嗨,E4440A的所有默认设置,如扫描 - >点是601,如果所有其他参数保持不变,如果我将点数增加到8000,数据显示会花费更长时间吗?
我自己检查,几乎没有看到差异。 非常感谢您的帮助! 你的,Yiliu如果E4440A用于大规模生产设备的自动测量,是否有关于扫描点设置的经验法则?编辑:wangyiliu于2013年2月8日12:25 PM 以上来自于谷歌翻译 以下为原文 Hi, all default setting of E4440A, as in sweep -> points is 601, if all other parameters being kept the same, would it take longer as for the data display if I increase points to 8000? I checked by myself and barely saw the difference. Your help would be highly appreciated! Yours, Yiliu If E4440A is used as in the automatic measurement of mass produced devices, are there any rule of thumb concerning the sweep points setting?

嗨 - PSA有一个全数字IF,采样率为30 Msamples / s。
例如,如果您的扫描时间是1秒,扫描/跟踪点是601,那么每个跟踪点桶有30个Msamples /(扫描点-1)样本,相当于50,000个样本。 如果将扫描点增加到8001,则每个跟踪点桶为30E6 / 8000个样本,即3,750个样本。 如果您的检测器是峰值检测器,那么在每个跟踪点桶中的所有样品中,分析仪将保留最高样品并使用它来表示跟踪点。 因此,正如您所看到的那样,除了可忽略的时间之外,除了可以忽略的时间之外,分析仪在显示器上绘制额外的点之外没有时间惩罚。 但是,当您增加扫描点时,每个扫描点都会在较少的样本上进行测量,因此您将看到点的幅度变化更大。 问候 - 以上来自于谷歌翻译 以下为原文 Hi - The PSA has an all-digital IF that samples at 30 Msamples/s. If for instance your sweep time is 1 second and your sweep/trace points are 601, then each trace point bucket has 30 Msamples/(sweep points – 1) samples, which equals 50,000 samples. If you increase your sweep points to 8001, then each trace point bucket is 30E6/8000 samples, which is 3,750 samples. If your detector is peak detector, then out of all of the samples in each trace point bucket, the analyzer will keep the highest sample and use this to represent the trace point. So, as you can see there is no time penalty for having more sweep points other than the negligible time it additionally takes the analyzer to paint additional points on the display. However, as you increase the sweep points, each sweep point is measured over fewer samples, so you will see more variability in amplitude of points. Regards - |
