AT-A2150C

National Instruments AT-A2150C / AT-A2150S Dynamic Signal Acquisition Board
Features

• Four Channels of 16-bit
• 64-Times Over Sampling
• Conversion Rates of Up to 51.2kHz
• Equipped with Crystal Oscillators

The National Instruments AT-A2150C/AT-A2150S are dynamic signal acquisition boards for the PC. These boards have 4 channels of 16-bit, simultaneously sampled analog input with 64-times over sampling delta-sigma modulating ADCs and digital antialiasing filters for extremely high-accuracy data acquisition. The AT-A2150C/AT-A2150S can interface to the RTSI bus. This interface includes 256-word FIFO buffers for smooth data flow out of the board. This allows sampling clock synchronization between multiple AT-A2150 boards for simultaneous sampling on more than 4 channels.

The AT-A2150C/AT-A2150S are useful for digitizing signals with bandwidths of 22 kHz or less. These boards can be used with the following applications: acoustics and speech research, audio signal processing and analysis, sonar, audio workstations, and audio frequency test and measurement.

The AT-A2150C model is designed for full audio band measurements and for signal processing applications. This board is equipped with crystal oscillators for standard digital audio and digital signal processing frequencies.

The AT-A2150S is designed for speech and voiceband measurements and comes with crystal oscillators for speech applications.
