Using 50Ω or 75Ω 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. Continue reading Should I use 50 Ohm or 75 Ohm cables with a Prosig P8000 system?

A simple question should have a simple answer and that answer is “No”.
As usual, however, life is never that simple. Continue reading There are tachometer signals available on the vehicle CAN-bus. Can I use these signals instead of connecting my own tachometer signal?
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? Continue reading What is Source Contribution Analysis (or SCA)?
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. Continue reading What is the difference between Operating Deflection Shapes (ODS) and Operational Modal Analysis (OMA)?
A step-by-step introduction to creating order and waterfall plots from a time history and a tacho signal.
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. Continue reading What is the difference between Transfer Path Analysis (TPA) and Source Contribution Analysis (SCA)?
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 Wren demonstrates how it is done.
Generally. when developing and testing bearings a simple step by step procedure should be followed.
The P8000 Auto Range and the Auto Gain Range functions are often confused by users. They are not the same, but they are related. Continue reading Understanding Auto Range & Auto Gain Range
The Prosig P8000 Auto-Zero function is a powerful tool and it is well worth spending some time understanding it. Continue reading Understanding the P8000 Auto-Zero Function
