• 性能测试性能测试强调长时间、重复或者高强度的进行某些操作，来验证产品在各种极限条件下的表现。性能测试隶属于软件测试中的系统测试，它对软件在集成系统中运行的性能行为进行测试，旨在及早确定和消除软件中与构架有关的性能瓶颈。3、手机中的性能测试分类(1)时间相关的性能测试可分为长时间保持测试和限定时间反应测试(2)次数相关的性能测试是测试终端重复稳定地进行某项功能的能力(3)并发测试主要是测试终端同时进行多项业务时表现出的处理能力，例如同时进行CS域语音业务和PS域**业务，或者在MP3播放的同时进行

•  
• UMTS security variables within the USIM match the default 
• Setup time is reduced because the USIM is configured with the same default IMSI and PLMN values broadcast from the Wireless Test Set.
• For dual-mode testing, GSM speech loopback is supported for GSM Bit Error Ratio (BER) measurements.

 USIMs support operating voltages of 1.8, 3 and 5 volts (class AB) and are based on the Gemalto "GemXplore 3G V2.2",. If desired, you can further modify the USIM's settings using the Gemalto "GemXplore Admin for 2G (with GemXplore 3G Option)" software, which you must purchase separately from Gemalto.
