Sine, Square & Sawtooth sweep generation with variable duty cycle/rise time & fall time

[Test Signal]

Dear All !

I request and need some candid advices on the subject issue keeping in view the following notes:

1) I am a novice in LabView.

2) I was an average Electronics Engineering graduate who graduated about 9 years ago and since then I have not been involved in Electronics Engineering.

I have undertaken a task or generation of Sine, Square and Saw Tooth wave forms. All these waveforms are to be frequency swept form 1 Hz to 100 kHz. The amplitude of all these waveforms should be able to be adjusted. The duty cycle of Square Wave should also be adjustable (or better be able to be swept). Likewise the rise time and fall time of sawtooth wave should also be adjustable (or better be able to be swept).

I am considering  other options as well but wanna try it on LabView.

I wish to ask that is it possible to execute this task in Labview 7.0? If possible then considering the para 1 & 2 above, is it possible for me to finish this task in 15-20 days if I work on this for about 3 hours a day? If not then what can be reasonable estimate?

I will be extremely grateful if you people can offer advice on whole project or part(s) of it.

Thanking you in advance and requesting urgent response(s).

If you have at least the full version of LabVIEW, then you have set of waveform generation functions. These can be used to generate the signals aong with an NI DAQ board. An experienced programmer might be able to write the program in a as little as 3 hours total. How long it wouldw take you is going to be somewhat higher but depends on how much time you are willing to invest in learning the basics first.

Check this thread.

I did some similar coding, it might be usefull to you.

I am using ver 9.0 though.

If you work 3hr /day for 2 weeks you might as well finish book basics 1& 2 and than can do whan you need in a breeze, couple of hours.

Good luck
