This document provides a quality assurance equipment measurement summary report. It details the purpose, scope, methodology, and results of measuring the accuracy and linearity of 31 LTX systems using a HP3458A standard voltage meter. Measurements from 2.5V to 5.4V on 26 sample parts were analyzed against tolerance guidelines to verify the equipment is operating within acceptable accuracy and precision limits established by standard operating procedures. Issues requiring further investigation or unacceptable results are identified. The next scheduled measurement system evaluation is also noted.
