Ground Vibration Testing (GVT) is essential in the verification process of aircraft. Conducting GVT can be time consuming, and measurement inaccuracy and test errors can quickly become very costly. When an international aircraft manufacturer was faced with upgrading their legacy GVT system, VTI was selected to create a >500 channel count, distributable GVT System, that consisted of multiple rugged PXI Express mainframes, dynamic signal analyzers, and LXI PXIe Ethernet controllers. In this case study, we will discuss the advanced methodology used by VTI in the creation of this system.

With advances in technology and subsequent demands on manufacturing and production, Automated Test Equipment (ATE) systems are becoming more widely used across a range of industries including automotive, avionics, aerospace and defense.

ATE systems are efficient and can be incredibly useful, eliminating human intervention as a potential source of error and allowing quick and accurate testing that can increase production throughput. However, it can become a complicated task to properly set-up an ATE system to optimize test cycle times without sacrificing test quality. Developing an ATE system takes time, and there can be different approaches to achieve the same goal. Misusing an approach can cause the system to become less efficient, contributing to more time spent or more resources used to complete the task. In this white paper, you will learn how VTI has incorporated LXI extended triggering functions in instrumentation to facilitate the design of highly efficient automated test systems.

VTI has expanded its growing line of RX series of rugged instrumentation with the introduction of the RX0124. The RX0124 is a high performance rugged bridge/strain measurement instrument that can be distributed near test articles via LAN with precise synchronization of acquired data. This allows users to realize highly accurate fatigue and strain measurements on large structures in harsh environments such as engine test cells, with the simplicity and low cost infrastructure of Ethernet.

The RX Series family of instruments delivers rapid integration and precise synchronization of multiple devices through the IEEE-1588 Precision Time Protocol standard. All measurement data is returned with IEEE-1588 timestamps with typical accuracies of <100 ns ensuring that acquired data is tightly correlated across the measurement system.

The introduction of the PMX04-DAQ and PMX04-MOD this month brought precision data acquisition and modal analysis to portable applications.

The PMX04-DAQ includes the EXLab data acquisition software, creating a portable, turn-key DAQ solution for verifying designs of electromechanical products. The PMX04-MOD comes equipped with the powerful X-Modal III modal analysis software for portable modal analysis. These two turn-key, light-weight portable systems come equipped with VTI's EMX digitizers that enable users to achieve high speed data acquisition and modal analysis from any location.

March brought with it the latest release of X-Modal - version 3.4. X-Modal is an experimental modal analysis research software package developed by University of Cincinnati SDRL in conjunction with a group of sponsoring companies and the UC-SDRL Research Software Consortium.

When used with any of VTI's Smart Dynamic Signal Analyzers (DSA's), X-Modal allows users to perform turn-key modal analysis with intuitive, task oriented user interfaces, extensive MIMO modal parameter estimation algorithms, parallel display capabilities, flexible data management, and embedded DAQ capabilities.

Some of the feature upgrades in version 3.4 include: Read more about the latest version of X-Modal here.
