Voice Testing System for Mobile Phones

Voice Testing System for Mobile Phones Type 6712 provides a new and improved approach to fast, reliable and efficient voice testing of Mobile Phones. Type 6712 is a powerful tool in the entire development and production process of mobile telephones.

The Voice Testing System is software controlled, allowing measurements to be made consistently and with a minimum of operator interaction. High-level users can use the instruments and software interactively to develop their own tests for parameters not covered by the standard test cases.

Uses

Voice testing of mobile phones covering:

• Research and development of mobile phones
• Quality assurance and sample testing of mobile phones
• Inspection and validation of mobile phones

Features

• Pre-programmed tests run individually or as a complete sequence with minimum operator interaction
• Advanced noise excitation test methods including artificial speech signals (ITU-T Rec. P.50)
• Real-time filters (IEC225) and sound level measurements (IEC651) for noise and speech signal analyses
• Digital equalisation of Mouth Simulator
• Automatic test report generation
• Flexible user interface enabling users to design test cases
• Supports measurements with HATS (4128D) for realistic handset evaluation
• Adaptive test methods for sine excitation ensure highly accurate results

Voice Testing System for Mobile Phones Type 6712 supports a wide range of international standards required for testing the acoustical performance of mobile phones.

Standards currently supported are:

• EN 300 903 (GSM 03.50)
• 3GPP TS.51.010 (GSM 11.10 chapter 30)
• 3GPP TS.26.132 
• CTIA Certification Program Test Plan (section 7)

• 3GPP2 C.S0056-0

The test cases typically required by the standards are:

• Receiving Sensitivity Frequency Response
• Sending Sensitivity Frequency Response
• Receiving Loudness Rating
• Sending Loudness Rating
• Talker Sidetone (STMR)
• Sidetone Distortion
• Receiving Distortion
• Sending Distortion
• Out of Band Signals
• Receiving Noise
• Sending Noise
• Echo Return Loss (ERL)
• Stability Loss
• Ambient Noise Rejection (ANR)
• Listener Sidetone Rating (LSTR)

and for each standard the appropriate selection of required test cases are included in the application software.
