旧的PNA-L（N5230A 1.1Ghz CPU）不支持短校准（4个端口的7步校准）方法。
我预计固件（A.07.50.67）将不会更新，因为该设备已停产数年。 我只是想知道安捷伦是否可以准备可以在旧PNA-L上运行的校准宏，它将支持七步手动校准。 现有的手动校准方法很长。 以上来自于谷歌翻译 以下为原文 The old PNA-L (N5230A 1.1Ghz CPU) do not support the short calibration (7 step cal for four ports) method. I do not expect that the firmware (A.07.50.67) will be updated as the unit is out of production for several years. I just wonder if Agilent could prepare calibration macro that could run on old PNA-L that will support seven steps manual calibration. The existing manual calibration method is very long.

你能澄清你的七个步骤吗？
我知道机械可以有6步，Ecal可以有3步，但我不确定你在七步的位置（除非你指的是导向功率校准）？ 以上来自于谷歌翻译 以下为原文 Can you clarify the seven steps you mean? I know there can be a 6 step with mechanical, and a 3 step with Ecal, but I'm not sure where you ge the seven steps (unless you mean guided power calibration as well)? |

嗨Joel Heppy新年!!! 好吧，我在PNA-X上检查它，它显示了2个端口机械校准的7个步骤：端口1：打开（1），短（2），负载（3），端口2打开（4），短（5）， 加载（6），并通过端口1和端口1 港口2（7）。 我应该更具体一点：旧PNA-L机械校准的步骤数为：4端口27步3端口26步2端口17步1端口3步PNA-X上机械校准的步数为： 4端口15步骤3端口11步骤2端口7步骤1端口3步骤简单的步骤是特别方便的，您需要在不同的连接器类型之间进行校准，真正的生命安全真的很高兴有这个宏用于较低的数字 旧PNA-L上的步骤校准 以上来自于谷歌翻译 以下为原文 Hi Joel Heppy New Year!!! Well I check that on PNA-X and it showing like 7 steps for 2 port mechanical cal: Port 1: Open(1) , Short(2), Load(3), Port 2 Open(4) , Short(5), Load(6), and thru between Port 1 & Port 2(7). I really should be more specific: The number of steps for mechanical calibration on old PNA-L are: 4 Ports 27 steps 3 Ports 26 steps 2 Ports 17 steps 1 Port 3 steps The number of steps for mechanical calibration on PNA-X are: 4 Ports 15 steps 3 Ports 11 steps 2 Ports 7 steps 1 Port 3 steps That short number of steps are specially convenient what you need to calibrate between different connector type, Truly a life safe It really will be nice to have that macro for lower number of calibration of steps on old PNA-L. |

e08506806 发表于 2019-4-16 20:45 我相信PNA-L和PNA-X之间的差异是通过方法。 在PNA-X上，默认的直通方法是Unknown Thru，因此是7步2端口cal。 在PNA-L上，由于接收器架构，无法实现1层Unknown Thru cal，因此默认情况下它会执行适配器删除。 如果你的PNA-L有一个全局增量匹配cal（第一层），你将可以做一个7步未知通过cal作为第二层cal。 Global Delta Match cal是在测试端口执行的宽带第一层校准，无需像您为日常测量需求执行的常规用户那样频繁重复。 以上来自于谷歌翻译 以下为原文 I believe the difference between the PNA-L and PNA-X is the thru method. on the PNA-X the default thru method is the Unknown Thru and hence the 7-step 2-port cal. on the PNA-L, due to the receiver architecture, a 1-tier Unknown Thru cal is not possible and therefore it performs an adapter removal by default. if your PNA-L has a global delta match cal (1st tier) however, you will be able to do a 7-step unknown thru cal as a 2nd tier cal. the Global Delta Match cal is a broadband 1st tier calibration performed at the test ports and does not need to be repeated as often as the normal user cals you perform for your daily measurement needs. |

Topcbpcba 发表于 2019-4-16 20:59 除了daras评论之外，您还可以使用PNA-L菜单栏顶部的下拉菜单在PNA-L上执行您自己的全局增量匹配校准：响应：校准并在那里某处是GDM（不在 仪器现在，所以不能说）。 由于Rx硬件配置的变化，PNA-L是L'ish（成本更低），这节省了资金，但需要预先确定用作源的端口匹配与端口匹配之间的差异 用作负载。 这是“delta-match”术语的特征，并且不会随着电缆/连接器/固定装置而改变，因此可以表征一次并用于其他cals。 但是一旦将其描述为第一层，则可以使用7步cals。 但等等，有更多：如果你使用“修改校准”复选框，在某些情况下你也可以使用QSOLT校准（如果你有一个定义的通过），并允许2端口校准只有4步（OSLT）。 一个4端口校准，有6个步骤（端口1上的OSL，1-2到1-3，到1-3）。 如果您的cal是不可插入的（例如每个端口上的f-f），您可以表征直至1次，将其添加到cal-kit，并将其用于定义的直通卡！ 以上来自于谷歌翻译 以下为原文 Further to daras comment, you can perform your own Global Delta Match cal on the PNA-L using the pull-down menu on the top of the PNA-L menu-bar: Response:Cal and under there somewhere is GDM (Not at an instrument now, so can't say). The PNA-L is L'ish (lower cost) due to changes in the Rx hardware configuration which saves money but makes requires a pre-characterization of the difference between the Match of a port used as a source, and the match of a port used as a load. This is the "delta-match" term which is characterized, and doesn't change with cables/connectors/fixtures so can be characterized one time and used for other cals. But once that is characterized as a first tier, then the 7-step cals can be used. BUT WAIT, there's MORE: If you use the "modify cal" check box, in some cases you can also use the QSOLT cal (if you have a defined thru) and that allows a 2 port cal with only 4 steps (OSLT). And a 4 port cal with 6 steps (OSL on port 1, thru 1-2, thru 1-3, thru 1-4). If your cal is non-insertable (such as f-f on each port) you can characterize a thru 1 time, add it to the cal-kit, and use it for the defined thru cal! |
