大家好,最近购买了这种类型的示波器,但是通过测试模拟电源,它显示风扇的电源不工作,LED没有点亮,设定点显示没有电压存在。
还有18岁以上的人没有任何想法吗? 亚历克斯 以上来自于谷歌翻译 以下为原文 Hi all, recently acquired this type of scope, however from testing the analogue power supply it shows that the supply for the fans is not working, the led is not lit and the set points show there is no voltage present. Also the 18+ is not working Any Ideas ? Alex |

电路图有用,如果这些可用,它们不包含在服务手册中,如果它可以是一个简单的修复,这似乎是浪费!
以上来自于谷歌翻译 以下为原文 The Circuit diagrams would help if these were available, they are not included in the service manual, it seems a waste if it could be a simple fix ! |

您好redders03您是否找到了模拟电源的电路图? 我有一台必须相同的HP54112D。 如果你感兴趣 ? 我的HP54112D上的电源也有类似的问题。 U1 PWM控制器与其他一些HS组件分道扬.. 我正在寻找这个IC(U1是XR 1826-1120)。 但它并不容易获得。 如果有人对此电路有任何信息,我会很高兴。 对不起我的英文,我是法国人问候Pulsingwave1编辑:Pulsingwave1于2013年8月3日9:22 AM 以上来自于谷歌翻译 以下为原文 Hi redders03 Did you find the circuit diagram of the analog power supply? I have one of the HP54112D which must be the same. If you are interested ? I have a similar problem with the power supply on my HP54112D. U1 PWM controller has exploded with some other HS components. I'm looking for this IC (U1 is XR 1826-1120). But it is not readily available. If anyone has any info on this circuit, I'll be happy.
