16bit  PCI waveform digitizer

AlazarTech has announced the release of ATS660, touted to be the world's fastest 16bit PCI waveform digitizer designed for OEMs and R&D customers involved in RF signal analysis, biomedical imaging, ultrasonics, OCT, radar, lidar, among others.

According to the company, the new device offers two simultaneous analog inputs that can each be sampled at rates up to 125MSps (one 16bit, 125MSps ADC per channel), providing SNR in excess of 73dB. Each channel can have up to 128MS of on-board acquisition memory buffer. The unit occupies one half-length PCI slot.

The new waveform digitizer features a dual port acquisition memory that allows transfer of acquired data to PC memory without having to stop the acquisition session. The company claimed it knew no other waveform digitizer manufacturer offering dual port memory.

"With the ATS660, customers not only get the fastest and highest quality 16bit DAQ system, they also get the ability to transfer data to PC memory at very high speed without having to stop the acquisition," said Muneeb Khalid, AlazarTech's president. "This, combined with FPGA customization for filtering, FFT, etc., allows OEMs to deploy systems immediately, without having to build their own hardware."

The new waveform digitizers use FPGA-based digital electronics for control and data processing. The company's own HyperDisP display technology allows the full 128MS-long record to be displayed on a computer screen in a matter of seconds, said AlazarTech.

The on-board FPGA can also be customized for OEMs. Customization can include simple control functions, such as extra triggers or trigger enables, simple mathematical functions, such as averaging, and even complex DSP functions such as FIR filters, demodulation and FFT, the company explained.

The new digitizers come in two versionsthe ATS660-16M and ATS660-128Mpriced at $4,495 and $5,495, respectively. OEMs can integrate the PCI digitizers into their own systems using the Windows XP/2000/98SE-compatible ATS-SDK software development kit (SDK), priced at $325. This SDK includes sample programs written in C/C++ and VisualBASIC. Also available is a LabVIEW VI called ATS-VI, priced at $325. A Linux driver, ATS-Linux, is also available for $325 and supports kernel version up to 2.6.
