The SO analyser is M+P International's versatile real-time analyser for noise and vibration measurement, analysis and reporting in the field and in the lab
SO analyser release 3.2 is scalable and offers modules for signal processing and time data recording, modal analysis, impact testing, rotating machinery, vibration control analysis as well as for vehicle pass-by-noise testing.
It introduces a lot of new useful capabilities and enhancements such as further extensions to the reporting wizard, multiple tacho/frequency inputs, operational modal data processing, new time history display/recording/post-processing functions, dynamic strains support for National Instruments cards, vehicle pass-by-noise testing fully compliant to the recently introduced 03 revision of the ECE and ISO automotive drive-by-noise test procedures, and more.
The new Multiple tacho/frequency inputs feature, included in the standard software, offers a low-cost solution to those applications that need a simple spectral mapping capability; for machinery applications as well as for swept sine analysis.
The SDOF and MDOF wizards now include the option of processing operational modal data which is for cases where a structure is self-excited or where input forces are not known, applications include automotive testing using road loading, bridges using traffic passing, shakers using random or swept sine inputs, etc.
The reporting functionality has been further extended, simplified and made faster, eg, automatic batch/page/mix report generation and the handy Fixed Traces feature for overlaying upper/lower limit lines on vibration control test reporting.
The latest SO analyser revision also provides dynamic strain support for National Instruments cards: acquisition set-ups of input channels now support the strain gauge settings for the NI USB-9237 and the NI PCI/PXI 4220 cards (1/4, 1/2 and full bridge selections, completion resistor settings, supply voltages and front-end low-pass filtering).
Users of M+P International's VibControl system can now use both their vibration controller and SO analyser in parallel on the same VXI chassis.
The GPS-based pass-by-noise testing system was updated to the 03 revision of the ECE and ISO automotive drive-by-noise test procedures which added significant new measurement requirements over and above the old procedures.
