Use these Igor Pro 3 procedures to load the *.WFA ASCII files created by software associated with Tektronix's DSA601 and DSA602A digital signal analyzers. The procedures aren't very fast, but they DO work. To use the procedures... Move to your User Procedures folder: Load Tek WFA File File Name Utilities Keyword-Value Generalized Use the LoadTekWFAFile() macro to select a file to load and display. If you move this file to your Igor Procedures folder: Tek WFA Drag & Drop then you can drag .WFA files onto the Igor icon and they'll automatically be loaded and displayed.
