Portfolio of work : High Speed Acoustic data acquisition cards in different format
In order to interface single board computers and DSP engines to RF equipment used in spectrum monitoring The PCI2CH24BIT is a high-resolution wide band acoustic data acquisition card in PCIe form factor which enables a variety of acoustic and ultrasound signal processing functions, including active or passive sonar, vibration analysis, geophysics, and other test and measurement applications. The card provides two “high speed” (2.5MSPS) analog input channels, and four “low speed” (144kSPS) channels, which it converts to digital data with 24-bit resolution. Anti-aliasing inherent in the Sigma-Delta converters simplifies analog signal conditioning elsewhere in the signal path. The analog front end includes adjustable gain and two pole anti-alias filtering. All other processing is performed using the on-board FPGA resources
