是否有可能将N9923A用于1.75 MHz？

嗨Dave，虽然我完全同情你的要求，但我们无法降低N9923A的启动频率。
我们多次看过它并决定不追求它;
太多的挑战。
但是，我们有一个新的分析仪N9913A，其启动频率为30 kHz。
您可能需要致电当地的安捷伦销售代表并询问折价。
也就是说，您使用N9923A换取N9913A，并查看您提供的价格类型。
此致，Afsi Moaveni

  Hi Dave,

While I fully sympathize with your request, we cannot lower the start frequency of the N9923A. We've looked at it many times and decided not to pursue it; too many challenges. However, we do have a new analyzer, N9913A, which has a start frequency of 30 kHz. You may want to place a call to your local Agilent sales rep and ask about a trade-in. That is, you trade in your N9923A for an N9913A, and see what type of price you are offered. 

Regards,
Afsi Moaveni

>>问候，> Afsi Moaveni谢谢Afsi，遗憾的是无法做到这一点。
我希望它能够 - 即使准确性受到损害。
只需10％的变化就是一个很好的补充。
我刚买了N9923A。
我在eBay上从安捷伦购买了CertiPrime单元。
我昨天只支付了安捷伦的费用，并且不会在这里预计它会持续3个星期，所以交易它并不是我真正的愿望！
在任何情况下，4 GHz和6 GHz之间的范围对我来说非常有用，因为我打算在该范围内设计出售的天线。
稍微低于2 MHz的能力仅适用于业余无线电，所以如果可以将其降低到1.7 MHz，那就太好了。
我确实有一个20 GHz的VNA，并希望tomorow能够接收一个覆盖300 kHz到3 GHz的旧HP 8753A。
这将涵盖160米的业余乐队，但我无法证明只为一个火腿乐队保留这一点，所以我很快就会出售。
我在购买Fieldfox之前就已经开始使用了它，但是自从购买FieldFox之后，功能上的重叠太多，以至于无法保留两个VNA。
我甚至为Fieldfox购买了价格昂贵的TDR选项，我可能会使用它。
我认为一个选项花费的成本与8753A一样多，它有TDR选项！

Thank you Afsi,

It's a shame it can't be done. I was hoping it might be able to - even if the accuracy was compromised. Just a 10% change would be a nice addition. 

I've only just bought the N9923A. I bought it as a CertiPrime unit from Agilent on eBay. I only paid Agilent for it yesterday, and are not expecting it here for 3 weeks, so trading it in is not really on my horizon! In any case, the range between 4 GHz and 6 GHz is quite useful to me, as I intend working on the design of antennas in that range to sell. 

The ability to get a little bit below 2 MHz was just for amateur radio use, so it would have been nice if it could have been pushed down to 1.7 MHz.  

I do have a 20 GHz VNA, and expect tomorow to receive an old HP 8753A which covers from 300 kHz to 3 GHz. That would cover the 160 m amateur band, but I can't justify keeping that just for one ham band, so I am going to sell that quite shortly. I bougth it before buying the Fieldfox, but since buying the FieldFox, there is just too much overlap in functionality to make it sensible to keep both VNAs. 

I even bought the lucdicrously expensive TDR option for the Fieldfox, which I might have a use for. I think that one option cost me as much as the 8753A  did, which has the TDR option!

Dave

我再次同意。
请相信我，我们已经一次又一次地详细查看了这个请求，并得出了相同的结论。
我理解您希望保留现有的N9923A。
我只是觉得你有4 GHz的盒子，这就是我推荐N9913A的原因。
我们有一个N9914A，最高可达6 GHz;
这个家庭实际上一直到26.5 GHz。
也许下一次...仅供参考，一旦你拿到了你的装置，如果你正在寻找任何类型的文件，请查看www.agilent.com/find/fieldfoxsupport问候，Afsi

  Again, I agree. Trust me that we've looked at this request in detail, time and time again, and come back to the same conclusion.

I understand your desire to keep your current N9923A. I just thought you had the 4 GHz box, which is why I suggested the N9913A. We have an N9914A which goes up to 6 GHz; the family actually goes all the way to 26.5 GHz. Perhaps for the next time ...

FYI, once you get your unit, if you are looking for any type of documentation, check out www.agilent.com/find/fieldfoxsupport

我不是第一个要求频率降低一点的人。

I assume from this that I'm not the first to request it went a bit lower in frequency. 

Dave

那将是一个正确的假设。
