我在4端口ENA系列分析仪上遇到了部分校准问题。
如果我完成以下场景:场景1 ---------------- - 执行4端口校准,但在校准的反射部分出错,虽然Thru正确连接
。
- 执行部分校准,正确地重新进行反射(打开/短路/加载)场景2 --------------- - 执行4端口校准,但在通过时出错
虽然反射是正确连接的一部分。
- 执行部分校准,正确地重新执行直通电话在方案1中,最终校准总是不好,但在方案2中,这很好,为什么会这样?
在正确校准之前,似乎总是必须执行好反射校准。

I've been having an issue with the Par
tial Calibration on the 4-port ENA series analyzer.
If I complete the following scenarios:
Scenario 1
----------------
- Perform a 4-port cal but make a mistake on the reflection part of the cal, the Thru is connected correctly though.
- Perform a partial cal, re-doing the reflection (Open/Short/Load) correctly
Scenario 2
---------------
- Perform a 4-port cal but make a mistake on the thru part of the cal, the Reflection is connected correctly though.
- Perform a partial cal, re-doing the Thru cals correctly
In scenario 1, the final calibration is always bad, but in scenario 2 it is good Why is this?
It seems like a good Reflection calibration always has to have been performed, before a Thru cal can be correct.
