Abstract

A new software library for The ALMA Front End Test and Measurement System (FETMS) will be implemented at the NRAO Technology Center (NTC) to test new front end systems. This library will ensure that these front end systems meet noise temperature specifications and IF output power spectrum specifications, allowing optimal signal-to-noise ratios (SNR) to be made with the receivers. The library is written in PHP and is used to find, analyze, and display test data from FETMS measurements database. It features structured interfaces for simple communication between tests, flexible database retrieval to minimize computation time, universal data structures which utilize the PHP array features to allow for ease in data manipulation, and an adaptable plotter class that gives the user a simple module to plot their data. These features will allow for easier use, quicker maintenance, and more timely upgrades. This library is now running on the FETMS at the NTC and future versions will include more specification test options and the removal of possible bugs.
