Please help? Use Google Chrome if you cannot see the question.
I am doing a spike check automation program in Labview for an internship. I am tryingto detect the peaks and valleys from a probe test on a wafer. I am new to LV so any help is appreciated. The probes are attached to the wafer and connect to an oscilloscope. Right now finding the peaks and valleys are done manually but take a lot of time from one pin. My program has to optimally run for 30 seconds and, at every interval, of let's say 20 microseconds, has to take the worst case scenario for the peaks and take the screenshot from the oscilloscope and save it until the worst case scenario in the next block on 20 microseconds until the 30 seconds are up. I am using LV2010. I don't have experience with LV before. I have researched and found a VI called waveform peak detector which seems helpful but I am not sure how to save a screenshot at each interval. I am also unsure on what to put in a loop so my program can run continuously for 30 seconds with stopping. I also have the instrument drivers for my particular oscilloscope so I can control the scope from my computer and LV program. Any help is appreciated and thanks in advance for your assistance.Explanation / Answer
The LV-Excel-Add-In interface enables a bidirectional data exchange between your EXCEL-sheet and a LV program module. The entire Excel capabilities are still available while integrating a complete equipment design by an LV module. You may perform a complete heat exchanger design, generate your own specification sheets, perform a cost estimation and write this all to an EXCEL sheet by simply clicking on a single button; everything is done in your familiar Excel environment with your own defined output sheets.
Furthermore LV-programs may be controlled by the MS-Office programming language. This feature allows e.g. to generate complete data tables and analyze them by using the graphical tools of Excel.
For further use of LV-Sofware in other Windows programs you can use the client-server object-interface. This global programming interface enables the integration of every LV program module into other applications by using a suitable programming language like Java-Script or VB-Script. This is the way to integrate LV-modules into customers own programs.
