interpolated fast Fourier transform

Glenn

Hi:
First let me say that SignalScope for the iPhone is very good.  It is also well timed for me as our Church has horrible acoustics and I have the challenge of fixing it. 

Several Questions;

* I am having difficulty manipulating the trigger options.  A short tutorial would help.
* In the Spectrum Options - Data window, there are 7 options.  I am not a mathematician so could you elaborate on which interpolated fast Fourier transform is appropriate for different tasks
* I am also having difficulty manipulating the time scale in the Waveform mode.

Glenn,

Thank you for your compliments.

I am having difficulty manipulating the trigger options.

We do plan to add a reference section to the SignalScope Help. What would you like to accomplish with triggering?

In the Spectrum Options - Data window, there are 7 options.

You may want to look at this post.

I am also having difficulty manipulating the time scale in the Waveform mode.

We do plan to make this easier.
