Final Sound Testing
For auditory testing of microphones and speakers of mobile phones, rapid Testis the best choice. The optional Buzz and Rub detection make sure a centpercent relation to the human ear, so test making by human operators issuperfluous. It is the main as well as first solution to conduct an automatedquality test, which is dependable to the manufactures. Phantom power supply isincluded for the microphone measurement in the system. The acoustic testing isan important phase of ;go through the following common measurements.
> Sound Pressure Level (SPL)
> Buzz & Rub of transducers
> Rating Loudness
> Frequency Response
> Microphone sensitivity
Testing of Ring
Rapid Test detects the frequency and level of ring tones and surprisinglyit works for narrow bands. It calculate the absolute SPL and gauge microphoneby M2010 and NTTs ?? respectively. No need to use power supply or externalamplifier as microphone can be connected with RT-2M directly.
Alert Vibration Testing
A vibration sensor (NTI accessory) with RT-2M together detects the vibra callactivator function. The vibration energy and frequency takes 500 ms to measure.Conversion into acceleration or RPM can be easily calculated directly.
Analysis DTMF Keypad
DTMF fully supported by RT-2M.DTMF is used for telephone frequency dialing.
