Tektronix VX4234

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.

– Technical Specifications

Module Configuration
• Form factor: C-size, 1-slot VXI module
• Resolution: 4.5 digits
• Measurement rate: 15 readings/second maximum
• Measurement technique: Guarded, dual-slope, integrating

Measurement Capabilities

• Resistance (2-wire and 4-wire configurations)
• Current DC
• Current AC (RMS and True RMS)

– 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.
