Utilizes a Call Box for simulating network connections with the Device Under Test (DUT).
Features adjustable frequency response settings for compliance testing.
Includes acoustic test interface equipment compliant with ITU-T P.58 and IEEE Std 269.
Tests handset positioning with 2N and 8N mounting forces for different user scenarios.
Analyzes test signals in 1/12 octave bands for detailed performance evaluation.
Ensures output distortion and frequency response meet stringent technical requirements.

Często zadawane pytania:

What is the purpose of the TIA-5050-2018 Volume Control Test System?

The system is designed to measure active speech levels and conversational gain in wireless handsets, ensuring compliance with industry standards for both narrowband and wideband transmission modes.
What codecs are used for testing in narrowband and wideband modes?

For narrowband mode, the AMR speech codec at 12.2 kbit/s is used. For wideband mode, the AMR-WB speech codec at 12.65 kbit/s is employed.
How does the system handle handset positioning during tests?

The system tests handset positioning with 2N and 8N mounting forces, simulating different user scenarios, including those with and without hearing devices.
