Rough translation from Chinese to English:

Kind of acquisition card can achieve precise sinusoidal signal inverted moment generates a trigger signal

Hi,

Please post in English in this board for more responses.

Give more inputs what is your exact requirement?

I think he 's asking which DAQ board can accurately generate a trigger signal when the phase of sinusoidal signal changed at n*180 degree (It's the intersection of x axis and the Sine wave if the sine wave is symmetric to the x axis).
