Summary:

The Quality Assurance (QA) Department of Sandia National Laboratories is responsible to the Department of Energy for assurance that weapons remain functional throughout their stockpile life. To accomplish this, QA conducts laboratory system tests on the Sandia-designed components of the weapon system. Joint flight tests with the Department of Defense are also conducted. The data acquisition and processing system used to acquire and analyze test results was designed by the QA Systems Test Equipment Design Division. The acquisition systems are built around PDP 11/34 computers. There are six similar acquisition systems that collect data independently from many unique weapon testers. A test usually lasts several minutes. After the data are acquired, the system engineers are interested in seeing the results as soon as possible. The complete test analysis must be known before disassembling the test equipment and moving on to the next scheduled test. If anomalies were present, disassembling would compromise posttest trouble-shooting procedures. The analysis for each test is therefore performed on the acquisition machine immediately after each test and must be completed in as short a time as possible. The FORTRAN software package used to analyze the results of laboratory system tests is considered. How the software works, problems encountered when it was decided to double the number of data acquisition channels to analyze, and the solution to the problems arrived at by benchmarking the programs with optional equipment that could be added to the existing configuration are discussed.
