新手第一次使用光电编码器，我想用光电编码器来采集发动机的瞬时转速。请教怎么将光电编码器接入PXI-6259数据采集卡上？
光电编码器说明见附件（型号：LF-36BM-C05D)。

把信号A或B接入板卡，测量方法不同则接线不同：
低频（如用CTR0）：接计数器的GATE0
高频2个计数器（如用CTR0和CTR1）：接SOURCE1
大范围2个计数器（如用CTR0和CTR1）：接SOURCE0

首先谢谢您的回帖。因为第一次接触光电编码器对它还不了解，所以我还想问一下A或B接不采集卡，那A’或B’怎么办？不接，还是接到GND？期待您的回复！

A,A'和B,B'分别是两个差分信号，可以先把他们转换成单端信号，Aout，Bout，然后在接到采集卡上
