The MTEST60 is a TEF software module for
production line testing of microphones and capsule
prototypes under development and also to test production
microphones to see whether they meet tolerances for sensitivity,
frequency response, and off-axis attenuation. "Mictest" gives
the tools to define and implement
standards in an ordinary room without the cost of a conventional
anechoic chamber, or costly vibration isolated rooms. The
program has added many of the functions previously only
available in Speaker Test, including customized envelopes for
Pass/Fail production testing. Up to 3 separate envelopes are
available to grade microphones based on the microphone response.
For production test you create and save the production
tolerances (envelopes) for a particular models frequency
response, sensitivity, off axis attenuation and set up the
production test sequence.
In the Test Sequence (Measurement Sequence) the computer will
load frequency-response and sensitivity envelopes, run a TDS
sweep, and show a prompt such as PASS, FAIL, or other user
defined prompts. |
