I want to apply single square or sine wave

[sonic]

Now I used NI-FGEN and NI-Scope for bender element test, I want to know how to generate single sine or square wave for input wave by using NI-GEN and how to recieve the sigle wave by NI-Scope(normally in NI-FGEN, I saw only continuous wave generation type).Is it possible to solve this problem by using only NI-FGEN and NI-Scope only ? (without LABVIEW). Thanks you so much

Hi,

Thanks for contacting National Instruments. The NI-FGEN and NI-SCOPE drivers do not only have to be programmed using LabVIEW. They can also be programmed using CVI, C, and Visual Basic.

If you don't want to do any programming and would rather just generate and acquire waveforms with basic functionality you can use the soft front panels (SFP). There is a NI-SCOPE SFP and a NI-FGEN SFP. These can be found by going to Start >> Programs >> National Instruments and choosing NI-SCOPE or NI-FGEN. You will see the SFPs in these directories. NI-FGEN SFP will allow you to generate both square and sine waves at different frequencies and amplitudes. NI-SCOPE will allow you to read in waveforms at various sampling rates.

Hope this helps!

Dear Erick,
Thank you for your suggestion, anyway I try to use NI-FGEN SFP and select the "Standard function mode" but in the triger type I cant select the "Single" I found only "Continuous". Moreove, I try to select other function mode and in the trigger type I can see the "Single", but after I select it and apply input wave in the NI-Scope monitor shows the continuous wave form.

The NI-FGEN SFP has limited functionality and can only operate under "continuous" triggering in the "Standard function mode". If you have LabVIEW though there is an example program already built that does exactly what you need to do. It's called niFgen_Trigger_Example.vi and allows the user to select the type of waveform, type of trigger, and the trigger source.

If you would rather program using C there is a program called "Triggers.c" that has the same functionality.

All the example programs can be found in the following path: Start >> Programs >> National Instruments >> NI-FGEN >> Examples.

Hi,
I am also trying to program bender elements in triaxial soil appartus. if you have done it already I would be appreciate if you get back to me and let me know about your program,
thanks,
