What is Resonance? (Part 2)
This article is a follow on from What Is Resonance? (Part 1) and answers some of the issues not covered in that post. How do you find the resonant frequency…
What is primary and secondary ride?
In automotive NVH circles, ride behaviour is often referred to as primary and secondary ride, but what do these terms really mean. (more…)
Should I use 50 Ohm or 75 Ohm cables with a Prosig P8000 system?
Using 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…)
There are tachometer signals available on the vehicle CAN-bus. Can I use these signals instead of connecting my own tachometer signal?
A simple question should have a simple answer and that answer is “No”.
As usual, however, life is never that simple. (more…)
What is Source Contribution Analysis (or SCA)?
How do you measure the causes of a noise or vibration with respect to several sources? Which source is causing what part of the response?
For example, how does the noise inside the cabin of a vehicle relate to the engine noise or wheel hub noise and vibration? (more…)
What is the difference between Operating Deflection Shapes (ODS) and Operational Modal Analysis (OMA)?
ODS = Motion of structure vibrating naturally (for example bridge vibration) or when excited by an unknown force (for example generator vibration). Prosig’s Structural Animation software performs ODS analysis.
OMA = Modal Analysis
Prosig’s Modal Analysis software performs OMA. (more…)
[Video] Creating order & waterfall plots

What is the difference between Transfer Path Analysis (TPA) and Source Contribution Analysis (SCA)?
Transfer Path Analysis (TPA) provides the route of the noise or vibration through the structure, not just which sources cause the response, but the route taken. This is useful for developing and improving components like engine anti-vibration mountings or suspension anti-vibration mountings. (more…)
[Video] Setting up a P8000 system to capture CAN-bus data
The P8012, P8020 & P8048 can all be fitted with the 8440 CAN-bus/GPS card. Setting up the P8000 to capture CAN-bus data is extremely simple. In the following video, James…
A Simple Step-by-step Guide To Bearing Vibration Analysis
Generally. when developing and testing bearings a simple step by step procedure should be followed.
Understanding Auto Range & Auto Gain Range
The P8000 Auto Range and the Auto Gain Range functions are often confused by users. They are not the same, but they are related. (more…)
Understanding the P8000 Auto-Zero Function
The Prosig P8000 Auto-Zero function is a powerful tool and it is well worth spending some time understanding it. (more…)

Understanding Filter Characteristics
Recently when discussing with an engineering student the characteristics of filters, it became clear that some confusion exists around this subject area. This note attempts to explain the differences between types of filter and the effects of the parameters of those filters. (more…)
