Measure pulsewidths and amplitudes of 3-phase pulse using PXI-5122

[HotDogWater]

Hello,

I am trying to measure the pulsewidth and amplitude of each of the three sections of the attached pulse.  Basically there will be two negative sections and a positive section in between.  Each may have a different amplitude and/or pulsewidth.  Is there any fairly easy way to do this on the 5122 (using CVI)?  I was thinking perhaps there's a way to only capture each of the three segments separately, and let the digitizer do the relatively simple analysis.  Please see the attachment for a picture of what I'm trying to measure. 

Thanks!

P.S. If you can figure out a method for measuring the deadtime in between the 3 sections, and a method for determining whether the pulse is fairly square, you get extra points.  😄

determining whether the pulse is fairly square ....

Using a Histogram of all pulse values? If it is a pure pulse all values will be in two bins .... 

You didn't provide a coarse  time scale. Is it  p/n/µ/m seconds? 

So my approach out of the cristal ball:

Set up the 5122 to absolute timescale , set up trigger to 5% pretrigger with multiple shots , each shot long enough to hold one tripple pulse

fetch one shot , seperate the pulses (find slopes seperate inbetween) , make histogram.... do analysis (hope you have the time for it)

time between tripple pulse is the difference in the trigger timestamp

(In LabVIEW I would use multiple loops in parrallel with queues... )
