signal in the form of stair

[zeeley]

Hello Excused me for my  bad english I'm french, I want to create a signal in the form of stair to load a battery via a generator of current. I wish to choose in face-front the duration and the amplitude of every march for example 2v during 30min for the first and 3v during 1h for the second. I work with a NIPCI 6289 and Labview 8.0. Cordially

Sounds like you want to generate a Staircase voltage signal on an AO channel of your DAQ card

Right??

Just keep performing one point Generation on the desired channel and wait for the specified interval between each generation

Hope this helps

Hello Richard K, Thank you for your help, but I can't use your vi because my version of labview is more ancient(labview 8.0) than your. Could you save your program on labview 8.0 please. Cordially.

Hello, Richar K. It is still me I modified that you had given me but I wish to show the signal in the form of stair on a graph but it does not appear to it. Can you help me please. Cordially.

Hi,

In order to see what you generate, you'll have to acquire on another channel the signal you've generated. I recommand you to use the basics acquisition exemples of LabVIEW.
