Walkthrough Example #2
This walkthrough example shows you how to process impact test data with frame preview, which gives you the chance to accept or reject each frame. To obtain the data file used for the walk through example below, please contact IMAT support at imat@ata-e.com.
- Read data using the File menu. For this example, time response functions are read from the ATI file jbeam_15Z.ati, which is from an impact test run.
- Setup for triggered signal processing with frame preview by selecting 'channel' for the Triggering Method, and 'manual' for the Averaging Acceptance. Select the impact force channel for the Triggering Channel.

- Set the signal processing parameters by entering the Blocksize and selecting the 'impact/expo' Window. The impact and exponential windows parameters are entered in the Windowing dialog shown here, which is opened from the Dialog menu, or from the context menu on the Windowing panel.
- Select the measurements that will be generated during signal processing by checking the corresponding boxes in the lower right corner of the module.
- Start signal processing by clicking the START button at the bottom right of the window. A preview of each frame is plotted, and spFRF waits for you to accept or reject the frame before including it in the signal processing. spFRF switches to the Results module when signal processing is completed.
