  • Instrument microphones
  • MEMS microphones
  • Build-in microphones in mobile phones or headsets
  • Microphone components

Setup with 1x Microphone

FX100 Configuration One Microphone
This setup verifies single microphones in a basic test environment. The sound source is equalized for a flat frequency response using a reference measurement microphone.

Procedure:
  • Calibrate and equalize the sound source by using the reference measurement microphone M2010
  • Start microphone measurements with the equalized sound source

Setup with 1x Microphone and 1x Reference Microphone

FX100 Configuration Two Microphone
This setup verifies single microphones in a test environment with equalized sound source and reference microphone. The measurement provides results relative to the reference measurement microphone, thus the results are immune to any changes in the environment such as temperature or humidity.

Procedure:
  • Calibrate and equalize the sound source by using the permanently-installed NTi Audio reference microphone M2010
  • Start microphone measurements with the equalized sound source and the reference microphone M2010

Setup for Multiple Microphones with Switcher

FX100 Configuration Multiple Microphone
This setup verifies several single microphones in a sequence.

Procedure:
  • Calibrate and equalize the sound source by using the NTi Audio reference measurement microphone M2010
  • Start microphone measurement sequence with IS-1002 audio input switcher

Turntable Setup for Polar Pattern Measurement

FX100 Configuration Turntable
This setup records the polar plot of a single microphone on a turntable in a test stand with equalized speaker.

Procedure:
  • Calibrate the SPL of the sound source by using the NTi Audio reference measurement microphone M2010
