James Wren (Prosig UK) explains how to store FRFs, coherence and/or time series data in modal hammer testing using Prosig’s P8000 & DATS software.
James Wren (Prosig UK) explains how nodes, components & structures are used in modal hammer testing using Prosig’s P8000 & DATS software.
Here at Prosig we’ve been using the hardware & software on the preview versions of Windows 8 for a few months now. Since the final release hit the streets recently we can confirm that there are no known compatibility issues with DATS, P8000 and the new operating system.

A user has three signals captured using a triaxial accelerometer and asked “What is the simplest way to get the XYZ resultant from run-up file?” He had tried forming a resultant of the raw time histories, but didn’t fully understand the resultant time history.
Of course, the correct way of processing the data is to calculate the individual waterfalls from the x, y & z data and then calculate a resultant waterfall. Continue reading
A user recently asked…
I want to show the principle stress increments on the left side of the graph and the load scale on the right side of the graph. I can do this with some other programs but cannot find a way to do it in DATS for Windows.
Is this POSSIBLE?
One of Prosig’s engineers was recently creating a complex worksheet application that required some complicated arithmetic to be performed on values calculated in the worksheet. Worksheet (or global) variables are ideal for this. The Variable Mods DPU also has an expression evaluator built in. Consider the following worksheet that takes a Named Element from two signals and sums them. Continue reading
Generally when developing and testing bearings a simple step by step procedure should be followed.
I’m sure many users will have been in this situation. You need an analysis function, you know it’s in DATS, but you can’t remember where. One of the major strengths of the DATS package is the depth of analysis functions it provides. Unfortunately, when you have a deadline and can’t find the function that you want that isn’t much help. But assistance is at hand… Continue reading
