Waveform Integration

[Matt G]

Currently, I'm examining luminescence through scanning through wavelengths on a monochrometer and averaging the signal on the oscilloscope, storing it all in an array and graphing in the end. 

My goal is to time-delay the value attributed to each wavelength in order to weed out rapidly decaying noise in my samples.  The light source is now chopped, and a trigger line feeds into the oscilloscope, which works fine with another program I have modified that examines the triggered waveform.

Basically, what I want to know is
Can integration under a specific area be done either:
    through adjusting instrumental settings (I'm using a Tektronix TDS 220, interfacing through GPIB)
    or through manipulation of a triggered output waveform using integration with specified boundaries relative to the trigger time?

I'm a college student new to Labview (~2 weeks now), so thanks for any help.

Hey Matt,

I'm a little unsure what you're trying to implement, but I think you should be fine doing what you're requesting at the bottom. You can either manipulate the array once it's within labVIEW, or you should be able to send specific commands to the GPIB instrument. I'm unsure if you've had a chance to use this example, but if you open up labVIEW and go to Help->Find Examples->Search for "GPIB" and you should be able to find "LabVIEW<->GPIB.vi"

This is a great VI, and you can beging sending signals to your instrument with this example. The one thing I can recommend is to find a list of all the commands the instrument is capable of, that information would be found inside the user manual of the instrument. Usually what you can do on the front panel of the instrument, you can do using a modified version of the example.

Can you let me know if this helps?

Regards,
