DSO-X2014A如何记录USB记忆棒中的长时间连续

这是我为3000X，2000X的大哥哥写的东西...... 3000X示波器是一个伟大的“基本”示波器，但如果它的主要目的是“永远记录”，你将不会满意。
请继续阅读。
因此......当前（或之前）可用的示波器不能无间隙地“记录”数据（将波形X-Y数据写入存储设备）。
一般来说，所有示波器的工作方式如下：填充预触发缓冲器Arm Trigger Acquire Go blind，同时重新填充预触发和重新布防这个盲目时间通常比捕获的时间长，通常为90％或更高
。
将数据卸载到存储设备使得盲区时间更长。
深存储器范围可以捕获具有长记录长度的信号，然后将它们存储起来......
但这里总会有差距。
实际上，3000X具有市场上任何示波器的最低盲区时间，但这只是在示波器运行时，而不是在存储数据时。
范围可以非常好的另一件事是：对它们进行编程以进行一些测量并将该测量结果写入PC，例如每秒一次Vrms。
新的BenchVue软件也可以做到这一点：http：//www.keysight.com/find/benchvuescope 3000X是一款出色的示波器，但如果这是它的主要用途，我怀疑你会不高兴。
但是，通过升级的内存选项，它可以以最大8 kSa / s的速度捕获500秒。
对于较短的时间捕获，它可以具有更高的采样率，高达4 GSa / s。
然后，您可以关闭数据，然后重新开始。
具有更多内存的更高性能示波器（例如9000A系列，www.keysight.com / find / 9000）可以更长时间地保持更高的采样率。
现在，如果您正在处理脉冲，分段存储器可能非常适合您：使用示波器的分段存储器更有效地捕获信号AN 1573 http://literature.cdn.keysight.com/litweb/pdf/5989-4932EN.pdf
*要点：*如果你真的需要永远记录，你需要一个数字化仪（并不是所有的数字化仪都能做到这一点）。
范围旨在为您的眼球提供数据。
数字化仪旨在将数据提供给硬盘驱动器或其他存储介质。
这是关于“永远记录：”捕获长时间或高数据量事件的应用说明http://cp.literature.agilent.com/litweb/pdf/5990-7734EN.pdf www.keysight.com/find/digitizers许多
数字化仪将提供分段存储器，但只有少数可以在导出先前获得的段时获取新段。
然后是数据记录器。
通常这些用于非常特殊的目的，例如监测温度或DC电压。
记录采样率通常很低，如果是这样，可能是1 kHz。

  Here is something I wrote for the 3000X, the 2000X's big brother...


The 3000X oscilloscope is a great “basic” oscilloscope, but if its main purpose will be to “record forever,” you will not be happy with it.  Please keep reading.   So… no oscilloscope currently (or previously) available can continuously “record” data (write waveform X-Y data to a storage device) without gaps.

Generally speaking, ALL scopes work like this:
Fill pre-trigger buffer
Arm
Trigger
Acquire
Go blind while re-filling pre-trigger and re-arming <- *Key Point*

This blind time is usually quite long compared to how much time is captured, usually 90% or greater.  Offloading the data to a storage device makes that blind time even longer.

Deep memory scopes CAN capture signals with long record lengths, and then store them off…. But here will always be gaps.  The 3000X, actually, has the lowest blind time of any oscilloscope on the market, however, this is only while the oscilloscope is running, not when it is storing data.


Another thing scopes can be very good at is: programming them to make some measurement and write that measurement to a PC, say, Vrms once a second. The new BenchVue software can do this, too: http://www.keysight.com/find/benchvuescope 

The 3000X is a great oscilloscope, but if this is its main intended purpose, I suspect you won’t be happy.  However, with the upgraded memory option, it can capture 500s at 8 kSa/s max.  for shorter time captures, it can have a higher sampling rate, up to 4 GSa/s. Then you can store the data off, and start again.  Higher performance oscilloscopes with more memory (such as the 9000A series, www.keysight.com/find/9000 ) can maintain higher sampling rates for longer.

Now, if you are working with pulses, segmented memory might be perfect for you:

*Key Point:* 
If you really need to record forever, you need a digitizer (and not all digitizers can do this).  Scopes are designed to get data to your eyeballs.  Digitizers are designed to get data to a hard drive or other storage medium.  Here’s an app note on “record forever:”

Capturing Events of Long Duration or High Data Volume
http://cp.literature.agilent.com/litweb/pdf/5990-7734EN.pdf

www.keysight.com/find/digitizers  <- In general the Acqiris line of digitizers can do this.  Most of the Acqiris digitizers support segmented memory.

Many digitizers will offer segmented memory, but only a few can acquire new segments while exporting previously acquired segments.

And then there are data loggers.  Typically these are for very special purposes, like monitoring temperature or DC voltages.  The record sampling rates are typically low, like maybe 1 kHz, if that.

您好ksmith，很多，非常感谢您的解释，我仍然在学习示波器的使用，我的老版本是类比的。
关于记录数据，BenchVue对我来说是一个很好的解决方案，非常完美。
更多时间让我学习所有工具我的设备。
更多的一次非常感谢你的帮助。
拥抱。
Francelo

  Hello ksmith,

Many, many thanks for your explanation, I still learning the usage of my oscilloscope, my old is analogic.

About of record data, BenchVue is good solution for me, perfect. More time for me learning all tools my equipment.

More one time many thanks for your help.

Hugs.
