Software for Time and Frequency Data Analysis

AMTyF Software (Analisis de Mediciones de Tiempo y Frecuencia), developed by Francisco J. Jimenez Tapia of CENAM with the menus in Spanish. This software is useful for the graphing and analysis of frequency and phase data, and also for stability analysis using the Allan deviation. It runs on Windows XP and earlier versions of Windows, but not yet with Vista. To install the software, extract all of the contents of the ZIP file to a folder on your hard drive, and then run the SETUP.EXE program.
