因此,我正在考虑将我的旧8510C系统退役并寻找更新,更高档的产品,目前市场上似乎有一堆N5230 VNA,但大多数都是6或9GHz的射频型号,所以我的问题是:确实是安静的
提供任何升级套件来改变让我们说6GHz到20GHz或20GHz到40GHz VNA? 这是否具有成本效益? 那些VNA在准确度方面与8510C相比如何? 8510C具有使用E4418B仪表进行测试端口功率校准的功能,5230是否提供类似的功能? 以上来自于谷歌翻译 以下为原文 So im contemplating sending my old 8510C system into retirement and go for something newer and fancier, there seem to be bunches of N5230 VNA on the market right now but most of them are RF models to 6 or 9GHz , so my question is : does agilent offer any upgrade kits to change lets say a 6GHz into a 20GHz or a 20GHz into a 40GHz VNA ? is this cost effective ? how do those VNA Compare to the 8510C in terms of accuracy ? the 8510C had a function to do a testport power calibration with a E4418B meter, does the 5230 offer a similar function ? |

升级时:不,零件完全不同。
关于功能:我们可以使用PNA完成所有工作。 较新的(具有触摸屏)具有最大的能力。 查看Agilent网站了解复古与固件功能。 例如,N5230A现在仅限于旧固件版本。 以上来自于谷歌翻译 以下为原文 On upgrades: no, the parts are completely different. On features: we can do everything with the PNA. Newer ones (that have touch screens) have the most capability. Check the Agilent website for vintage vs. firmware features. N5230A's are now limitied to old firmware rev's, for example. |

现在我得到了8510C,带有83630B和8517B测试装置,原装系统有一个83651A源,但它很糟糕,修复估计让我畏缩,所以我联系了83630因为主要我们的工作现在无论如何都在26GHz以下!
我想念8510的一个主要特点是能够测量放大器的稳定系数,我们有一个R + S ZVB8作为射频分析仪提供这种能力,但我不确定PNA是否可以做到这一点,我们有PNA 在诺基亚西门子,我正在寻找风向标! 以上来自于谷歌翻译 以下为原文 right now i got a 8510C with a 83630B and a 8517B testset , original the system had a 83651A source but it was bad and the repair estimate made me crinch so i hooked up the 83630 since mainly our work is below 26GHz right now anyway ! one of the main features i miss on the 8510 is the ability to measure the stability factor of a amplifier, we have a R+S ZVB8 as RF analyzer which offers this capability but im not sure if the PNA can do it , we had PNA at Nokia Siemens and i was looking for this in vane ! |

kasonandy 发表于 2019-1-9 15:29 PNA当然可以测量放大器稳定系数(K)。 该功能位于PNA的公式编辑器内(在Marker / Analysis-> Analysis-> Equation Editor菜单下)!https://dl.dropboxusercontent.com/u/87949221/EquationEditor.png! 以上来自于谷歌翻译 以下为原文 PNA's can certainly measure Amplifier Stability Factor (K). that feature is inside the equation editor for the PNA (under Marker/Analysis->Analysis->Equation Editor menu) !https://dl.dropboxusercontent.com/u/87949221/EquationEditor.png! |

在实践中,PNA都是相同或更好的。
根据规格,这取决于您使用的是什么版本的8510; 最好的版本(8360合成器和8515测试装置)非常好,您必须使用新PNA的计量选项才能获得比8510更好的规格。但除非您正在进行计量工作,否则您将永远不会看到 区别。 以上来自于谷歌翻译 以下为原文 In practice, the PNA's are all the same or better. By spec, it depends on what version of 8510 you are using; the best version (wtih an 8360 synth and and 8515 test set) was very good, you have to use the metrology option of the new PNA to have a better spec than the 8510. But unless you are doing metrology work, you will never see the difference. |
