Tektronix VX4234 Digital Multimeter Module

The Tektronix VX4234 is a 4.5-digit digital multimeter module engineered for VXIbus-based test and measurement systems. This C-size, 1-slot module delivers guarded, dual-slope, integrating measurement architecture with a measurement rate of 15 readings per second. It performs DC voltage, AC voltage (True RMS and RMS), 2-wire and 4-wire resistance, DC current, and AC current (RMS and True RMS) measurements. The module draws all required DC power from the VXIbus mainframe, eliminating external supply dependencies.

– Compatibility & Integration

The VX4234 integrates into C-size VXIbus mainframes, including the Tektronix VX1410A IntelliFrame. It conforms to VXIbus specification and VXIplug&play standards. VXIplug&play drivers are available, enabling straightforward integration with automated test systems and data acquisition platforms. Power distribution occurs entirely through the VXIbus backplane, streamlining system architecture.
