如果8720D具有新的CPU板，并采用最新的固件（7.74），那么该仪器与8720ES有何不同？
有些8720D配备了新的CPU板，还是仅作为升级版提供？ 感兴趣的是，是否有人知道8720D是否在英国校准过，还是会被送到英国以外的安捷伦实验室？ 我的下个月将到期。 值得庆幸的是，成本并不是太高，尽管8720D的成本略高于8720ES。 戴夫 以上来自于谷歌翻译 以下为原文 If an 8720D has the new CPU board, and so takes the latest firmware (7.74), how would that instrument differ from an 8720ES? Did some 8720Ds ship with that new CPU board, or was it only available as an upgrade? As a matter of interest, does anyone know if an 8720D gets calibrated in the UK, or would it be sent to an Agilent lab outside the UK? Mine is is due for cal next month. Thankfully the cost is not too high, though it is slightly higher on an 8720D than an 8720ES. Dave

我记得在12或13年前通过电子邮件回答了8720ES和8720D之间的差异问题和某人的新CPU，但当时我更容易得到确切的答案。
Dr_joel可能比我记得更好，但我的回忆是（当然两个方框都有相同的选项）大部分只是前面板上的硬键/软键菜单中的一些差异，可能是硬件中使用的一些不同的部分 在所有后面板外围I / O连接器方面，相应的内部测试装置也可以是至少一个差异。 我想，对于8720D来说，新的CPU只是一个升级而且我们没有随身携带任何D，但我对此的记忆也有点模糊。 关于你的8720D最终是否会在英国进行校准，我会向我们的服务/支持人员提一个问题，看看他们是否可以回答这个问题。 以上来自于谷歌翻译 以下为原文 I recall answering the question of differences between 8720ES and 8720D with new CPU for someone via email about 12 or 13 years ago, but the exact answer was more readily available to me at that time. Dr_joel might recall better than I, but my recollection is that (given both boxes having same options of course) for the most part it was just a few differences in hardkeys/softkey menus on the front panel, perhaps some different parts used in the hardware of the respective internal testsets, and might also be at least one difference as far as all the rear-panel peripheral I/O connectors are concerned. I'm thinking that for the 8720D the new CPU was just an upgrade and that we didn't ship any D's with it, but my memory on that is also a tad fuzzy. About whether your 8720D would end up getting calibrated within the UK, I'll mention that question to one of our service/support folks to see if they can answer that. |

谢谢bhokkan和Javil。 如果乔尔确实对8720D / 8720ES的差异有所了解，我有兴趣听听他们，如果他对古董的记忆没有失败的话。 很高兴听到8720D可以在英国进行校准。 在运输过程中损坏的风险较小。 我希望VNA没有任何问题。 我去年从美国经销商那里买了它。 它是由美国的“Techmaster Electronics Inc”校准的。我对那个校准实验室有点怀疑，原因是我要把它放到另一个线程中。 无论如何，对我来说这是一个“毫无疑问”。 当我对VNA进行校准时，我希望安捷伦能够做到这一点，而不是一些可能为我节省几磅的第三方，但我对他们完成这项工作的能力没有信心。 戴夫 以上来自于谷歌翻译 以下为原文 Thanks bhokkan and Javil. If Joel does know any more about the 8720D / 8720ES differences, I'd be interested to hear them, if his memory of the antiques has not failed . It's good to hear the 8720D can be calibrated in the UK. There's less risk of damage in transit. I'm hoping there is nothing wrong with the VNA. I bought it last year from the USA dealer. It was calibrated by "Techmaster Electronics Inc" in the USA.. I'm a bit suspicious of that cal lab, for reasons I'm going to put in another thread. Anyway, for me it is a "no-brainer". When I get my VNA calibrated, I want Agilent to do it, not some third party that might save me a few pounds, but I am not confident of their ability to do the job. Dave |
