The Tektronix VX4237 is a VXIbus C-size Digital Multimeter module engineered for integration into VXbus-based modular instrumentation systems. It operates as a GPIB interface module, enabling communication and control of IEEE 488.1/488.2-compliant instruments within the VXbus environment. The module employs message-based A16 addressing and incorporates Built-In Test Equipment (BITE) with automatic self-tests at power-up and on-command invocation. Comprehensive self-tests cover CPU, memory, and DMM circuitry with visual status indication via front panel LEDs.

– Typical Applications
Automation of test and measurement applications within modular VXIbus systems; integration of GPIB-controlled instruments into mainframe-based test environments.
– Compatibility & Integration
Fully compatible with VXIbus mainframes. When installed in D-size mainframes, consult the mainframe operating manual. When installed in Tektronix mainframes, cooling requirements are satisfied. If inserted in a slot with empty slots to the left, VME daisy-chain jumpers must be installed on the backplane.
