SMA与3.5mm E5071C校准最可靠的配置是什么?

嗨,我对使用连接器只有一个疑问,如果Ecal和电缆(公SMA)与它们之间的3.5mm(F)-SMA(F)适配器配合,它是否会影响校准过程?
是否有N4433A Ecal带有母SMA连接器?
什么是这个过程最可靠的配置?
我的配置是:E5071C(3.5mm MALE) - > 3.5mm(F)到SMA(F)适配器 - > 18GHz SMA(M)-SMA(M)电缆 - >然后带有SMA F连接器的ECal这个配置正在进行
上班?

  Hi
i just have one doubt about using connectors,

Does it affects in the calibration process if the Ecal and the cables(male SMA) are mated with a 3.5mm(F)-SMA(F) adapter between them?

Is there any N4433A Ecal with Female SMA Connector?

Whats the most reliable configuration for this process?

my configuration would be:

E5071C (3.5mm MALE) -> 3.5mm (F) to SMA (F) adapter -> 18GHz SMA(M)-SMA(M) cable -> Then the ECal with SMA F Connectors

Is this configuration going to work?

Thank you for your answers

regards

是的,N4433A Ecal可选配3.5 mm母端口,实际上所有端口连接器类型都可供选择:N4433A-010四个3.5 mm母头连接器N4433A-101端口A连接器为3.5 mm母头N4433A-102端口A连接器为3.5 mm公头N4433A-
201端子B连接器为3.5 mm母头N4433A-202端子B连接器为3.5 mm公头N4433A-301端口C连接器为3.5 mm母头N4433A-302端口C连接器为3.5 mm公头N4433A-401端口D连接器为3.5 mm母头N4433A-402端子D连接器为3.5
mm公头最常见的配置是:ENA(带3.5 mm公连接器)+ 3.5 mm或SMA电缆(3.5 mm母头到3.5 mm公头)+ DUT带所有端口3.5 mm母头连接器。
Ecal在所有端口上也是3.5毫米连接器。
如果您的Ecal带有公母连接器但您的设备都是3.5 mm母连接器,则可以使用Unknown Thru calibraiton方法来补偿3.5 mm母母连接器的效果。
在Unknown Thru Cal中,您使用Ecal母端口在端口1上执行单端口校准,然后在端口2上使用Ecal母端口执行单端口校准,然后使用端口1进行Thru(3.5 mm ff适配器)校准
2. Thru只需要是倒数(S12 = S21),并且可以计算所有12个误差项。
您可以参考ENA帮助以了解如何在ENA中使用Unknown Thru cal。编辑:ningchen于2014年7月17日晚上8:00

  Yes, the N4433A Ecal has the option of 3.5 mm female ports, actually all the port connector type are options:

N4433A-010     Four 3.5 mm female connectors
N4433A-101     Port A connector is 3.5 mm female
N4433A-102     Port A connector is 3.5 mm male
N4433A-201     Port B connector is 3.5 mm female
N4433A-202     Port B connector is 3.5 mm male
N4433A-301     Port C connector is 3.5 mm female
N4433A-302     Port C connector is 3.5 mm male
N4433A-401     Port D connector is 3.5 mm female
N4433A-402     Port D connector is 3.5 mm male

the most common configuration is: ENA (with 3.5 mm male connectors) + 3.5 mm or SMA cables (3.5 mm female to 3.5 mm male) + DUT with all ports 3.5 mm female connectors. The Ecal is also 3.5 mm connectors on all ports.

If you have a Ecal with male and female connectors but your device is all 3.5 mm female connectors, you can use the Unknown Thru calibraiton method to compensate for the effects of the 3.5 mm female-female adapter. In Unknown Thru Cal, you do a one-port cal on port 1 with the Ecal female port, then a one-port cal on port 2 with the Ecal female port, then a Thru (3.5 mm f-f adapter) calibration with port 1 and 2. The Thru only needs to be reciprocal (S12 = S21), and all the 12 error terms can be calculated.

You can refer to the ENA help to know how to use Unknown Thru cal in ENA.
