I've struggled for a while to figure out how to take readings at fixed intervals from my counters and other GPIB gear. The problem is that the time it requires to trigger and receive a measurement is non-zero and can vary from measurement to measurement. Trying to calibrate a proper delay is an exercise in frustration, and any errors mount over long experiments.
I searched the web and found bits indicating that a fixed timer could be done using an "alarm" signal, but no single place provided a useful (to me, anyway) example, and all the info I found seemed aimed at different applications. I finally figured it out, and the details are at http://www.febo.com/pages/perl-alarm-code/index.html if this might be of interest to any of you.
