示波器模块

PICO示波器使用方便,只需插入任何台式电脑或笔记本电脑的USB口上。PICO有两个与众不同的特点,第一是分辨率(清晰度),第二是存储器深度。

大多数数字存储示波器通常只有8位垂直分辨率和不高的DC精度,而PICO的精度达到1%并且有12位分辨率(清晰度)。因此PICO的垂直分辨率达到4000点,而当前市场上的大多数汽车示波器只有100或200点。同PICO的高分辨率一样,它还有一个巨大的512,000读取波形缓存器。这两个特点使它能够捕捉复杂的,大型的信号并且还能够放大你感兴趣的区域,显示信号波形上的细节。

通过配套的软件,PICO还能够用作示波器和频谱分析仪。用作示波器(检查ABS,喷油嘴和点火波形)很有用,但是频谱分析仪也是非常有用的汽车工具。它特别适合于调整,测试和修理汽车音响,如果接上一个振动传感器,它可以帮助寻找磨损的运动部件例如轴承,而不需要拆卸工作。

PICO汽车示波器强大的功能用于测量汽车电路系统和机械系统所产生的信号,包括初级/次级点火,电脑控制系统,以及CAN总线信号。这种先进的高分辨率示波器能够采集高达512,000 个样本,你可以在宽大的电脑屏幕上看到汽车点火信号和ECU信号波形的细节,为你提供最好的机会去发现令人头疼的间歇性故障。

PICO示波器有两种用法:移动应用和车间应用。当用于开车路试时,笔记本电脑通过USB连接线向示波器提供电源,同时示波器通过USB连接线将采集到的数据在电脑显示屏上显示出来。你可以更容易诊断时有时无的间歇性故障。

全部测试选项由菜单驱动
菜单中含有超过60项预先设置的测试选项和参考波形,使诊断快速和容易。你只须在菜单中选择你要测试的传感器或电路,示波器就会自动设置好所有测试参数(最佳时基,量程等),并且给出详细的测试步骤和参考波形。

点火分析
点火分析功能能够全面分析点火系统的工作状态。你可以在宽大的电脑屏幕上观察初级/次级点火的清晰波形,测量点火电压,燃烧电压和燃烧时间,闭合时间。点火线圈的振荡也能清晰显示。

COP点火分析
对于越来越普及的一火花塞一点火线圈(COP)独立点火系统,用标配的电流探头和适配器测试初级电路的电流和电压波形。

2/4通道示波器
PICO示波器专门为现代电脑控制的汽车而设计,因此特别适合于诊断最难捉摸的故障。先进的功能满足你对高端示波器的需要,但是为各种汽车部件预先配备的设置使任何人都能快速容易地使用。不同通道用不同的颜色显示波形,清楚明了。该示波器也有一个标准波形库。当你选择一项测试时,都会首先加载一个标准波形,并且弹出测试帮助文件。当你点击“开始”按键时,示波器就会以预先配置的最佳设置采集信号和显示信号波形。

技术支持
每台示波器的软件都包含超过60个主题的技术文件和波形。我们的技术专家队伍随时准备帮你购买你需要的组合并回答你的任何技术问题。宏科还定期举办系列培训课程。主要针对汽车故障诊断。这些课程将告诉你如何更好地使用PICO示波器。
