AARONIA实时频谱分析仪V6 Spectrum Condition 模块的功能是允许客户在masks、spectral density以及logical data processing中做触发。


左侧输入:
-Spectra
右侧输出:
-Spectra
-Filtered (Spectra)



有了AARONIA实时频谱分析仪V6 Spectrum Condition 模块,我们就可以无限可能的对spectra stream中的任何事件进行触发。
有了Time compression的帮助,我们就可以在spectra stream生成最大保持,这可用于在较长时间内生成触发掩码。
在Condition中,我们可以设置相关的逻辑处理:Channel (C0 to C3), Operation (Set, Set Not, Or, Or Not, And, And Not), Hold (no of samples), Ignore (no of samples)。此外,我们还可以选择spectral density level(s): Min Inside (spectral density in %), Max Inside (spectral density in %):
在Frequency Mask中可以创建一个或多个触发掩码,在菜单中可以选择Add Mask、Build Mask from Data、Export Masks、Import Masks、Remove all Masks,trigger mask可以显示为一个Area,可以在图形中重命名、编辑或拖动/移动该区域,根据需要编辑掩码数据表中的掩码数据。


默认情况下,实时触发数据以黄色轨迹显示,而非触发数据以蓝色显示


通过Spectra and Filtered block output添加spectrum 视图,可以实时比较触发和非触发数据。

"Spectra"输出接口将输出完整的输入流,并在与条件匹配的样本数据上设置标记;
"Filtered"只输出符合条件的样本数据,如上面的屏幕截图所示。

By default, all frequency masks are assigned to the same condition flag, so any subsequent trigger will react to all of them equally. Using the Extensions it is possible to define multiple independent conditions, so a trigger can react to each of them individually. Also each Extension will have its own dedicated output, so you can analyze or record them separately.

This was all possible before already by using multiple AARONIA实时频谱分析仪V6 Spectrum Condition模块, with the Extensions its just a bit easier when you can see all frequency masks in the same graph.
