The customer required VXI-based data acquisition systems as part of a test cell upgrade program for a major manufacturer of jet aircraft engines. These VXI data acquisition systems must meet the customer's requirements for high accuracy, high throughput and the ability to preserve existing application software while providing state-of-the-art replacements for existing systems.
KineticSystems provided VXI-based data acquisition systems that met the customer's stated requirements.
The VXI-based data acquisition test system includes 1,500 channels of signal conditioning and analog-to-digital conversion as well as frequency counter channels, digital-to-analog converter channels and discrete outputs. Each data system includes three VXI mainframes interconnected by our high-throughput fiber-optic Grand Interconnect (GI). The GI and its list memory serve as the data engine for this system. Data is acquired at 1000 Hz, 200 Hz and 10 Hz. An overall accuracy of several microvolts is required for the analog input channels. Our V243 and V208 modules, which include on-line calibration, meet this requirement.
A key strategy in these systems involves the use of reflective memory. The reflective memory is used as a data highway to other test stand systems. This can be considered to be common memory pool of data. With this configuration, other computer platforms also have access to the same engine data in a real-time mode. The reflective memory allows the customer to maintain their current application software, which has been developed over many years.
