Rocket Steering Motor Test System Summary: The customer required a totally integrated system which can be configured without any prior software knowledge and which is expandable to at least 250 channels . Because of the hazardous nature of the test, the host computer needed to be some distance from the data system.

This VXI-based data system is used to control hazardous test operations and to acquire data during the test. It tests rocket steering systems. The initial system acquires 36 channels of data, which includes 10 bridge-type strain inputs at 20 kHz, 10 voltages at 20 kHz, 16 thermocouples at 100 Hz, and also includes a 2-channel function generator, 16 relay outputs and 16 digital inputs. Because of the hazardous nature of the tests, the system needed to transmit data over a distance of at least 1000 feet, with an overall data transfer rate of 600 kbytes/s. Our 2962/V160 Grand Interconnect™ can transmit data up to 2 kilometers (6562 feet), and the overall system can easily meet the 600 kbyte/s. requirement. The complete DAQ Director-based system was integrated at our factory.
