HT6022BE是一个经济、低端的示波器,无法与高端示波器相比。

以下是一些限制和注意事项。


Hantek6022BE没有内置的逻辑分析仪,它的线路板上有预留空间,但是没有焊接相应逻辑分析仪器件。而在Hantek6022BL上,则有逻辑分析仪。

其固件没有放在PCB板上,而是每次示波器连接到电脑时,从电脑上安装的驱动中下载固件。

一个在1x档位上的5伏的输入信号将在909K和100K之间的节点以及在ADC输入端给出一个500豪伏的信号。任何大于500豪伏的信号都会被ADC剪切。这就意味着探头在1x档位时过载小于35伏的输入都是是安全的。(根据指标,在1x档时,最大输入为正负35伏;在10x档时,最大输入为正负350伏。)

使用虚拟示波器,需要谨记:
Hantek6022BE示波器与USB接口分享一个地,也就是与你的电脑、显示器、甚至是洗碗机、冰箱等分享着一个地... ...
建议:确保隔离,使用电池供电的笔记本电脑,不要连接外接显示器和其他联网使用的电器设备。或者一个隔离变压器。

Hantek6022BE示波器的实际输入电压范围是正负5伏信号。即当探头达到1x档时,-5V至+5V的信号可以被显示;当探头档位在10x时,可显示-50V至+50V;在100x档时,显示-500V至+500V等等。
如果输入电压超过5V,就会出现剪切信号。选用适合的探头,可以测量高于5V的信号。

如下是当输入电压信号峰峰值11.5V时,出现的信号剪切图片。
