问 SPS与采样速率（sampling rate)之间有什么关系？
SPS好像是传输速率？英文缩写是什么？

一般的AD芯片中都有这样的字样
Analog I/O
Multichannel, 12-bit, 1 MSPS ADC 答 1: 1MSPS表示1兆采样点每秒。 答 2: 谢谢，圈圈那请问SPS与采样速率有什么关系呢？
是不是SPS的值越大，采样速度越快，还是只是单纯一个衡量传输速度的指标？ 答 3: 参考http://bbs.21ic.com/club/bbs/list.asp?boardid=6&page=1&t=1994309&tp=%u63A2%u8BA8AD%u8F6C%u6362%u4E2D%u7684%u51E0%u4E2A%u6982%u5FF5%uFF1A 答 4: 最大SPS，就是你实际最多能做到的采样速率。就是假设其它的东西足够快，你最多也只能到最大SPS的采样率。

sps: Samples per second. In data conversion, an analog signal is converted to a stream of numbers, each representing the analog signal's amplitude at a moment in time. Each number is called a "sample." The number sample per second is called the sampling rate, measured in samples per second. (FROM MAXIM GLOSSARY)
