有75欧姆分析仪E5061B内部框图吗

只有Keysight的某个人才能确认。
但基于我见过的其他75欧姆分析仪，大多数内部都是50欧姆，但桥接器是75欧姆。
使用内部50-> 75欧姆焊盘会对性能造成相当大的影响，所以我怀疑他们会这样做。
但是你需要让Keysight的某个人给你一个明确的答案。

Only someone from Keysight will be able to confirm it for sure. But based on other 75 Ohm analyzers I have seen, most of the internals are 50 Ohms, but the bridge is 75 Ohms. The use of internal 50->75 Ohm pads would compromise the performance quite a bit, so I doubt they would do that. 

But you will need to get someone from Keysight to give you a definitive answer.
