## Vibration Measurement Techniques: A Comprehensive Guide

[An Introduction To Vibration Analysis - Part 2] Introduction This post on vibration measurement techniques is the second in our series, introducing vibration analysis. Future posts will continue the exploration…

## Basics of Vibration Analysis: A Technical Dive

[An Introduction To Vibration Analysis - Part 1] Introduction For professionals delving into the worlds of automotive, aerospace, or industrial engineering, vibrations are not just mere oscillations; they're a symphony…

## Understanding CAN Bus: The Nervous System of a Modern Vehicle

Understanding CAN bus (Controller Area Network Bus) is essential to modern automotive engineering. The CAN bus, and its variants, are now universal across the automotive industry and beyond. On many…

## Does Prosig hardware support strain gauges? And which types?

I’m often asked whether the Prosig systems support strain gauges. And what configuration of strain gauge bridges are supported? The answer is all types of all configurations. (more…)

## Example of performing a Moving Average

This tutorial guides a DATS user through the steps required to perform a moving average on a given signal. The tutorial explains the concept of the ‘Integration Length’ and the ‘Output Interval Step’.

Initially a signal is required to perform the moving average on. In this tutorial a sine wave will be generated. A sine wave is generated using the parameters shown in Figure 1.

## Averaging Frequency Response Functions From A Structure

The following was written by Adrian Lincoln in response to a customer asking about averaging Frequency Response Functions (FRFs) Further to your reply it should be noted that there is…

## Enabling Audio Playback in P8000 Acquisition Software

It is possible to enable audio playback to listen to audible frequencies while recording or monitoring when using a P8000 and the V4 Acquisition software.

## What is the maximum analysis frequency for a waterfall in DATS?

The maximum analysis frequency is always half the sample rate of the input signal.

So if your data is captured at 50kHz the maximum analysis frequency will be 25kHz.

## Creating Order Plots Using The DATS Rotating Machinery Software

In this tutorial we will be creating order plots using waterfall and intensity displays using use the DATS.toolbox and Rotating Machinery Analysis option.

To begin, a noise, vibration or other signal of interest should be captured along with a tachometer signal.

In Figure 1 we have loaded a time series (in this case an acceleration signal) and a time series of a tachometer pulse train into the DATS software.

## Making an Orbit Plot

## How to use an Analogue Channel with Tachometer Signals on the P8000

When using an analogue channel input channel of a P8000, with a tachometer sensor, is it possible to utilise the tachometer processing functions as you would if you were using…

## What is waterfall frequency spacing? And how does the DATS parameter ‘Requested Frequency Spacing’ work?

Let us try to understand what waterfall frequency spacing is. Waterfall frequency spacing is the gap between spectral lines in an FFT plot.

For example, if you had an analysis frequency of 0Hz to 100Hz and 100 spectral lines, then Frequency Spacing is 1Hz.

So why is there a ‘Requested Frequency Spacing’ and an ‘Actual Frequency Spacing’? (more…)

## What is “waterfall smearing”?

When analysing a waterfall or performing order analysis it is important to consider the frequency resolution or the frequency spacing.

There is often a desire to increase the resolution to finer and finer detail. But that is a process of diminishing returns, and actually fraught with danger. And that danger is waterfall smearing. (more…)

## Is it important to consider the cable resistance when using strain gauges?

The cable resistance can be a significant factor in the accuracy of the overall measurement. It is very important indeed to consider this point. Prosig software allows the cable resistance…

## What engineering decisions are made by measuring a power spectrum?

By power spectrum we are talking about an ASD (Auto Spectral Density) or PSD (Power Spectral Density). In fact PSD is often used when really ASD would be more correct.

Taking any signal and performing a frequency analysis using an ASD or a PSD will give the energy over a range of frequencies. (more…)
