PCIAD850 / PCIAD1650
Multi-Channel Analog to Digital Converter Board with Simultaneous Acquisition
PCIAD850 and PCIAD1650 are analog to digital data converter boards with simultaneous acquisition. The PCIAD850 supports 8 channels while the PCIAD1650 supports16 channels. At each trigger event (software trigger or external trigger), all the channels will simultaneously convert the analog signals to digital data with user selected post trigger delay and waveform length. Other programmable parameters include sampling rate, trigger source, trigger rate, gain, DC offset, low and high pass filters. Both boards feature user-selectable 8 or 10-bit resolution and up to 50 mega samples per second.
Multiple boards can be installed in the same computer for a data acquisition system with more than one hundred channels. With one board set as the master and remaining set to slave mode, all channels on the slave boards will start taking data upon receiving a trigger signal from the master board. The jitter between channels is less than 2 nanoseconds.
The gain adjustment can be calibrated to a specified range in the factory. It can also be adjusted for ultrasonic testing purposes.
Working with US Ultratek's PHA8(T) and PHA16(T), the PCIAD850 and PCIAD1650 boards become a simultaneous multi-channel ultrasonic testing system with phased array capabilities. The phased array system has both single pulse and tone burst pulse capabilities.
The optional distance amplitude gain (DAC) sets various gains at different times during the acquisition. This is useful for the ultrasonic inspections.
Up to 2 encoder counters can be added to the board to enable position-based data acquisition.
