The 4915 Antenna Coupler is a unique solution enabling reliable serial testing of mobile phones. By always fixing the phone in the same position on the coupler, repeatability of measurement results can now be significantly increased, resulting in accurate and valid pass/fail verdicts. For service factories, this improvement means that unnecessary repair costs decrease. The mobile phone frame allows safe and extremely fast handling, resulting in higher throughput in both incoming inspection and final test. Service factories secure the investment in the coupler by exchanging the frame for another type of mobile without requiring a complete new antenna coupler.
