SCPI跟踪N9340B上的数据如何获取x轴数据

嗨，我试图从N9340B转储跟踪数据。
通过编程手册，很容易获得y轴数据，但我不确定如何获取x轴数据，我似乎无法在那里找到任何对它的引用。
具体来说，我想知道以下两个公式中的哪一个是正确的（如果是！）因为我不确定它如何分割箱：N =箱数（整数）Fstart =起始频率Fstop =停止频率F =频率*
bin center * X = bin number（整数）F = X *（Fstop - Fstart）/（N-1）+ Fstart或F =（X + 0.5）*（Fstop - Fstart）/（N-1）+ Fstart Can
有人帮我这个吗？
或者，如果我错过了记录的地方，那么如果你能指出我在哪里就会很棒:)谢谢！编辑：jeremyherbert于2016年1月28日上午6:18;

  Hi,

I am trying to dump the trace data out of an N9340B. Looking through the programming manual, it is easy to get the y axis data, but I am unsure of how to get the x axis data and I can't seem to find any references to it in there. Specifically, I am wondering which of the following two formulae is correct (if either!) as I am not sure how it segments the bins:

N = number of bins (integer)
Fstart = start frequency
Fstop = stop frequency
F = frequency at *bin center*
X = bin number (integer)

F = X * (Fstop - Fstart) / (N-1) + Fstart

or

F = (X + 0.5) * (Fstop - Fstart) / (N-1) + Fstart

Can anyone help me with this? Alternatively, if I have missed where this is documented, it would be great if you could point out to me where it is :)  

Thanks!
