Page 4: Introduction
Simcenter Qsources Low Frequency Monopole Source 2v9C.docx Introduction The Simcenter Qsources Low Frequency Monopole Source is a very compact volume displacement source. This device is especially suitable for lower frequency, reciprocal (vibro-)acoustic transfer function measurements in and around vehicles. It can be applied where monopole noise emission and compact dimensions are important. The Simcenter Qsources Low Frequency Monopole Source is a unique device due to its internal reference sensor and its large stroke at low frequencies. - Page 5 Simcenter Qsources Low Frequency Monopole Source 2v9C.docx Application area The Simcenter Qsources Low Frequency Monopole Source is a volume displacement source. They are used to perform calibrated (vibro-) acoustic transfer function measurements. The transfer functions can serve several purposes: · Acoustic modal analysis of enclosed cavities ·...

The thread adaptor can be used to mount the source onto a typical microphone stand thread (¼”-20 UNC to M6 adaptor). Fasten hand tight only. An optional tripod is optional, material code: AL0006, available through your local Siemens PLM Software office. -
Page 10: Connecting The Source
Simcenter Qsources Low Frequency Monopole Source 2v9C.docx Connecting the source Powering The source has simply one LEMO multi-pin receptacle transmitting both electric power into the source as well as outputting the sound source strength equivalent voltage. The LEMO connection is Push-Pull self-latching. Align the red dots on both ends of the connection and push the connector in axially. -
Page 11: Typical Measurement Settings
Simcenter Qsources Low Frequency Monopole Source 2v9C.docx Typical measurement settings The source can be driven with any band-limited signal between 10 and 1 000 Hz. For accurate frequency response measurements on linear structures burst random and continuous random signals can be used. Following table shows typical settings for Simcenter Test.Lab Spectral Acquisition: Specification Value... -
Page 12: Electronic Protection
Simcenter Qsources Low Frequency Monopole Source 2v9C.docx Electronic protection The Monopole source must be powered by an instrumentation amplifier like the Simcenter Qsources Measurement Power Amplifier (product code: Q-AMP230V or Q-AMP115V). A high-quality audio or PA amplifier can also be used. An undistorted RMS power output of at least 50 Watt to 8 Ohms impedance is required. -
Page 13: Stocking The Source
Simcenter Qsources Low Frequency Monopole Source 2v9C.docx Internal source strength sensor The sensor output voltage is proportional to the source volume displacement in the frequency range between 10 and 1 000 Hz. The sensor provides a stable signal, but the voltage level is in millivolts only. The sensor works in voltage mode, not IEPE, nor charge, nor Wheatstone bridge. -

Page 15: Error Diagnosis And Maintenance
Simcenter Qsources Low Frequency Monopole Source 2v9C.docx Error diagnosis and maintenance The input channel for the internal reference sensor is to be set on Voltage AC. An acoustic semi-free field FRF can be measured to check the microphones and source used for the test campaign. With all microphones bundled together at the same distance from the source, phase and amplitude should be the same in the lower frequency range. -
