Logging 1 sample of a pulse

[antique]

I must be having one of these old timer moments.

I need to acquire a pulse sample and log it of an item running.

I would like to log the peak current of each pulse. This will be a 72 hour test and will need to take samples for 5 min at the beginning of a temperature cycle. Then wait for about 2 hours and sample the last 5 min of the cycle. This will continue for 72 hours.

The problem that I am having is that when I get the sample I get about 10 – 100 readings.

I only want 1 sample of each peak pulse. I am sure that this is something simple that I am over looking and I am trying to do this as simple as possible. Any help will be appreciated.

Well, you could take the samples that you collect and extract the maximum value to get the peak, or pass it to the mean function to get the average. There are lots of ways to reduce an array of values to a single descriptive value.

Hey antique,
    LabVIEW has some built-in peak detection VIs as well.  Here's a KnowledgeBase about one of them.  Just search the palettes for "peak" or search ni.com.
