how generate a digital output(square wave) through scxi-1325?

[sweet dream]

We are using SCXI 1000 chassis and SCXI 1124 module for voltage generation. Can we generate an output signal through labview software??

signal range : 30sec (trigger) and  30sec (rest) = possible to time control

output range : control

Hi Sweet Dream,

Welcome to the forums! Using the SCXI-1124 you can in fact generate an output signal with LabVIEW.  LabVIEW comes with a number of previously written example programs which you can use “out of box” or else modify to meet your application’s needs.

One of these examples, Cont Gen Voltage Wfm- Int Clk- Non Regeneration.vi, seems like it would meet your exact needs. It is a previously written VI that allows the user to select the Timing, Waveform Type, Frequency, and Amplitude of the voltage generation. The amplitude and frequency of the waveform can be changed by the user while the program is running. I am assuming that when you say signal range you meant a 30 second high and then a 30 second low square wave with user defined amplitude. Is this correct?

This example can be found in LabVIEW by navigating to the Help Menu>> Find Examples>> expanding the Hardware Input and Output folder>>expanding the DAQmx folder>> expanding the Analog Generation Folder>> and then looking in the Voltage file. When you click on an example VI, a brief description will appear in the Information box to the right of the Example Finder.

Hope this helps, Mallori M.
