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 (16.1.0.29), we updated the sensor auto-zero utility to include all channels that use the From Custom Scale option.  […]

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 […]

ITM adds NI-9202 compatibility to iTestSystem

The NI-9202 Voltage Input Module can now be used with the latest version of iTestSystem (16.1). The NI-9202 has excellent flexibility to meet the needs of your applications.   The module has 16 simultaneous sampled, +-10 V, 24-bit differential input channels for creating large, distributed systems in a rugged form factor. The NI-9202 has a maximum sample rate of 10kS/s and features configurable filters to eliminate noise in your […]
