你好。
我有个问题。 我们需要测量同时具有不同类型连接器的2端口和3端口系统的S参数。 系统的端口将具有1.85,2.4和2.92 mm连接器。 我们将为此目的购买N5224A网络分析仪。 我们还将购买2.4毫米机械校准套件。 我们的设备的参数也将由我们的客户控制,该客户的Agilent N4373C 67 GHz LNA采用1.85mm电缆,Agilent N4694A模块用于校准。 我是否理解正确,我们还需要购买11904S适配器套件(2.4 mm至2.92 mm)然后在使用2.4 mm校准套件进行校准后,我们将能够以某种方式将适配器.A3文件加载到我们的VNA中,它将补偿 测量设备和特定端口上电缆的2.4 mm连接器之间是否存在适配器? 我们的客户是否可以使用他的VNA(E8361C,它是N4373C 67 GHz LNA的一部分)使用N4694A模块进行校准后如果我们给他适配器和.A3文件? 以上来自于谷歌翻译 以下为原文 Hello. I have a question. We will need to measure S-parameters of 2-port and 3-port systems that will have different types of connectors simultaneously. Ports of the system will have 1.85, 2.4 and 2.92 mm connectors. We are going to purchase N5224A network analyzer for this purpose. We are also going to purchase 2.4 mm mechanical calibration kit. Parameters of our devices will also be controlled by our customer, which has Agilent N4373C 67 GHz LNA with 1.85mm cables and Agilent N4694A module for calibration. Do I understand correctly, that we also need to purchase 11904S Adapter Set(2.4 mm to 2.92 mm) And then after performing calibration with 2.4 mm calibration set we will be able to somehow load adapter .A3 file into our VNA and it will compensate the presence of adapter between measured device and 2.4 mm connector of the cable on a particular port? Will our customer be able to do the same with his VNA (E8361C which is the part of N4373C 67 GHz LNA) After performing calibration with N4694A module if we give him adapters and .A3 file? |

嗨,你的理解是正确的。
对于带有1.85 mm连接器的DUT,您可以使用N4694A在1.85 mm电缆上进行校准,并直接测量DUT。 由于2.4 mm连接器与1.85 mm连接器兼容,因此您可以校准和测量与1.85 mm DUT相同的2.4 mm DUT。 由于1.85 mm连接器与2.92 mm连接器不兼容,因此必须使用2.4-2.92 mm适配器连接2.92 mm DUT。 如果您了解2.4-2.92 mm适配器的特性,则可以使用N4694A在1.85 mm电缆上进行校准,在连接适配器的情况下测量2.92 mm DUT,然后使用PNA中的去嵌入功能来移除适配器效果。 要表征2.4-2.92 mm适配器的s2p数据,您需要在带有N4694A的1.85 mm电缆上进行单端口校准,使用2.92 mm校准套件连接适配器进行另一个单端口校准,使用两个校准 设置,您可以使用PNA上的Adapter Characterization宏来获取2.4-2.92 mm适配器的s2p数据。 因此,除了N4694A之外,您还需要一个2.92 mm校准套件用于适配器表征。编辑:ningchen于2014年7月23日上午6:56 以上来自于谷歌翻译 以下为原文 Hi, your understanding is correct. For DUT with 1.85 mm connectors, you can calibrate at the 1.85 mm cable with N4694A and measure the DUT directly. As 2.4 mm connectors are compatible with 1.85 mm connectors, you can calibrate and measure the 2.4 mm DUT same as the 1.85 mm DUT. As the 1.85 mm connector is not compatible with the 2.92 mm connector, you have to use 2.4-2.92 mm adapter to make connection to your 2.92 mm DUT. If you know the characteristics of the 2.4-2.92 mm adapter, you can calibrate at the 1.85 mm cable with N4694A, measure your 2.92 mm DUT with the adapter connected, then use the de-embedding capability in the PNA to remove the adapter effects. To characterize the s2p data of the 2.4-2.92 mm adapter, you need to do a one-port calibration at the 1.85 mm cable with N4694A, do another one-port calibration with the adapter connected using 2.92 mm cal kit, with the two cal sets, you can use the Adapter Characterization macro on the PNA to acquire the s2p data of the 2.4-2.92 mm adapter. So you will also need a 2.92 mm cal kit besides N4694A for adapter characterization. Edited by: ningchen on Jul 23, 2014 6:56 AM |
