为8753D配备一个3.5mm校准套件

> {quote：title = peol1写道：} {quote}>嗨，>>我需要为我们的8753D配备一个3.5mm校准套件，我在犹豫是否应该买一个新的（或用过的）85033E（这是
VNA不支持 - 需要手动添加cal coeffs）或尝试从一些知名的二手经销商那里找到一个二手的85033D。
使用一年保修和有效的Keysight cal的二手85033D花多少钱？
还是值得去85033E？
我在某处看到D和E使用相同的cal系数，这是否意味着我可以使用85033E套件使用我们的VNA中预先定义的85033D校准套件进行校准？
购买二手校准套件，特别是3.5毫米，是一件很棒的事情！
我认为您不会找到具有一年保修和Keysight校准的85033D。
获得校准套件的成本非常高，在低端套件上不值得。
我认为我的85052B和85054B的成本是我的VNA校准的3倍。
你可能会发现一个带有保修的校准套件和来自$ random_lab的校准证书，这不值得写上它的论文。
85033D和E非常相似。
我认为E具有定义的短路的电感，但不是D，但是无论如何你都无法将它们输入到8753中，并且它们非常微不足道。
我会自己去找85033E。
如果不出意外，它们更新，所以不太可能被搞砸。
请给我发一封私人电子邮件给drkirkby@kirkbymicrowave.co.uk我可能会对您感兴趣。

How much would be wise to spend on a used 85033D with one year warranty and valid Keysight cal? Or is it worth going for the 85033E? I read somewhere that the D and E uses the same cal coeffs, does that mean that I could calibrate using a 85033E kit using the pre-defined 85033D cal set already in our VNA?

Buying used cal kits, especially 3.5 mm, is a hit and miss affair! 

I don't think you will find an 85033D with a one year warranty and Keysight calibration. The cost of getting cal kits calibrated is very high, and not worthwhile on low end kits. I think my 85052B and 85054B cost about 3x as much to get calibrated as my VNA. 

You might find a cal kit with a warranty and a cal certificate from $random_lab, which is not worth the paper it is written on. 

The 85033D and E are very similar. I think the E has the inductance of the shorts defined, but not the D, but you wont be able to enter them into the 8753 anyway, and they are pretty insignificant. 

I would go for an 85033E myself. If nothing else, they are newer, so less likely to be screwed up. 

Drop me a private email to drkirkby@kirkbymicrowave.co.uk I might have something of interest to you.

您可以从此处下载85033E校准套件文件。
http://na.support.keysight.com/pna/caldefs/stddefs.html?dl=1将其保存到软盘并将其加载到8753D中。

  You can download the 85033E cal kit file from here.   http://na.support.keysight.com/pna/caldefs/stddefs.html?dl=1
Save it to a floppy and load it in your 8753D.

8753数据在这里http://na.support.keysight.com/pna/caldefs/87xx/D5335E.htm但我很确定它与D相同，只是E有电感系数L0，L1，
L2和L3，8753无法使用。
电感值可以在PNA数据http://na.support.keysight.com/pna/caldefs/PNA/85033DE.htm上看到，但请注意该页面上有一些舍入，因此某些值不是太大
准确。

The 8753 data is here

http://na.support.keysight.com/pna/caldefs/87xx/D5335E.htm

But I am pretty sure it is the same as the D, except the E has the inductance coefficients L0, L1, L2 and L3, which the 8753 can't use. 

The inductance values can be seen on the PNA data 

http://na.support.keysight.com/pna/caldefs/PNA/85033DE.htm

but note that there is some rounding on that page, so some of the values are not too accurate.

我在报价中说：保修一年，包括按键校准。
所以我猜它已被检查过......

  In the quote I got it says: one year warranty, keysight calibration included. So I guess it has been checked...
