嗨!
我最近在eBay上买了一台旧的8590A。 它工作正常,但缺少HPIB / GPIB连接器和电缆。 切口上面有一个粘性挡板,因此看起来电缆在某些时候被广告删除了。 卡片在那里,并且在分析仪识别它时似乎正在工作。 据我所知,该电缆是GPIB的标准IDC 24引脚。 虽然IDC连接器的引脚排列不是标准的GPIB,但我已经跟踪了连接并记录在案。 我有两个问题:1。有没有人有电路板或电缆的原理图,所以我可以验证我记录的内容? 2.电缆应如何在设备内部布线? 没有太多的自由空间。 提前致谢! 以上来自于谷歌翻译 以下为原文 Hi! I recently bought an old 8590A on eBay. It works fine, but the HPIB/GPIB connector and cable are missing. The cutout has a adhesive blanking plate over it so it seems that the cable was advertrntly removed at some point. The card is there and appears to be working as the analyzer recognises it. The cable is a standard IDC 24 pin to GPIB as far as I can see. Pinout of the IDC connector is not the standard GPIB one though, but I have traced the connections and documented. I have two questions: 1. Does anyone have a schematic of the board or cable so I can verify what I have documented? 2. How is the cable supposed to be routed inside the unit? There is not an awful lot of free space. Thanks in advance! |

听起来您需要服务指南附图中的图片。
有一条带状电缆连接到电路板上,后面板上还连接有GPIB连接器。 从服务指南看,此程序集的部件号看起来是08590-60018。 对不起,但我根本找不到任何原理图,但这应该解决了电缆如何到达后面板连接器的秘密......我做了谷歌搜索部件号,我确实看到了至少一个 点击似乎是出售的合法报价。 最好的问候,迈克 以上来自于谷歌翻译 以下为原文 It sounds like you need what is pictured in the attached drawing from the service guide. There is a ribbon cable attached to a board that also has the rear panel GPIB connector attached to it. From the service guide it looks like the part number of this assembly is 08590-60018. Sorry, but I couldn't find any schematics for this at all, but this should solve the mystery of how the cable gets to the rear panel connector... I did a google search for the part number and I did see at least one hit come up that appeared to be a legitimate offer for one for sale. Best regards, Mike 附件

(0850-90316,我能在网上找到的唯一一个)。 无论如何,如果我能找到一个完整的电缆和支架,价格合理,那就容易多了。 我会看看。 编辑:AndersG于2015年2月17日上午11:59啊..因为这是错误的手册。 正确的是08590-90109:http://www.keysight.com/upload/cmc_upload/All/8590AServiceGuide.pdf编辑:AndersG于2015年2月17日下午11:32我猜测08590-60052 GPIB的手册 OPT Kit将包含接线说明,但我无法在网上找到它。编辑:AndersG于2015年2月17日下午11:48 以上来自于谷歌翻译 以下为原文 Thanks a bundle. Dunno why I did not find that in the service guide? (0850-90316, the only one I could find on the web). Anyway, If I can find a complete cable and bracket, for a reasonable price, then it is so much easier. I will look. Edited by: AndersG on Feb 17, 2015 11:59 AM Ah.. Because it was the wrong manual. The correct one is 08590-90109: http://www.keysight.com/upload/cmc_upload/All/8590AServiceGuide.pdf Edited by: AndersG on Feb 17, 2015 11:32 PM I Guess the manual for the 08590-60052 GPIB OPT Kit would contain wiring instructions, but I have been unable to locate it on the web.

好。 取得了一些进展,电缆引脚似乎是:1,2,3,5,7,9,11,13 = gnd 4 atn 6 srq 8 ifc 10 ndac 12 nrfd 14 dav 15 ren 16 eoi 17 d8 18 d4 19 d7 20 d3 21 d6 22 d2 23 d5 24 d1我发现有一家供应商提供的电缆+支架只需50多美元,但最低订购量为200美元,运费将额外收取50美元。 一个gpib连接器和一个IDC连接器将让我回到不到10美元:)不知道是否应该屏蔽电缆? 当空闲时,OTOH应该不受GPIB电缆的辐射。 以上来自于谷歌翻译 以下为原文 OK. Made some progress, cable pinout seems to be: 1,2,3,5,7,9,11,13 = gnd 4 atn 6 srq 8 ifc 10 ndac 12 nrfd 14 dav 15 ren 16 eoi 17 d8 18 d4 19 d7 20 d3 21 d6 22 d2 23 d5 24 d1 I found one vendor that offered the cable+bracket for just over 50$, ut they have a minimum order of 200$ and shipping will set me back an extra 50$. A gpib connector and an IDC one will set me back less than 10$ :) Wonder if the cable should be screened? OTOH should the be no emissions from the GPIB cable when idle. |
