The goal of the present work was to upgrade the data acquisition system (DAS) in the high-speed building of the Turbopropulsion Laboratory (TPL) and to develop a high-speed acquisition capability for pressure measurements for both the TPL and the new Gas Dynamics Laboratory (GDL) . Based on the use of the Hewlett Packard HP9000 Series 300 Computer as the system controller, a 96-channel high-speed pressure DAS was developed using Scanivalve ZOC-14 modules and a CALSYS2 000 calibrator. The system allowed acquisition times for current wind-tunnel experiments to be revised from four minutes to eleven seconds. Also, new software was written to acquire data from existing rotary pneumatic Scanivalves and HP-IB compatible instrumentation so that all other existing acquisition capabilities were maintained in both laboratories.
