NI 9263 dc voltage output

[cortexkilkis]

how can i send the signal to the channel that i chose and see that in a oscilloscope?

Hi kilkis,

use DAQmx functions to set an AO voltage.

Then use (real copper) wires to connect your NI9263 with your scope.

my output is digital how can i produce and send the digital pulse(constant) to a channel of my card(i have NI-9402

Hi kilkis,

use DAQmx functions!

Hint: LabVIEW comes with a huge example library…

Hello i send a PWM signal to a digital channel( so i use 1 sample on the signal simulation tab ) I want my duty cycle to start from 0 to 100% with a  step controled by me,increasing it every 100ms (RATE in circuit). I make a while loop to add Function but the value doesn't reach duty cycle. How can i do this?

Hi cortex,

How can i do this?

Create a VI working exactly on your requirements…

i use 1 sample on the signal simulation tab

You create a PWM with just one sample? How will that work?

increasing it every 100ms (RATE in circuit).

Which circuit are you talking about? Is there  a PCB connected?

On your image:

- Ever heard about creating screenshots without using a camera or mobile?

- Cleaning up the block diagram before making screenshots usually increases readability of the code.

- hiding settings in ExpressVIs doesn't help to increase readability

- attaching an image of a VI doesn't help us to debug your VI

Conclusion: Attach your VI!
