我正在尝试对晶圆上的轨道测试进行连续性和隔离。
为此设计了具有76个探针触点的晶圆探测器。 我刚购买了34972a,带有两个34908a多路复用卡(80个继电器组合)。 计划是将每个多路复用器卡连接到晶片的76个触点中的一半。 一个多路复用器将采用Vdc(比如5V)并一次关闭一个继电器,而第二个多路复用器将测量/检查其连接的每个触点上Vdc的可用性。 本质上,我需要关闭(@ 101)并扫描(@ 201:240)以检查短路和隔离(购买测量不同点上的VDC),对(@ 102)到(@ 140)执行相同操作。 我的第一个问题:是否可以将外部Vdc源连接到一个34908a Mux卡(并将多路复用器与数字万用表断开)?2。 如何关闭一个多路复用器的继电器,比如说(@ 101)并在扫描和测量(@ 201:240)的直流电压时保持关闭状态? 我使用以下命令测试了一张卡的关闭一个继电器(并保持关闭以便进行测量):ROUT:CLOS(@ 130);: ROUT:CLOS? (@ 124,130,131)**并且这不会返回0,1,0作为它应该的。 但是0,0,0而不是。 请指教.RegardsL 以上来自于谷歌翻译 以下为原文 Hi I'm trying to do a continuity and Isolation of tracks test on a wafer. A wafer prober with 76 probe contacts has been designed for this purpose. I just purchased a 34972a with two 34908a mux cards (80 relays combined). The plan is to have each multiplexer card connected to half of the 76 contacts of the wafer. One multiplexer will be sourcing Vdc (say 5V) and closing one relay at a time while the 2nd one will be measuring/checking the availability of Vdc on each contact that it is connected to. In essence, I need to close (@101) and scan through (@201:240) to check for shorts and isolations (buy measuring VDC on the different points), do the same for (@102) through (@140). My first question: Is it possible to have an external Vdc source connected to one 34908a Mux card (and disconnect the mux from the Digital Multimeter)? 2. How can I close a relay of one multiplexer, say (@101) and keep it closed while scanning and measuring DC voltage from (@201:240)? I tested closing one relay(and keeping it closed in order to take measurements) for one card using the following command: ROUT: CLOS (@130);:ROUT:CLOS? (@124,130,131) **and this doesn't return 0,1,0 as its supposed to. But 0,0,0 instead. Please advise. Regards L |

您好,这适用于我的34970A / 34908A。
命令语法是正确的,我没有收到任何错误。 按预期得到0,1,0。 请检查错误。 你可以使用SYST:ERR吗? 如果你愿意。 以上来自于谷歌翻译 以下为原文 Hello, This works fine with my 34970A/34908A. The command syntax is correct and I received no errors. I get 0,1,0 as expected. Please check for errors. You can use SYST:ERR? If you would like. |

我用34908A在34970A上进行了测试:它一直工作,直到我尝试发送命令:CONF:VOLT:DC 10,(@ 102,120:130);: ROUT:CLOS(@ 129);:READ?
哪个生成错误代码+ 301使用上面的命令。 我试图从不同的继电器读取通道129上连接的直流电压。 如果我发送ROUT:CLOS(@ 130);: ROUT:CLOS? (@ 124,130,131)它返回0,0,0并返回错误代码+301。 请帮助.RegardsL 以上来自于谷歌翻译 以下为原文 I tested this on a 34970A with 34908A: It worked until I tried sending the command: CONF:VOLT:DC 10, (@102,120:130);:ROUT:CLOS (@129);:READ? Which generated error code +301 With the above command. I was trying to read the dc voltage I connected on channel 129 from different relays. If I send ROUT:CLOS (@130);:ROUT:CLOS? (@124,130,131) it returns 0,0,0 and error code +301. Please help. Regards L |

当卡上的其他通道是扫描列表的一部分时,您无法打开/关闭继电器。
要打开/关闭继电器,您必须通过发送空白扫描列表ROUT:SCAN(@)从扫描列表中释放卡,这样您就可以在切换模式下使用该卡。 您无法同时在切换模式和扫描模式下使用卡。 当插槽1中的卡处于扫描模式时,您可以在切换模式下使用不同插槽中的其他卡。 以上来自于谷歌翻译 以下为原文 You can't open/close relays when other channels on the card are part of a scan list. In order to open/close the relays you will have to free the card from the scan list by sending a blank scan list ROUT:SCAN (@), this will allow you to use the card in switch mode. You cannot use a card in switch mode and scan mode at the same time. You can use a different card in a different slot in switch mode while the card in slot 1 is in scan mode. |
