當然，具體的測試仍取決於每一設計本身的好壞。最簡單的情況是通過包括呼叫建立過程的呼叫模式來進行功能測試。這種通過/不通過(Go/No-Go)測試通常覆蓋了手機的所有部件，包括天線
、功放
、接收器、振蕩器、混頻器和音頻部件。通常在生產過程中產品包裝前的最後階段進行這種功能測試，一般包括對功率準確度、頻率誤差和接收器靈敏度的測量。

接收和發射電路測試很重要

在生產測試之前，先要安裝好元器件
，將PCBdianlubanlianjiedaodianyuanbingxiazaihaoruanjian。shouxianjinxingquanmiandeceshiyibaozhengyuanqijianhelianjiegongzuozhengchang
，baokuoceshibutongqingkuangxiadedianliulaiquedingyoumeiyouduanludeqingkuang。zaijieshoudianluceshiguochengzhong，jieshouxinhaoqiangduzhishiqi(RSSI)電路對於保證準確的增益非常重要。RSSI電路一般都需要校準。最後，要對電子校正電路進行調整。如果測試失敗
，電路板將從生產線中剔除出來
，進入修理循環。

調整和校準設備要有足夠的速度和精度，否則校準過程可能會耗費太長的時間。校準過程一般要10秒至2分鍾，但如果手機的設計過程中沒有采取麵向測試的設計模式，那麼校準過程有可能延長到10分鍾甚至15分鍾時間。
