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.

Is it possible to connect the BNC outer to ground when using a P8000?

A question was recently posed regarding the grounding conditions of a BNC type input. The shield or outer of a BNC cable or connector is not connected to the chassis or ground. What would happen if it was connected to ground?

Differential (more…)

Creating calculated signals with DATS Acquisition

Case Study: What can I do if the transducer I am using has a non-linear sensitivity over its measuring range?

Abstract

Recently a PROSIG user wanted to measure a specific temperature parameter on a running engine. The transducer being used was one of the engine sensors built into the engine operating system to minimize engine emissions and maximize fuel economy. Unfortunately, the sensitivity of this transducer was not constant over the desired temperature range. The question then became, how can the output from this non-linear transducer be used to accurately measure the desired temperature parameter? (more…)

Should I use 50 Ohm or 75 Ohm cables with a Prosig P8000 system?

BNC CableUsing 50? or 75? cable will not have any negative effects on the P8000 at all. (Generally speaking, only large voltages will damage the P8000). The impedance of the cable can only ever effect the signal the cable is carrying. (more…)

How To Analyze Noise & Vibration In Rotating Machines

In this article we will look at the basic steps needed to measure noise & vibration in rotating machines. We won’t look in great detail at some of the techniques involved – we deal with these elsewhere on the blog. This material is suitable for a newcomer to the field who understands the basic concepts of noise & vibration analysis, but has not dealt with rotating machinery before. (more…)
