The Tektronix VX4234 is a VXIbus digital multimeter module engineered for seamless integration into VXIbus-based test systems. This C-size, single-slot module delivers 4.5-digit resolution using a guarded, dual-slope, integrating measurement technique to acquire data at rates up to 15 readings per second.

– Key Features
The guarded, dual-slope architecture minimizes errors from common-mode interference and drift, critical for precision measurement in automated test environments. High-speed acquisition at 15 readings per second supports dynamic measurement sequences without sacrificing accuracy. Dual resistance measurement modes—2-wire and 4-wire—accommodate both standard and high-precision applications. True RMS AC voltage and current measurement enable accurate characterization of non-sinusoidal waveforms.
– Typical Applications
The VX4234 suits automated test systems requiring synchronized, multi-channel measurement across voltage, current, and resistance domains. Its slot efficiency makes it ideal for space-constrained VXIbus mainframes where density and performance matter.
– Compatibility & Integration
The module integrates directly into VXIbus mainframes via the VXIbus backplane, drawing power and communication from the same interface. Compatible with standard VXIbus mainframes including the Tektronix VX1400 C-size chassis. System operation requires a VXIbus system controller; PC-based solutions using GPIB interface cards with NI-488.2M software are supported.
