大家好,我拥有8753D opt 011(和000,006和010)和85047A TS几年。
我在普通的8753D(选择1D5,002,006和010)上得到了很多,这将让我卖掉opt 11 VNA / TS。 我开始比较两者,并注意到opt 11 vna的固件版本为07.14 1998年4月29日。普通版本是05.40版本:1996年3月27日。我对版本号的巨大差异感到非常惊讶。 经过一番搜索,我发现版本7.14需要选项000,这是CPU升级。 有趣的是,我看到我的opt 11 vna有这个升级。 我有兴趣尝试尽可能地升级普通vna。 然后出售opt 11仪器。 我可以(并且会谨慎)进行一些交换以允许我升级到最新的固件吗? 我是否可以尝试将CPU升级到普通VNA? 固件是否附带它(部分cpu移动)? 获得未升级的cpu /旧固件的VNA会发生什么? 基本上,根据我在这里的内容,我可以保留简单的VNA并使其成为两者中的“最佳”吗? 然后出售另一个,较小的vna / ts。 如果感兴趣,序列号是:opt 11 vna:US39172796 plain vna:3410A07172(为什么序列号中没有美国?)期待有关这种情况的建议。 谢谢,Eugene W2HX ---看起来他们解决了Apache Failure问题编辑:w2hx于2014年9月4日上午6:13 以上来自于谷歌翻译 以下为原文 Hello all, I have owned an 8753D opt 011 (and 000, 006, and 010) with an 85047A TS for a few years. I just got a great deal on a plain 8753D (opt 1D5, 002, 006, and 010) that will let me sell the opt 11 VNA/TS. I began to compare the two and noticed that the opt 11 vna had firmware version 07.14 April 29, 1998. The plain one is version 05.40: MAR 27, 1996. I was very surprised at the large difference in version numbers. After some searching, I found that version 7.14 required option 000 which is a CPU upgrade. Interestingly, I saw that my opt 11 vna has this upgrade. I am interested in trying to upgrade the plain vna as much as I can. Then sell the opt 11 instrument. Can I (and would it be prudent) to do some swapping to allow me to upgrade to the latest firmware? Can I/should I attempt to move the CPU upgrade to the plain VNA? Will the firmware come with it (part of the cpu move)? What will happen to the VNA that gets the un-upgraded cpu/old firmware? Basically, based on what I have here, can I keep the plain VNA and make it the "best" of both of them? Then sell the other, lesser, vna/ts. In case this is of interest, serial numbers are: opt 11 vna:US39172796 plain vna:3410A07172 (why doesn't this have a US in the serial number?) Looking forward to advice on this situation. Thanks, Eugene W2HX --- looks like they solved the Apache Failure problem Edited by: w2hx on Sep 4, 2014 6:13 AM |

我不知道我发布的机会避免了Apache错误,但我会尝试。
您是否在Yahoo列表中看到了我对此的评论? 虽然标准仪器的内置测试装置起初看起来很吸引人,但它有缺点。 1)动态范围减小。 如果您有一个高衰减设备,例如在两个天线之间进行测量,您可以将检测到的信号直接馈入接收器。 这样可以增加动态范围,因为您不再耦合耦合器检测到的一小部分功率,而是全部耦合。 选项11的动态范围指定为110 dB,但我认为您会发现标准仪器约为100 dB。 2)我不确定,但我不知道是否可以用标准仪器进行混频器测量。 当测试集在外部时,您具有额外的灵活性。 3)如果您拥有正确的测试装置,选项011仪器的频率下限将为30 kHz - 我认为您所使用的85047A不会在那里工作。 但是通过更改该测试集,您可以在较低频率下工作。 4)如果测试装置是外部的,那么像频率扩展器那样构建它会更实用。 存在用于获取代码以将选项002,010和006添加到选项011仪器的源。 谷歌雅虎集团。 因此,我很清楚标准仪器是升级版。 有人可能会说选项011是标准仪器的升级版。 我很欣赏标准仪器更整洁,但外部测试装置确实可以提供更大的灵活性。 您可能会指出所有现代仪器(例如PNA系列)都内置了测试装置。但是大多数都可以选择“可配置的测试装置”。 这会在前面板上显示一些循环。 我认为这是一些选项015。 看一下这个易趣项目,看看是德科技出售的PNA。 注意前面板上的SMA-SMA循环? 这些是可选的,并提供灵活性。 http://www.ebay.co.uk/itm/Keysight-Agilent-E8358A-PNA-Network-Analyzer-300-kHz-9-GHz-Opt-010-015-/191267366290在我的8720D上有一个选项012 它将接收器买下了前面板。 我想要这个选项,并考虑购买必要的电缆和前面板覆盖层来添加它。 所以基本上你的新收购,内置的测试集,可能不是你认为的升级。 如果选项011仪器中缺少选项002,006和010,也许你应该考虑添加它们。 我怀疑如果你交换足够的位,你可以移动CPU。 是否明智是另一回事。 基于可配置测试集的优点,我当然不会。 戴夫 以上来自于谷歌翻译 以下为原文 I don't know what the chance of my posting avoiding an Apache error, but I will try. Did you see my comments on the Yahoo list about this? Although the built in test set of the standard instrument seems attractive at first, there are disadvantages of it. 1) The dynamic range is reduced. If you have a high attenuation device, like for example measuring between two antennas, you can feed the signal detected directly into the receiver. That gives you an increase in dynamic range, as you are no longer coupling a fraction of the power detected by the coupler, but all of it. The dynamic range of the option 11 is specified as 110 dB, but I think you will find a standard instrument is about 100 dB. 2) I don't know for sure, but I don't know if it is possible to do mixer measurements with the standard instrument. You have extra flexibility when the test set is external. 3) The lower frequency limit of the option 011 instrument will be 30 kHz if you have the right test set - I don't think the 85047A you have will work there. But by changing that test set, you could work at lower frequencies. 4) Building this like frequency extenders would be more practical if the test set is external. Sources exist for getting codes to add the options 002, 010 and 006 to your option 011 instrument. Google the Yahoo group. So it is far from clear to me that the standard instrument is an upgrade. One could argue the option 011 is an upgrade from a standard instrument. I appreciate the standard instrument is neater, but having the test set external does allow some more flexibility. You might point out that all modern instruments (e.g. PNA series) have the test set built in. But most of them have an option of a "configurable test set". This brings out some loops onto the front panel. I think it is option 015 on some. Take a look at this eBay item for a PNA being sold by Keysight. Notice the SMA-SMA loops on the front panel? Those are optional, and give flexibility. http://www.ebay.co.uk/itm/Keysight-Agilent-E8358A-PNA-Network-Analyzer-300-kHz-9-GHz-Opt-010-015-/191267366290 On my 8720D there was an option 012 which bought out the receivers to the front panel. I would like that option, and have considered buying the necessary cables and front panel overlay to add it. So basically your new acquisition, with the built in test set, might not be the upgrade you think it is. Maybe you should look at adding options 002, 006 and 010 if they are missing from option 011 instrument. I suspect if you swap enough bits about, you could move the CPUs over. Whether it is wise is another matter. I certainly would not, based on the advantages of the configurable test set. Dave |
