Hi Dasheng,

There are 3 separate ways to generate a square wave using your M series card.

Good: Digital Output

Better: Analog Output

Best: Counter Output

There are some great examples for generating a square wave in the LabVIEW Example Finder. A good Analog Output example is located in:

Help>>Find Examples>>Hardware Input and Output>>DAQmx>>Analog Generation>>Voltage>>"Cont Gen Voltage Wfm Int Clk."

A good Counter Output example is located in:

Help>>Find Examples>>Hardware Input and Output>>DAQmx>>Generating Digital Pulses. I recommend taking a look at "Generate Dig Pulse Train-Continuous.vi."
