A combination of new hardware and software improvements has extended the performance and functionality of the Pulse 9.0 multi-analyser platform system for sound and vibration testing.
A combination of new hardware and software improvements has extended the performance and functionality of Bruel + Kjaer's new Pulse 9.0 multi-analyser platform system for sound and vibration test and measurement applications.
Pulse 9.0 major hardware enhancements include a Type 3560-B compact frame with full generator output functionality and five input channels.
The generator supports all waveforms supported by Bruel + Kjaer's popular 3109 and 3110 generator module systems.
New controller modules (Type 7539 and Type 7539A) with full generator functionality and five input channels have also been introduced.
New system software enhancements enable a faster launch of Pulse applications by using dynamic redundancy checking features that ensure unnecessary files and templates are not loaded.
A tolerance curves capability is ideal for electro-acoustics customers who need a benchmarking tool or basic audit testing solution.
The tolerance curves are easy to define numerically and graphically.
Multiple curves, such as upper and lower curves, can be readily created.
The tolerance curve graphs also change colours as the measurements pass or fail.
A feature of the new software is a discrete tone calculator utility that is developed to simplify tonality testing, which is a major requirement for disk drive, fan and motor manufacturers.
Tones are often perceived as unpleasant sounds, and can pose noise emission problems for OEMs in the computer, machinery and automotive sectors.
The discrete tone calculator is ideal for any manufacturers working to ISO7779 or ECMA74 standards.
By simply dragging and dropping a function into discrete tone calculator utility the tones are located and the tone-to-noise ratio and prominence Ratio are calculated.
Another new, user-friendly feature added to the Pulse software is a graphical trigger setup utility that helps to quickly set up any "signal" trigger (excluding tachometers).
Using a simple "click and drag" method the trigger parameters can be set up to take in live data to enable the actual trigger points on a time waveform to be seen.
Pulse 9.0 supports up to 220 channels.
