Timed increase in frequency into "simulate signal.vi"

[JacktheLad]

Hi all, I'm an absoulte beginner with labview so any help would be greatly appreciated, I want to increase the frequency of a generated sine wave, created using the simulate signal.vi, in set increments over time.
In other words I want the simulate signal.vi to produce a sine wave that will over a set period of time increase in frequency from say 39.5kHz to 41.5kHz, in increments of 0.1hz.

Thanks in advance for any help.

Here's one way to do a basic sweep.

Thanks that looks great, by any chance would you have a copy of that as a program, there's just a couple of elements I'm unfamilar with. If you could provide the .vi I would be greatly appreciative. Thanks again for your help so far.

What are you unfamiliar with? All of the express functions have their name and you can use the search button on the functions palette? The only only thing you might need is a shift register and you get that by clicking on the border of the for loop. You might want to check the free tutorials.

You don't mention which version of LabVIEW you are using so here it is as 8.0.

Hi again, thanks for that. It was just the "for loop" I was unfamilar with, I haven't come across it yet in the tutorials I use. Thanks for all your help. It is greatly appreciated.
