SCALABLE
The PXIe board is compatible with
National Instruments’ card cages
and several other brands. You
can add as many boards as you
like, making it perfect for multi-
channel system integration.
ULTRA-FAST
The FPGA and memory
architecture was designed
specifically for high-throughput
ultrasound applications, offering
sustained bandwidths up to 90
MB/sec and PRFs in excess of
30kHz.
IDEAL FOR UT
The board’s analog front-end is
suited for ultrasound applications:
gain, TCG, AC/DC coupling,
fast gate detection, etc. The
firmware and software are field-
upgradeable.
READY FOR CUSTOMIZATION
Both firmware and software are
customizable to modify or add a
specific functionality. PRAGMA
can provide all the engineering.
