E4402B跟踪发生器故障

经过一番调查后，我发现了失败的原因。
TG的RF输出具有DC限制器，旨在防止ESD，DC瞬变和过多的RF功率，看起来该设备已损坏。
它类似于：1GG5-8205旁路它产生预期的RF输出，所以我认为我找到了一个简单的解决方案。
不幸的是，1GG5-4202很难找到 - 即使是数据表也无处可寻。
任何人都有这方面的任何信息，或者有一些使用/破坏的设备与1GG5-4202谁愿意帮助我们？
请参阅中国供应网站下面的零件图片。
我在中国发现了一些有一些可用但不确定对这些供应商有多信任的地方。

  So after some more sleuthing, I figured out what has failed. The RF output of the TG has a DC limiter which is designed to protect against ESD, DC transients and excess RF power and it looks like this device is damaged. It is similar to this:  1GG5-8205 

Bypassing it produces the expected RF output so I thought I found an easy solution. Unfortunately the 1GG5-4202 is a difficult part to find - even a datasheet is nowhere to be found. 

Anyone have any info on this part or have some used/broken equipment with the 1GG5-4202 that are willing to help us out? See a picture below of the part from a Chinese supply site. 

I have found a few places in China that have some available but not sure how much to trust some of these suppliers.

嗨迈克 - 我们不支持此级别的故障排除。
安捷伦不支持元件级维修，只支持组件级维修，因此，我建议必须更换整个BITG微电路。
问候 -

  Hi Mike -

We do not support troubleshooting to this level.  

Agilent does not support component level repair, only assembly level repair, therefore, I suggest the entire BITG microcircuit has to be changed.
