Generate DC pulse(with user i/p amp, width) as analog O/P

[vidar]

My application in LabView requires to continuously generate a sine wave at a node(Analog O/P1) while simutaneously generating a dc pulse at another node(Analog O/P2) whose amplitude and width are user input. A continuous acquisition at the sine wave generation node(Analog I/P 1) is also required. I use a MultiDAQ PCI 6036E. I found solutions for the simultaneous sine O/P and data acquisition, but am unable to find a solution to generate the DC pulse(+/- 5V).

Vidar,

With regards to a LabVIEW example that demonstrates how to output a DC pulse on an analog output channel with a user defined amplitude and pulse width, it does not appear that one currently exists. I would suggest that you take a look at the following example program:

Continuously Generating a Waveform and a DC Voltage on Multiple AO Channels


This example continuously outputs a sine wave on one analog output channel and a dc voltage on another. You will need to modify the example to output a pulse (create an array containing values to represent the proper pulse, both am
plitude and width) in place of the dc voltage. This example does a good job of demonstrating the proper procedure for using multiple analog output channels simultaneously.

Good luck with your application.
