4970A和34901A自检问题

你好,我最近收到了34970A和34901A的新单位。
我正在进行自我检查作为接收检查。
34970A单元通过,但是当我将34901A模块插入34970A单元并重新运行自检时,在通过指示“MUX OPEN通道101”后会弹出一条消息。
这是正常的指示吗?
这是检查34901A模块的正确方法吗?

  Hello, I recently received new units of the 34970A and 34901A. I am running self checks as a receiving inspection. The 34970A units pass, but when I insert the 34901A modules into the 34970A units and re-run the self-test, a message pops up after the pass indication,"MUX OPEN channel 101". Is this a normal indication? Is this the proper way to check the 34901A modules?

“MUX OPEN通道101”是34970A上安装了34901A多路复用器的默认电源。
它告诉你的是,多路复用器(缩写为MUX)安装在插槽1中,第一个通道,通道101打开。
如果要对34901A进行操作验证,请参阅“34970A / 72A服务指南”中的步骤。
您可以从http://www.home.agilent.com/agilent/techSupport.jspx?pid=1000001313%3Aepsg%3Apro&pageMode=PL&t=79841.g.1&cc=US&lc下载服务指南。

这是一个相当复杂的过程,需要外部数字万用表在所有通道上进行4线电阻测量,并将结果与​​34901A规范进行比较。
您可以通过在所有通道上使用短路跳线进行2线电阻测量来缩短它。
结果将非常接近规范,但并不完全符合规定。

  “MUX   OPEN  channel 101”  is the default power on display on the 34970A with a 34901A multiplexer installed.    All it is telling you is that a multiplexer (abbreviated MUX) is installed in slot one and the first channel, channel 101 is open.    If you want to do an operational verification of the 34901A, refer to the procedure in the 34970A/72A Service Guide.   You can download the service guide at http://www.home.agilent.com/agilent/techSupport.jspx?pid=1000001313%3Aepsg%3Apro&pageMode=PL&t=79841.g.1&cc=US&lc=eng .   That is a rather involved procedure requiring an external DMM making 4-wire resistance measurements on all channels and comparing the results to the 34901A specifications.   You can abbreviate that by making 2-wire resistance measurements with shorting jumpers on all channels.   The results will be very close to the specifications, but aren’t exactly what is specified.
