无法读取磁盘到VNA的系数

> {quote：title = ChrisRAN写道：} {quote}>我使用的是带有8722ES VNA的85056A 2.4mm校准套件，但校准套件最初用于8510，我无法从磁盘读取系数
进入VNA。
8722看到磁盘上的文件但无法读取它。
有没有办法访问校准文件（例如转换器），以便我可以手动加载它们？
谢谢。
85056A的系数是否不在8722ES的固件中？
根据http://na.support.keysight.com/pna/caldefs/stddefs.html他们是。
假设它们在固件中，您只需选择它们即可。
我有一个8720D，这是8722ES的旧/低频版本。
但我的8720D拥有最新的CPU，这意味着它运行与8720ES相同的固件。
我查看了8720D的固件，看到列出的2.4毫米85056。
我怀疑在8722上甚至可能默认使用该套件，但在我的8720D上它默认为85052 3.5 mm套件。
所以从本质上讲，我认为你根本不需要担心任何磁盘。
系数应该在您的固件中。

> I'm using an 85056A 2.4mm cal kit with an 8722ES VNA, but the cal kit was originally for an 8510 and I'm unable to read the coefficients from the disk into the VNA.  The 8722 sees the file on the disk but cannot read it.  Is there a way of accessing the cal files (converter for instance) so that I can manually load them?  Thanks.

Are the coefficients for the 85056A not in the firmware of the 8722ES? According to 

http://na.support.keysight.com/pna/caldefs/stddefs.html

they are. Assuming they are in the firmware, you just need to select them. 

I have an 8720D, which is the older / lower frequency version of the 8722ES. But my 8720D has the latest CPU, which means it runs the same firmware as an 8720ES would. I looked in the firmware of my 8720D, and see the 2.4 mm 85056 listed. I suspect it probably even defaults to that kit on an 8722, but on my 8720D it defaults to the 85052 3.5 mm kit.

So in essence, I don't think you need to worry about any disk at all. The coefficients should be in your firmware.

大卫嗨，谢谢你的快速回复。
你是对的，8722在它的固件中预设了校准系数。
也许我已经过度复杂了，但我会认为每个套件的偏移量是不同的，因此我必须修改不同85056A的存储值？
也许我错了，他们的制造/宽容都在特定的范围内？
较旧的8510没有固件功能，因此磁盘，所以我一直在尝试阅读它们来比较它们。
听起来我可能不需要这样做，所以再次感谢。
干杯，克里斯。

  Hi David,

thanks for the very quick reply.  You're right that the 8722 has preset cal coefficients in it's firmware.  Maybe I'm over complicating things, but I would have thought that the offsets for each kit were different and hence I'd have to modify the stored values for a different 85056A?  Maybe I'm wrong and they're manufactured/toleranced to all be in a specific range?

The older 8510 didn't have the firmware feature hence the disk, so I'd been trying to read them back to compare them.

Sounds like I might not need to do that, so thanks again.

Cheers,

Chris.

？

正如Dave指出的那样，后者是相同型号的所有套件的系数相同。

It is the latter, as Dave was indicating, the coefficients are the same for all kits of the same model number.
