Virtual nstrument

[Gem_Pasha]

Is there any virtual Instruments in Labview like the ones available in NI Multisim, such as Spectrum Analyzer, Digital Oscillospe, Agilen DMM, etc. ?

Look at IVI and soft panels

Thanks for your reply, Could you give some detailed information ? I'm a new user of Labview and I don't understand What you mean by IVI and soft panels ?

If I understand you correctly, do you need Virtual Instruments [VIs] to start programming the various hardware?

If so, try to look into the Instruments I/O pallette in your LabVIEW Functions pallette. You ll see the necessary VIs installed in them corresponding to your hardware configured/connected to your system.

If I m wrong, please clarify me.

I'd like to use these kinds of VIs in their simulated mode, not for programming hardware. When I look at the Instrument I/O->Instrument Drivers in Functions palette, there is only Agilent 34401 hardware. I'd like to install VIs for other basic measurement instruments and run them in simulated mode.

The only built-in simulation for instruments is to use IVI drivers. See Types of Instrument Drivers to get an overview of IVI. You'll probably have to create your own front panels. For full details, you can go to the IVI Foundation.

Do you know the location of IVI instrument drivers for LabView ? or Should I download them from IVI foundation site ?

[Dennis_Knutson]

Class drivers get installed when you install the IVI Compliance Package. Instrument specific drivers can be downloaded from either the Instrument Driver Network, the IVI foundation, or from the instrument vendors themselves. It all depends on the instrument, the vendor, and the type of IVI driver you want.

I realized that I'd like to use VIs similar to the Virtual instruments in NI Circuit designer, I'm not interested in the programming and other issues of the devices, I'd like to obtain devices like in the real life, Connect input signal and measure and see the results on their screen. Is this possible ?

You will have to do some programming. There are numerous functions in LabVIEW that will allow you to simulate sources and measurements. For example, there is the Express VI called Simulate Arbitrary Signal. There is a shipping example called Two Channel Oscilloscope. This generates a sine wave and a square wave, adds noise, and then displays the waveforms on a LabVIEW graph. How much work it will take will depend on the types of signals you want to simulate and what type of measurements you want to do.
