14-Bit PCI Digitizer Family Hits 125 MS/s, Offers Dual Port Memory And The Lowest Price In Its Class
Montreal, CanadaAlazarTech, the manufacturer of high performance, low cost PC Based Instruments, today announced the launch of the ATS460 family of 14 bit PCI waveform digitizers capable of sampling two simultaneous analog inputs at rates up to 125 MS/s on each channel. This new PCI digitizer family is targeted for the needs of OEM customers and applications involving ultrasonic imaging and inspection, medical imaging, telecommunication test, manufacturing test and scientific research and development.
The ATS460 offers simultaneous sample rate up to 125 MS/s on two fully programmable analog inputs per digitizer card, one 125 MSPS 14 bit ADC per input, 8 MegaSamples of on-board memory and ability to synchronize up to 8 digitizers to create a 16 channel 125 MS/s simultaneous sampling system.
"Customer feedback suggested that the market needed a well priced, high resolution PCI digitizer with the ability to acquire signals with very high PRF (Pulse Repeat Frequency) for applications in ultrasonics, radar and medical imaging," stated Muneeb Khalid, President of AlazarTech. "We responded by following our corporate strategy of providing 'More For Less.' We designed the low-cost ATS460 family that uses the fastest available 14-bit monolithic ADCs and also created a dual-port memory sub-system for signal storage that maximizes PRF."
Traditionally, users had to capture data into a digitizer's on-board memory and then transfer it to PC memory using DMA. No acquisition was possible while data transfer was taking place and vice-versa. This scheme created a bottleneck in terms of Pulse Repeat Frequency, as the re-arm time of the digitizer combined with Windows related software overheads placed a ceiling on how many triggers could be captured in a given period of time.
Using AlazarTech's optional dual-port memory that provides up to 8 Megasamples of on-board storage per channel, very fast PRF rates are now possible, as acquired data can be transferred to host PC memory while acquisition is taking place. Customers should see an average improvement of as much as 300% in the PRF that they can achieve using the ATS460 family.
ATS460 PCI digitizer family provides independently programmable input ranges from +/- 40 mV to +/- 20V, AC/DC coupling and 50-ohm/1-Mohm impedance on each of its two channels. The sampling rate is also programmable from 125 MS/s down to 1 KS/s.
Users can also capture transient signals from rapidly occurring triggers by using Multiple Record mode that allows both pre- and post-trigger capability. A 40-bit time stamp allows users to record the occurrence of each trigger event relative to all other triggers in a given session.
An on-board high performance FPGA forms the heart of the ATS460 and can be customized for specific applications, such as Digital Down Conversion (DDC), Signal Averaging, Hardware FFT etc.
The ATS460 digitizers are accompanied by HyperDisP powered API Panel software that allows the user to set up the digitizer, acquire signals and view and store them without any software programming. AlazarTech's HyperDisP technology allows the display of very long data records at lightning fast speeds, even under Windows or Linux environment.
OEMs can integrate the ATS460 PCI digitizers into their own systems very easily using the Windows XP/2000/98SE compatible ATS-SDK Software Development Kit. This SDK includes sample programs written in C/C++ and VisualBASIC. A high performance LabVIEW VI, called ATS-VI, is also available. A Linux driver, ATS-Linux, is also available and supports kernel version up to 2.4.
