Measuring Digital MEMS Microphones – Frequency, Sensitivity, and Power Supply Rejection (PSR) Performance
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
