8753D固件版本CPU 000选项混乱

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。

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。

  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.

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.
