Vibration Data Integration Analysis

Simplify Acceleration Conversions with iTestSystem’s Integration Analysis Tool  Like many features in iTestSystem, the Integration Analysis tool was created because customers requested it. After all, who doesn’t like features that make the math easier? In this blog, a new series by ITM, we’ll share some details about Integration Analysis, one of the features within TestView Plus, the project based […]

Weed Out Unwanted Data with Filter Analysis

For engineers, the faster one can weed out the noise, the more efficiently one can deliver actual solutions. The software architects at Integrated Test & Measurement have added new plugin technology to  iTestSystem, their proprietary engineering measurement software platform, to enhance the user experience by allowing users to analyze data faster by filtering frequencies simply. In […]

Collect Vehicle CAN Bus data with NI 9862 and iTestSystem

Automotive and off-highway engineers and designers often need to log vehicle bus data along with vibration, strain gauge, and other sensor data during normal operation to evaluate their design.  Using data from all these sources enables these engineers and designers to pinpoint a vehicle’s response to staged or damaging events.  For example, engineers can see […]

How to Estimate iTestSystem TDMS Data File Size

When streaming high speed data over a long period of time it is important to estimate data file size to avoid filling up your drive and also to prevent producing large, unwieldy data files. I usually try to keep file sizes less than one (1) gigabyte (FAT 32 maximum file size is 4 gigabytes) to […]

Creating XLS files from TDMS Files

Precision testing generates precision data. Acquiring, accessing, and analyzing these data files allows engineers and scientists to lower product costs, engineer time-saving solutions, and even save lives. National Instruments (NI) created the Technical Data Management Streaming (TDMS) file format for high performance data streaming and retrieval. This binary file is structured for easier sorting and […]

iTestSystem Tip: Strain Gauge Rosette Analysis

When troubleshooting structural failures or validating FEA models through testing, strain gauge rosettes are used to find the full state of strain at areas of concern around the structure.  iTestSystem’s Rosette Analysis tool is used to calculate the principal strain, principal strain angle, shear strain, principal stress, and other values from strain gauge rosette data. […]

iTestSystem Tip: Sensor Auto-zero Utility Update

Our iTestSystem customers who routinely acquire data with high channel counts and data from full-bridge transducers recently requested that we update the sensor auto-zero utility to improve test setup efficiency.   In the latest version of iTestSystem, we updated the sensor auto-zero utility to include all channels that use the From Custom Scale option.  This […]

ITM adds NI-9253 Compatibility to iTestSystem

This week we added another module to the iTestSystem compatibility list.  One of our iTestSystem users recently needed to collect data from thirty-two (32), 4 to 20 mA current sensors along with their vibration measurements.  National Instruments (NI) recently introduced a new C-Series current module, the NI-9253, that was a perfect fit for this application. […]

iTestSystem Tip: Impact Hammer Setup

While iTestSystem is designed to collect data from specific sensor types like strain, voltage, current, and accel; custom signal types such as pressure, displacement, and force can also be configured by utilizing the Custom Scale functionality during the channel creation process. For example, manufacturers often need to measure the amount of force required to install […]
