应采取哪些措施来保护HP8753网络分析仪免受ESD的损坏？

以下是PNA帮助文件中的官方消息：http：//na.tm.agilent.com/pna/help/latest/Tutorials/esd.htm如果您真的想保护您的投资，请阅读Connector Care上的这一点：

我肯定不知道，所以请自担风险。
但我认为APC7连接器上的低值衰减器可以有效地使VNA免受测试端口静电损坏。
1 dB衰减器将导致动态范围的减少可忽略不计，并且原始源和负载匹配的改善可忽略不计。
但是，由于它会在测试端口上产生小于450欧姆的电阻，我原以为它会保护设备的最静态敏感性。
在静电的情况下，450欧姆就像一个短暂的。
两次我因闪电而损坏了电子设备。
在第一个例子中，我的ADSL现代版被破坏，几台计算机的以太网端口和连接到它的打印机。
一台甚至没有插入主电源的计算机的以太网端口损坏，因此我确信损坏是由架空电话线中的电流和*电源线引起的。
我的房屋保险支付所有新电脑，现代和打印机。
第二次，我的ADSL调制解调器被破坏了，但没有别的，所以我从未提出保险索赔。
我宁愿怀疑8753在主电源或GPIB端口上比50欧姆测试端口更容易损坏。
也许Dr_Joel有一些评论，因为他参与了8753的设计.Dave.Edited：drkirkby于2014年4月15日下午5:06

  I don't know this for sure, so use at your own risk. 

But I would have thought a low value attenuator on the APC7 connectors would effectively make the VNA immune to damage by static at the test ports. A 1 dB attenuator would result in a negligible reduction in dynamic range and a negligible improvement in raw source and load match. However since it would put a resistance of less than 450 Ohms across the test ports, I would have thought it would have protected the most static sensitive of device. 450 Ohms is like a short in the context of static.

Twice I have suffered damage to electronic equipment due to lightening. In the first instance my ADSL modern got destroyed and the ethernet ports of several computers and a printer connected to it. One computer which was not even plugged into the mains electricity got its ethernet port damaged so I am convinced the damage was caused by current being induced in the overhead telephone cables and *not* the power lines. My house insurance paid for all new computers,  a modern and a printer.  

On a second occasion my ADSL modem got destroyed,  but nothing else, so I never made an insurance claim.  

I rather suspect an 8753 is far more likely to get damaged on the mains power or GPIB ports than the 50 Ohm test ports.  

Maybe Dr_Joel has some comments as he was involved in the design of the 8753.



Dave.
