如果试图测量负载，则在N9912A上没有完成QuickCal

我在N9912A上遇到QuickCal问题。
当我拿到仪器时固件是5.x，我相信在这一点上VNA至少在某种程度上起作用。
在我将固件升级到最新版本（A.07.32 build 2014-03-1.16：32）之前，我并没有使用它，但是自升级以来，事情似乎已经变得很糟糕。
我为照片的质量道歉 - 光线在这里快速消失。
1）选择QuickCal时，我可以选择测量负载或跳过负载（参见第一张照片）。
这是我的预期。
2）如果我跳过负载（第二张照片），仪器将报告“执行校准... 100％”，然后一行中最右边的6个键显示“完成”。
按下似乎导致校准，但我不相信它运作良好 - 但这是另一回事。
我在这篇文章中报告的问题是下一点。
3）如果不是在QuickCal期间跳过负载，而是测量它，仪器需要更长的时间来测量开路和负载。
在测量负载结束时，它显示“执行校准... 100％”但是任何按钮都没有文本。
当我跳过负载时，有*不*工作“完成”。
从本质上讲，如果测量负载，我认为QuickCal根本不工作。
执行QuickCal并测量负载后，唯一似乎响应的按钮是ESC键。
如果我然后按ESC，然后按CAL，我可以看到错误纠正已关闭。
我不相信QuickCal已经完成。
这是固件错误，硬件错误，还是我的脑细胞无法正常工作？

  I have a problem with QuickCal on the N9912A. When I got the instrument the firmware was at 5.x, and I believe at that point the VNA in this was working at least to some extent. I did not use it much before I upgraded the firmware to the latest (A.07.32 build 2014-03-1.16:32), but since upgrading, things seem to have gone pear shaped. I apologize for the quality of the photos - light was fading fast here.  

1) When selecting QuickCal, I get the choice to measure the load or skip the load (see first photo). This is what I expected.  

2) If I skip the load (second photo), the instrument reports  

"Performing calibration... 100%"

and then the right-most of the 6 keys in a line shows "Finish" above it. Pressing that appears to result in a calibration, though I am not convinced it has worked well - but that is another matter. The problem I am reporting in this post is in the next point.  

3) If instead of skipping the load during QuickCal, I measure it, the instrument takes a bit longer as it measure both the open and load. At the end of measuring the load it says  

"Performing calibration... 100%"

But there is no text by any of the buttons. There is *not* the work "Finish" as there was when I skipped the load.  

Essentially, I don't think the QuickCal is working at all if the load is measured. The only button that seems responsive after doing a QuickCal and measuring the load is the ESC key. If I then press ESC, followed by CAL, I can see the error correction is off. I do not believe the QuickCal has completed.  

Is this a firmware bug, hardware bug, or my brain cells not working properly?  

Dave
