Analogue signals acquired at streaming
speeds
New from Datel is a fast analogue input board with a fully streaming architecture which collects samples without stopping the A/D convertor sample clock.
Among fast analogue input boards, fully streaming architecture which collects samples without stopping the A/D convertor sample clock, is still uncommon Some products must stop sampling when the onboard memory becomes full

Novel regulation makes dual DC/DCs more flexible
Datel's new BWR-5/3.3, 33W Series mixed-voltage, dual-output (3.3 and 5V) DC/DC convertors feature a novel output structure that does not limit output current in the traditional manner.
More current from industry-standard convertors
Datel's new USN Series D5 SIPs are nonisolated DC/DC convertors that accept a 5V input (4.5 to 5.5V input range) and deliver 1.5, 1.8, 2.5 or 3.3V outputs at either 8 or 10A.
But combining continuous A/Ds with a dual-channel streaming analogue output section (D/A) is extremely rare.
Datel's new wideband PCI-4174 board for desktop PCI computers handles both tasks simultaneously with ease.
The product addresses a wealth of high performance analogue signal processing, FFT and DSP applications.

3U Compact PCI bus with 32bit interface
Packaged on a diminutive 101.6 x 158.75mm board, Datel's new CPCI-510P includes a number of high-performance features for analogue signal processing applications on the Compact PCI bus.
Using "convertor per channel" architecture, both the four-channel A/D and two-channel D/A sections sample data exactly in parallel and are ideal for wide-bandwidth signal storage or playback of gigabytes between network, huge memory or disk.
Acting as a temporary PCI bus master, the PCI-417A then blasts the A/D signals via the onboard DMA controller to the user's buffer without loading the host CPU.
The PCI-417A accomplishes this using two separate FIFO memory sections for the A/D and D/A convertors.
The A/D and D/A FIFOs are 8192 samples each or 256k samples optional for the A/Ds.
The four 10MHz A/Ds are configured on a pluggable analogue module with 32bit transfer.
+2.5V A/D-D/A ranges are offered with 0-5V selectable for the A/Ds.
The architecture enables phase-coherent sensor arrays such accelerometers, sonar and Doppler studies and multiple simultaneous radar channels.
The A/D section includes a novel digital marker input channel to correlate external events to analogue phenomena.
An onboard PCIbus interrupt system is fully integrated with the DMA controller, FIFO and local 16Msample data point counter.
The A/D section is clocked by an onboard programmable frequency synthesiser, crystal timebase or external sample clock.
Frame triggering uses either an onboard programmable timebase, external digital input or analogue level trigger.
Other onboard resources include a programmable 24bit digital input section to access discrete devices.
A full technical data sheet is available on Datel's website.
The PCI-417A1 is available with advanced C++ Windows software source code for developers (optional model PC-CDROMs,) to integrate any conceivable application.
The board includes an executable (binaries only) version of this software at no charge.
The system offers a high performance device driver, DLL library and GUI for Windows.
The PC-CDROM also includes ActiveX controls, Visual Basic examples and MS-DOS test sources.
