可以使用N,APC7或3.5 mm套件来表征7-16 DIN校准套件吗?

在我看来,安捷伦以三种方式在R& S + Anritsu上得分。
a)对现有设备提供更好的官方支持。
尽管校准设备是当前型号,但可以从Anritsu网站购买http://configure.us.anritsu.com/catalog/i/2000-1619-R http://configure.us.anritsu.com/catalog
/ i / 2000-1618-RI看不到任何文档。
b)对不支持的设备提供良好的支持,但当然不是新设备的水平。
c)更好地支持完全独立于安捷伦。
HP / Agilent Yahoo小组非常活跃,每天有几个帖子,而R& S小组每周都有一个帖子。
Anritsu + Sitemaster +组也基本上死了。
>不幸的是,我不知道怎么做......乔尔可能是你唯一的希望。
他的书中有关于使用TDR选项执行此操作的内容。
我的8720D有选项010,但我仍然对这样做的方式感到困惑。
我相信TDR选项的时间分辨率约为2 / f,其中f是频率跨度。
8720D覆盖50 MHz至20.05 GHz,因此范围为20 GHz。
这意味着分辨率约为100 ps,这远远不够好。
鉴于7-16只能达到8 GHz左右,它甚至会变得更糟。
我可以非常自信的唯一方法是使用另一个相同的Anritsu套件,切割它,测量尺寸并使用3D EM模拟器。
虽然这是一个昂贵的选择!
但它可能会奏效。
Ken和Joel都有关于使用EM模拟器的论文。
我还想过制造零偏移延迟的短路,然后使用它来至少确定Anritsu短路的偏移延迟。
当然,我可能很幸运,Anritsu告诉我,但我没有屏住呼吸。

Agilent scores over both R&S + Anritsu in three ways in my opinion. 

a) Better official support on current equipment. Despite the fact the calibration devices are current models one can buy from the Anritsu site

http://configure.us.anritsu.com/catalog/i/2000-1619-R
http://configure.us.anritsu.com/catalog/i/2000-1618-R

I can't see any documentation. 

b) Good support on unsupported equipment, though not to the level of new equipment of course.

c) Better support totally independent of Agilent. The HP/Agilent Yahoo group is very active, with several posts per day, vs the R&S group where there is a post every week or two. The Anritsu +Sitemaster+ group is basically dead too. 

> Unfortunately, I have no idea how to do this...Joel may be your only hope here.

There is something in his book about using the TDR option to do this. My 8720D has option 010, but I'm still very confused about the way to do it. I believe the temporal resolution of the TDR option is about 2/f, where f is the frequency span. The 8720D covers from 50 MHz to 20.05 GHz, so a range of 20 GHz. That implies a resolution of around 100 ps, which is nowhere near good enough. And given a 7-16 is only rated to 8 GHz or so, it gets even worst. 

The only way I can be pretty confident would work is taking another identical Anritsu kit, cutting it up, measuring the dimensions and using a 3D EM simulator. It is a bit of an expensive option though! But it would probably work. There are papers from both Ken and Joel about using EM simulators for this. 

I also thought of fabricating a short with zero offset delay, then using that to at least determine the offset delay of the Anritsu shorts. 

Of course, I might be lucky and Anritsu tell me, but I am not holding my breath.

他们给我发了7-16开/短/负载的+规格+,但它的信息量不大。
我找不到像安捷伦单一套件那样的参数。
他们写道:“您所要求的校准系数通常不需要,因为这些设备仅供现场使用,但我会向工厂询问他们是否有任何数据。”
无论如何,我们将看到会发生什么。

To be fair, I did get a respose from Anritsu a few hours asking them. They sent me the +specifications+ of their 7-16 open/short/load, but it is not very informative. I can't find the parameters like I could for an Agilent one kit. They wrote 

"The calibration coefficients which you have requested are not normally required as these devices are for field use but I will ask our factory if they have any data for you."

Anyway, we shall see what happens.

我从Anritsu获得了参数,而且非常有趣。
旧的已停产的4 GHz Anritsu型号与当前的Agilent 85038A 7-16校准套件具有基本相同的开路和短路参数。
*所有电容和电感系数相同。
* Anritsu从未给我一个损失数字,而安捷伦为85038A提供0.63 G Ohm / s *如果将过时的Anritsu设备的偏移长度(20 mm)转换为时间(假设空气中的光速为2.99705 x 10)
^ 8 m / s),Anritsu的偏移延迟为66.7323 ps,这非常接近Agilent 85038A套件的偏移延迟(66.73399 ps)。
人们可以原谅开口和短裤基本上是相同的设计!
我想知道Maury Microwave或者其他人是否为安捷伦和Anritsu制作了它们。
目前的6 GHz Anritsu设备明显不同,男性和女性设备不同。
如果其他人想要使用设计用于Anritsu SiteMaster的“T形”校准设备之一,这里是Anritsu给我的参数。
正如我所说,前两个设备似乎非常接近Agilent 7-16套件。
* 2000-767-R(公7-16,4 GHz,已过时)*开偏移= 20 mm短偏移= 20 mm C0 = 32 C1 = 100 C2 = -50 C3 = 100 L0,L1,L2,L3 = 0

  I got the parameters from Anritsu and something is quite interesting. 

The old discontinued 4 GHz Anritsu models have essentially the same parameters for the opens and shorts as the current Agilent 85038A 7-16 Calibration Kit. 

* All capacitance and inductance coefficients are identical. 
* Anritsu never gave me a loss figure, whereas Agilent quote 0.63 G Ohm/s for the 85038A 
* If one converts the offset length (20 mm) of the obsolete Anritsu devices to time (assuming a velocity of light in air of 2.99705 x 10^8 m/s), Anritsu's offset delay is 66.7323 ps, which is pretty damm close to the offset delay of the Agilent 85038A kit (66.73399 ps). 

One could be excused for thinking the opens and shorts are basically of the same design! I wonder if Maury Microwave or someone like that made them for both Agilent and Anritsu. The current 6 GHz Anritsu devices are significantly different, with male and female devices being different. 

In the event anyone else wants to use one of those "T-shaped" calibration devices which are designed for use with an Anritsu SiteMaster, here are the parameters given to me by Anritsu. As I say, the first two devices seem remarkably close to the Agilent 7-16 kit. 

*2000-767-R (male 7-16, 4 GHz, obsolete)*
Open Offset = 20 mm
Short Offset = 20 mm
C0 = 32
C1 = 100
C2 = -50
C3 = 100
L0, L1, L2, L3 = 0

*2000-768-R: (female 7-16, 4 GHz, obsolete)*
Open Offset = 20 mm
Short Offset = 20 mm
C0 = 32
C1 = 100
C2 = -50
C3 = 100
L0, L1, L2, L3 = 0

*2000-1618-R (male 7-16, 6 GHz, current model)*
Open Offset = 16.9mm
Short Offset =19.7mm
C0 = 182
C1 = 8
C2 = 145
C3 = 46
L0, L1, L2, L3 = 0
 
*2000-1619-R (female 7-16, 6 GHz, current model)*
Open Offset = 26.2mm
Short Offset = 29 mm
C0 = 185
C1 =23
C2 = -184
C3 = 104
L0, L1, L2, L3 = 0
