[Video] A simple CAN-bus measurement setup
A simple tutorial that explains how to use the DATS Acquisition software to set up a Prosig P8000 to capture data from a CAN-bus. http://www.youtube.com/watch?v=XeAuntGW-O4
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…)
[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…

Do You Need To Measure Brake Noise?
The objective of the brake noise tests was to record the braking events of cars being driven on various types of road and classify those events according to their type (Groan, Creep or Squeal etc) and severity. To do this the customer needed a system capable of working for long periods inside a vehicle in fairly tough conditions (high ambient temperatures, rough road) that was both quick to install and to remove.
On previous tests a system from another supplier had turned out to be unreliable and had failed to cope with the harsh environment. The analysis processing had also proved tedious and time consuming due to the huge amount of data created when testing several vehicles over many days.
Noise & Vibration Capture with GPS Tracking
The latest version of the CAN-bus/GPS (8440) module is now available for the Prosig P8012, P8020 and P8048 systems. The CAN-bus/GPS module has been in use in the field for some time now, recording CAN-bus information for display and analysis alongside noise, vibration, temperature and other signals captured by P8000 systems. The DATS software treats all analog and CAN-bus parameters in the same way so any mixture of parameters can be selected for display in real-time and subsequent processing. CAN-bus parameters can also be used to trigger immediate and pre-triggered captures and to stop captures.
The 8440 module now has an option to capture GPS parameters in addition to the other signals. The data capture software now also supports a realtime GPS track overlayed on a map. Velocity and altitude data measured by the GPS system can also be displayed alongside any other measurement channels in realtime displays. The latitude, longitude, altitude and velocity data is stored with with all the other sensor data captured by the P8000 system and is available to view and process in the resulting datasets. These signals can then be used to classify or select data for further analysis. For example you could choose to process data when the vehicle is on a particular road or a particular section of the track, or if you find an unusual event use the GPS data to give a position and time or the event.
Made To Measure
[Updated 4th October 2021]
In this post, we will discuss the different types of transducers that can be used with the Prosig data acquisition systems and loggers. The post looks at the design and function of the different types of sensors and the applications they are normally associated with.
