|
Two Models to Meet the Full Range of Service Tasks
The Willtek 4200 Series phone testers are available in two versions,
each offering different levels of testing. Both models test the latest
range of GSM triple-band and optionally also quadruple (i.e. incl. GSM
850) mobile phones, including new EDGE-capable mobiles (only tuning),
and the multiple language user interface is available in English,
German, French, Italian, Portuguese and Chinese. The Automated Test
feature on both models checks a wide variety of functions and issues a
final pass/fail result immediately. Optional GPRS testing is available
in two versions; a simple Go/NoGo test option and a more comprehensive
GPRS measurement option, allowing multi slot measurements. For the US
market a new (optional) frequency is available, allowing testing of GSM
850. |
