Controllable DC voltage

[BinJiao]

Hi all：

Excuse me, I now need to use LabVIEW to control NI data acquisition card USB-6366 to generate four ±5V DC voltage signals. At the same time, the signal can show a step-like controlled (higher voltage and time accuracy) gradually become 0V. Can you give me some advice?

Hi BinJiao,

the signal can show a step-like controlled (higher voltage and time accuracy) gradually become 0V.

Can you explain this more detailed? Maybe with an image?

Which signal? What means "show a step-like controlled"?

What means "controlled gradually becomes zero"?

[BinJiao]

That is, the voltage is changed from the original amplitude to 0V in stages, and the duration of this phase is controllable.Just like the picture shows.

Hi BinJiao,

use an autroindexing loop with two inputs: an array of voltages and an array of time/delay values.

In the loop you set the voltage level and wait for the delay value…

Thanks a lot.

It's definitely a great way to do it, but I'm a novice, and I'm not going to use LabVIEW too much.

I tried, but I didn't reach the goal.How can I do that?

Please give me more specific hints

As described before:

There is a "Learn LabVIEW" section on top of the LabVIEW board., for novices like you.

And it's a shame you will not use LabVIEW that much…
