how to I measure peak to peak of a sinusoidal waveform?

[oilyfingers]

I'm looking for a simple way to measure peak to peak on a steady waveform input from a generator. I'm already using the harmonic distortion analyzer VI to get the frequency, and the basic DC/RMS vi to get the DC and RMS values. But I also want the peak to peak. The signal isn't necessarily going to be sinusoidal, but it will be regular and steady. Is there a simple VI that will give me the peak-to-peak? There is 'statistics' (express VI) but I'd prefer not to use an express VI, although I suppose I could do the 'replace with code' thing..

sorry - subject should not say 'sinusoidal' (it is at the moment, but might not be)

Waveform Min MAX or Array Max & Min can be used. Just add the absolute values together.
