Service Procedures:
1. Customer provides DUT Sample (Wireless Terminals, etc.) and Test Requirements.
2. Ascentest offers test proposal, discusses and finalizes the test plans.
3. Ascentest sends the DUT Sample to qualified Test Labs and performs all the tests.
4. Ascentest delivers test report to the customer.
5. Ascentest helps the customer to analyze the test results and provides suggestions on product optimization.
The professional testing services from Ascentest greatly reduces the customer's expenditure on R&D testing, which minimizes the customer's investment on test equipment, time and human resources, and helps finding out and correcting the product defects, and eventually improves the product quality and shortens the stringent TTM (Time To Market).
