what's the maximum output voltage of labview

If you are trying to pulse or oscilate dc for digital logic or the like you just might want to build hardware to do that.

Power supply plus 555 timer, or something similar.

But, since I can't figure out what the heck you are asking and I can't help with the hardware right now.

hi

thanks for reply

it's not a rediqulas question ok it is something to do new innovative.

if i am able to  use the dc voltage of usb output then i dont need any DAQ card which are expensive.

so,  only want to know is it possible to controled the output of usb port, that output voltage is given to the oscillator circuit and oscillator will work as per the output dc volage of usb poort and that voltage of usb port will control by the Labview programming

thanks

Here is the maximum output voltage LabVIEW can output

Higher numerical values wellcome 😉  (Strings are not allowed)

However cheap analog output: Your soundcard !  For DC values add a diode and a Cap 😉

Max output voltage defined by your soundcard or the following amplifier 😄

Depending on your soundcard and the frequencies you want to generate you maybe don't need an oscillator, just use the soundcard .....

You have to be careful with sound cards.  Some are DC coupled and others are AC coupled.  So depending on your sound card, you may not be able to output DC voltages.

Is this a hobby job or project for a company?  You can get a simple USB DAQ for under $200.

It is not. The USB port is not a power supply for you to use in any way you see fit. It provides a fixed voltage to power computer devices. You seem to not want to accept the reality that you need to use an external device to properly generate a variable voltage. This, of course, is your problem, not ours. We are quite happy to accept the universe as it is.

This discussion really is worth being pinned on my personal wall of fame, really makes you smile on a sad day

thanks to all for theire reply

if  further probem occured with DAQ card then i will ask here thnk a lo

[husssey]

hello

now i purchased a DAQ card-USB-6008 to control and genrate the voltage 0 to 10v for that i had made one vi code, so now how can i control that voltage and how can i export the output at the usb port

here i am atteching my vi file

so kindly please find it

thanks

Your VI does not contain any code which communicates with the USB 6008 device.

The USB 6008 runs on NI DAQmx, so make sure that you have installed this. Test the device using Measurment&Automation Explorer (MAX) with the "Test Panel".

If everything works, search for examples in LV (LV Example Finder) on how to generate/acquire data.

Once you get accustomed to this, start adding your functionality to that examples. Please make sure that you are working on copies of the examples, not the original ones!

hope this helps,
