how to analog output sine waveform with 50mv vpp and 50hz with PCI-6251 ?

[ateproject2007]

how to do that ? thanks a lot.

Hello Ateproject2007,

Assuming you're using LabVIEW and NI-DAQmx there is an example VI you can use.  If you open LabVIEW you can access examples by going to Help» Find Examples... Then navigate to Hardware Input and Output» DAQmx» Analog Generation» Voltage» Cont Gen Voltage Wfm-Int Clk.vi.  This example should be able to do what you want.

Have a great weekend!

i am useing this example vi your mentioned. But the problem is that PCI-6151 cannot get a stable ,precise, so small vpp value 50 mv and 1khz sine waveform, And i tried use this vi to generate vpp 2v ,then through a voltage divider to get VPP 50mv.But the signal has too much noise to get stable. Pls suggest how to get a more good quality such a small vpp value signal . thanks a lot.
