For a limited time we are offering deep discounts on a system upgrade to enable you to get up to date with the latest version of SoundCheck. The upgrade offer is a simple flat rate: $3,950 for owners of SoundCheck 14 or 15, $3,250 for owners of version 16, $2,500 for owners of versions 17 […]
March 10th, 2022. 9.00am and 2.00pm Eastern US time (6.00am and 11.00am West Coast time) In this short seminar, Les Quindipan explores the use of SoundCheck for end-of-line production testing. He discusses typical test configurations and the type of measurements that can be made, how to set pass/fail limits and how to optimize tests for […]
This sequence measures the directional response of a microphone and graphs the result as a polar plot. A log sweep stimulus is played from 100 Hz to 10 kHz at each angular increment, and the acquired waveform is analyzed using the Time Selective Response algorithm. This method allows the test to be performed in a […]
This test suite contains 3 sequences to enable comprehensive testing of digital MEMS microphones: Measurement of frequency and sensitivity using a calibrated source Measurement of frequency using the ‘substitution method’, a solution for measuring frequency response where the source speaker cannot or is not equalized Measurement of power supply rejection (PSR) performance More
