide command and control capability via the VXI Word Serial Protocol. It accepts SCPI-compatible commands conforming to 1994 SCPI and IEEE-488.2 specifications, enabling precise control of relay matrices and scanner modules across contiguous slots.
Technical Specifications
• Protocol: VXI Word Serial Protocol servant interface
• Command Set: SCPI-compatible per 1994 SCPI and IEEE-488.2
• VME Interface: A16, D16 via VXIbus P1 connector; D16 interrupter
• Address Space: Requires A16/D16 only; no A24 or A32 needed
• Module Control Capacity: One to 12 relay modules via P2 local bus
• Form Factor: C-size daughterboard, approximately 3 inches × 9 inches
• Power: Operates within VXIbus mainframe power specifications; deactivates SYSFAIL* except upon +5 V loss on installed relay module
• Thermal Management: Cooling requirements met when installed in Tektronix mainframe; requires adequate ventilation
• ESD Sensitivity: Requires ESD precautions during handling
– Key Features
• Controls the relay module on which it is installed plus adjacent SurePath and Scanner Slave modules in contiguous right-side slots
• Message-based servant architecture—not a VXIbus commander or VMEbus master
• P2 local bus communication with adjacent modules
• No A24/A32 address space requirement reduces system complexity
– Typical Applications
• RF and analog signal routing in modular VXI test systems
• Multi-module relay and switching control within compact mainframes
• Integration with Tektronix SurePath matrix and scanner modules
– Compatibility & Integration
Compatible with Tektronix SurePath family modules: VX4320 RF Mux, VX4330 Scanner/Mux, VX4350 General Purpose Switch, and VX4380 Matrix modules. Also supports VX4372 and VX4374 Scanner Slave modules. Requires a VXIbus commander device for operation.
