Hi;
You can use compression record to take statistics. (some of option for N to
1 compression).
Thank you.

Subject: Re: Maximum of a waveform record
I remember there was a first attempt (about a year ago) to bundle a
bunch of existing waveform signal processing records into a soft support
module and make it available for download. (I remember some records
doing statistics - similar to what you need - from APS and a digital FFT
record from LANL.)
Does anyone know how far this attempt got? Does anyone feel responsible
for it?
Cheers,
Ralph
