HP公司最近发布了业界第一种可自动检测敏感连接开路的移动通信DC源(可测试电源与设备的连接线在何处断开或脱落)。这种HP新开发的技术增强了HP 66311B移动通信DC源的功能,使蜂窝电话制造商能检测到敏感线连接的永久性或暂时性断开。对连接断开的自动检测能使测试工程师避免进行不正确的电池充电器核准,得到不精确的测试结果,以及由于较大的电压瞬间跌落造成电话的低压关断。
HP recently unveiled the industry’s first DC-DC mobile source that automatically detects open circuits with sensitive connections that test where the power and equipment cables are disconnected or missing. This newly developed HP technology enhances the capabilities of the HP 66311B mobile communications DC source to enable cellular phone manufacturers to detect permanent or temporary disconnections of sensitive line connections. Automatic detection of a connection disconnect allows the test engineer to avoid incorrect battery charger approval, inaccurate test results, and low voltage shutdown of the phone due to large voltage drops.
