怎么加快N5242A PNA的CW时间测量

首先，我们正在努力解决多重问题。
听起来像你已经设置了一些完整的双端口校正跟踪。
为了进行有效的测量，它必须扫描*两个*方向。
如果你真的需要完整的2端口校正，这是正常的，通常是不可避免的。
但是，很可能你没有。
你可能想重新考虑一下。
简单的响应或增强响应是否足够？
这两个都可以消除额外的20秒。
扫描结束处理通常只需要几毫秒，因此您肯定会看到反向扫描效果。
还有，如果您使用1kHz IFBW（或更低），则PNA会自动进入步进扫描模式。

  First, we are trying to solve the multiple post issue.

It sounds to me like you have setup some trace with a full two-port correction.  In order to make a valid measurement, it has to sweep in *both* directions.  This is normal and generally unavoidable if you *really* need the full 2-port correction.  However, most likely you do not.  You may want to rethink this.  Would a simple Response or Enhanced Response cal suffice?  Both of these would eliminate the extra 20 seconds.

End of sweep processing normally only takes a few milliseconds, so you are definitely seeing the reverse sweep effects.

And FYI, if you are using 1kHz IFBW (or less), then the PNA is automatically put in Stepped Sweep mode.

phoenixblitzer进入“扫描设置”并选择“点扫描”。
在这种情况下，即使在矢量校准下，它也会在进入下一个点之前测量每个点的正向和反向。
这个功能总是让我想起旧的8753网络分析仪和切碎的mod。

Go to "sweep setup" and choose " point sweep". In such case even under vector calibrtaion it will measure forward and revers for each point before going to next point.

That funtion always remind me the old 8753 Network Analyzer and the chopped mod.
