NI Waveform Match Trigger Example for the NI 5171R

[Example_and_IP_Admin]

Description

This package installs an example for performing a waveform match trigger using the NI PXIe-5171R reconfigurable oscilliscope.  A waveform match trigger is a real-time trigger that allows the user to define the shape of a waveform as a trigger.  This allows the user to isolate anomalous waveforms that may be difficult to find using traditional triggering methods. FPGA and Host example code is included.  A more detailed technical discussion of this example can be found here.

Thanks much for sharing this IP to all users!  I remember this great examples was demonstrated back in NI Week 2014.  I wish NI had better advertised this kind of combinations of wonderful HW and SW back in thoses days, so that NI would have dominated the market of FPGA + IO instrumentations.  

This is a good example for imtermmediate to advanced programmers of LV FPGA as well.

Wouldn't it be better to immdiately compare incoming data against all the limits, then, store the comparison results, rather than to store input data themselves?  This way, we may be able to replace data path of incoming data with boolean data of comparison resoults and save some FPGA resources.
