嗨,我正在尝试修复ESG信号发生器。
错误很可能是在4400 60002上,其中有一些MMIC标记为641.是否有人有CLIP或知道这是什么类型的MMIC? 可能是MGA-64135,(?)。此板的输出还有另一个ic。 它可能是U203,但我不确定。 这是什么类型的IC? 带有8个引脚的金色扁平封装。故障是9V是否被这块电路板严重负载,也许有人之前看到过这个错误?问候Jens 以上来自于谷歌翻译 以下为原文 Hi, I'm trying to repair a ESG signal generator. Error is most probably on board 4400 60002 where there are some MMICs marked 641. Does anybody has a CLIP or knows what type of MMICs this is? Could it be MGA-64135, (?). There is also another ic at the output from this board. It might be U203 but I'm not sure. What type of IC is this? Golden flatpack with 8 pins. The fault is that the 9V is badly loaded by this board and perhaps somebody has seen this error before? Regards Jens |

嗨Jens - 我没有给你积极的答复。
ESG D4000A是一种过时的产品,没有可以找到或获得的CLIP。有缺陷的电路板E4400-60002也无法购买。 关于这些坏消息我很遗憾。 以上来自于谷歌翻译 以下为原文 Hi Jens - I do not have a positive reply for you. The ESG D4000A is an obsolete product, and there is no CLIP that can be found or obtained. The defective board, E4400-60002 is also not available to purchase. Sorry for the bad news. |

醉狼工作室 发表于 2019-3-26 16:19 嗨,这个周末我再次看了ESG。 在废弃设备之前 - 有没有人有E4400-90336.pdf? 显然这是原理图,也许这将是我单位的最后一次机会。 ESG将仅用于火腿无线电实验,因此没有商业利益。 这次当我开始它时,屏幕上根本没有任何文字。 它似乎很明亮,但对比度/光线无法调整 - 计算机故障也是如此? 此致,73 Jens 以上来自于谷歌翻译 以下为原文 Hi, I looked at the ESG again this weekend. Before I scrap the unit - does anybody have the E4400-90336.pdf? Apparently this is with schematics and perhaps this would be the last chance for my unit. The ESG will be used for ham-radio experiments only so there is no commercial interest in this. This time when I started it there isn't any text at all on the screen. It seems to get light on but the contrast/light can't be adjusted - computer failure too? Regards, 73 Jens |

zhihuaczh 发表于 2019-3-26 16:27 嗨Jens - 这是ESG-C服务指南链接: - http://cp.literature.agilent.com/litweb/pdf/E4400-90335.pdf在服务指南中,您可以参考前面板显示屏故障排除以帮助 你在看到的显示问题。 问候 - 以上来自于谷歌翻译 以下为原文 Hi Jens - Here’s the ESG-C Service Guide link:- http://cp.literature.agilent.com/litweb/pdf/E4400-90335.pdf In the Service Guide, you can refer to the Front Panel Display Troubleshooting to aid you in the display issue that you are seeing.

zhihuaczh 发表于 2019-3-26 16:27 你好Jens RE:E4400B电路图纸你有没有成功找到全部或部分手册E4400-90336.pdf? 我也有一台E4400B,这次是怀疑有故障的脉冲模式电路,我正在为A9输出板制作电路图,& A11参考板,(ESG-A版本)。 再次,发电机是用于火腿无线电使用,所以除非我能找到图纸,它将超出经济修复,耻辱作为一个非常好的发电机,但我不能证明400usd完整手册。 任何信息都非常感谢percival.harry(at)gmail.com问候Harry 以上来自于谷歌翻译 以下为原文 Hello Jens RE: E4400B circuit drawings Did you ever succeed in locating all or part of the manual E4400-90336.pdf? I too have a E4400B, this time with a suspected faulty pulse mod circuit, I'm after circuit drawings for the A9 output board, & A11 reference board, (the ESG-A versions). Again, the generator is for Ham Radio use, so unless I can locate the drawings, it will be beyond economic repair, shame as its a very nice generator, but I couldn't justify the 400usd on the full manual. any info much appreciated at percival.harry(at)gmail.com Regards Harry |

山川1998 发表于 2019-3-26 16:49 你好Harry,我很抱歉答案非常晚,但我通常不会查看论坛的信号源部分。 我没有找到E4400-90336.pdf,我也会将我的发电机用于火腿收音机。 我的部队报废了,我无法以合理的价格买到任何备件。 73 Jens,SM7OVK 以上来自于谷歌翻译 以下为原文 Hello Harry, I'm sorry for a very late answer, but I'm normally not checking the signal source part of the forum. I didn't found the E4400-90336.pdf and I would also use my generator for ham radio. My unit is scrapped and I couldn't get my hands on any spareparts at resonable prices. 73 Jens, SM7OVK |

zhihuaczh 发表于 2019-3-26 16:59 这很可能是迟到的帮助,但我看了原理图,是641是MGA-64135 U203是最后的放大器。 9v开车吧。 这个电路板(部件号为E4400-60002合成器)可在ebay上购买,我可以修复这些ESG,但是按照这个价格,我只需要购买电路板并继续使用。 也许取下最后的放大器,看看供应是否恢复。 我希望这有帮助。 Joe Lubecky测试设备 以上来自于谷歌翻译 以下为原文 This is most likely to late to help but I looked at the schematics and Yes the 641 is MGA-64135 The U203 is the final amp out. 9v driving it. This board (p/n E4400-60002 Synthesizer) is available on ebay for 300 I repair these ESGs but for that price I'd just get the board and move on. maybe remove the final amp and see if supply comes back up. I hope this helps. Joe Lubecky Test Equipment Plus |

旧线程,但如果有人可以为E4400系列的信号提供CLIP(或带有原理图的文档),那将会很棒。
E4400-90336显然是名字,但Googling一无所获......编辑:显然E4400-90336适用于E4400B系列。 我想要E4400A& B.编辑:BurkettC于2016年1月29日下午7:13 以上来自于谷歌翻译 以下为原文 Old thread, but it would be great if someone could make the CLIP (or doc with schematics) available for the E4400 series of sig gens. E4400-90336 is apparently the name but Googling has turned up nothing.... Edit: Apparently E4400-90336 is for the E4400B series. I'd like the E4400A & B. Edited by: BurkettC on Jan 29, 2016 7:13 PM |
