I am testing fabricated transistors via GPIB. I have a Keithley power supply biasing the Drain/Source and an Agilent Power Supply biasing the Gate/Source. I am new to LabVIEW. My program is fully functional, but I am trying to export the data to an excel spreadsheet and I'm having quite a bit of complications. The XY graph is taking in a 1-D cluster array of complex data. The real is the x values and the imaginary are the y-values. Basically I would like to export the data to an excel spreadsheet with one column with the biasing voltages across the drain/source and multiple columns for the current across the drain/source w/different biasing voltages applied. I'm getting "NaN' values in my spreadsheet and it's only giving me values for the last iteration. I've placed my write to spreadsheet function inside my nested while loop, but it's prompting me to save a file for each added index. Ideally, I would like to place headers in there as well. I've attached my VI as well. Any help would be much appreciated!
