Precision Current Input With Well-Defined Current Limiting for Extreme Environment Applications

NASA’s Jet Propulsion Laboratory, Pasadena, California Wide temperature and extreme environment electronics are crucial to future missions. These missions will not have the weight and power budget for heavy harnesses and large, inefficient warm boxes. In addition, extreme environment electronics, by their inherent nature, allow operation next to sensors in the ambient environment, reducing noise and improving precision over the warm-box-based systems employed today.

Data Acquisition Board

Measurement Computing (Norton, MA) offers the USB-2020 high-speed, two-channel data acquisition board that provides simultaneous sampling at rates up to 20 MS/s per channel. Users can sample data from both channels at an overall rate of 40 MS/s to the 64-megasample onboard memory, or continuously stream data to a host computer at up to 8 MS/s for one or both channels over a high-speed USB connection. Each channel has its own A/D converter for simultaneous sampling to eliminate channel skew and ensure that phase information between channels is maintained.
