what's the maximum output voltage of labview

[husssey]

hi

i want to give 0 to 10v to the oscillator circuit so for that i would like to know that maximum output voltage of labview because i want to oprate my oscillator using labview program

LabVIEW is a programming language and will never be able to generate voltage. It can only tell hardware to do so.

What hardware are you using for voltage generation (i am NOT referring to your PC's power supply!)?

hi

so it's not possible to genrate dc volage by computer to write a labview program in it

[Norbert_B]

Where would you expect the DC voltage to come out of your PC?

If you don't have a specific hardware for this, would that be the fan? Probable not... the DVD drive? Most probable not as well....

You NEED specific hardware for this. Something like NI DAQ devices.

And sure you can use LV to use such devices for generation of DC voltage.

hello

thanks for reply

yes i want to genrate dc voltage from my computer to drive  oscillator circuit which will be oprated by Labview

hussey,

this discussion has no worth.

We KNOW that you want to generate voltage using the programming language LV.

Since no programming language in the world is able to generate voltage without dedicated hardware, repeating "I want to use LV to generate voltage" several times will not bring you anywhere.

What kind of hardware do you have for voltage generation mounted in you PC?

What else do you want to generate except DC voltage (controlling an oscillator could include also AC voltage stimulation...)?

USB ports have a 5V out, but it has nothing to do with LV.

[husssey]

thanks yameda for your fevorable reply

ok so i am accepting whatever you say but one more question is there, why we can not use that 5v from the usb port?

there is not any method 

thanks

[Norbert_B]

USB port outs 5V DC statically. It's like power outlets which (in Europe) out 230V AC all the time (except the fuse is blown or you have a black out).

So, you don't need any programming language to conrol that 5V output of the USB port. 

Norbert 

EDIT: What voltage do you need? What power does the circuit consume? Do you require some kind of programmatic modification of the voltage?

If you don't answer those questions (in addition to my previous ones) we simply CANNOT help you....

Here you say you have to interface to the oscillator with a DAQ card. So why the ridiculous questions about the pc being the source?
