25 April 2006 -- Available now from ICS Sensor Processing, part of Radstone Embedded Computing, the eight-channel ICS-1745 high speed acoustic ADC board is designed for military sonar applications - including littoral and anti-mine systems - and vibration analysis. Characterised by its 3U CompactPCI small form factor, the ICS-1745 features eight channels of high frequency acoustic analogue input and onboard signal conditioning with programmable gain. ICS already offers the industry's broadest range of data acquisition products in the 6U VME and PCI form factors.
'One of our key goals is to be responsive to customer needs, and the launch of the ICS-1745 addresses our customers' growing requirement for solutions that are constrained by space, weight and power', said Scott Hames, Director of Product Management at ICS Sensor Processing.
'By migrating our market-leading high speed acoustic technology to the 3U cPCI form factor, we've achieved substantial reductions in size and weight, but maintained the high performance customers expect from ICS'.
The ICS-1745's eight channels use the Analog Devices AD9260 16bit high speed oversampled A/D convertor with buffer memory, delivering 2.5Msample/s.
Onboard signal conditioning further contributes to enabling the ICS-1745 to be at the heart of a compact solution, obviating the requirement for external signal conditioning logic.
With a maximum bandwidth of 1.25MHz and onboard signal conditioning, the ICS-1745 supports four input voltage ranges (20, 2, 0.2 and 0.02V peak-peak differential) and 8Mbyte of memory in two banks.
All channels sample synchronously, with very close phase match between channels.
Through software, the user can specify one of four input voltage ranges.
The anti-alias cutoff filter frequency is fixed at 1.25MHz for the standard product: other frequencies can be supplied on request.
Differential analogue input is provided via the front panel, while a second connector on the front panel provides for multiple board synchronisation for systems requiring high channel counts.
Software drivers are available for Windows and Linux operating systems.
