2 channels sampled at 12-bit resolution 500 MS/s real-time sampling rate Variable frequency external clocking Up to 2 Gigasample dual-port memory Continuous streaming mode Low noise ±400 mV fixed input range • AlazarDSO oscilloscope software • • Software Development Kit supports ® ® C/C++, C#, Python, MATLAB , LabVIEW ® Support for Windows & Linux For new designs, please use ATS9353 Product Operating System 32-bit/64-bit Windows & 64-bit Linux AlazarTech ATS®9351 is an 8-lane PCI Express (PCIe x8), dual-channel, high-speed, 12-bit, 500 MS/s waveform digitizer card capable of streaming acquired data to PC memory at rates up to 1.6 GB/s or storing it in its deep on-board dual-port acquisition memory buffer of up to 2 Gigasamples. The main difference between ATS9351 and ATS9350 is that ATS9351 has a fixed gain input amplifier that allows analog signals to be captured with a higher signal to noise ratio compared to ATS9350 Target customers for ATS9351 are those who have control over the output amplitude of their sensor and can match it to the full scale input range of ATS9351. Up to 2 Giga samples in single channel mode Applications Optical Coherence Tomography (OCT) Ultrasonic & Eddy Current NDT/NDE Radar/RF Signal Recording & Analysis Terabyte Storage Oscilloscope High-Resolution Oscilloscope Lidar Spectroscopy Digital Down Conversion (DDC) Multi-Channel Transient Recording For customers who need variable input gain, we recommend using the ATS9350. Optional variable frequency external clock allows operation from 500 MHz down to 2 MHz, making ATS9351 an ideal waveform digitizer for OCT applications. ATS9351 is supplied with AlazarDSO software that lets the user get started immediately without having to go through a software development process. Users who need to integrate the ATS9351 in their own program can purchase a software development kit, ATS-SDK, for C/C++, C#, Python, MATLAB, LabVIEW for both Windows and Linux operating systems. All of this advanced functionality is packaged in a low-power, half-length PCI Express card.

500 MS/s 12-Bit PCIe OEM Digitizer PCI Express Bus Interface ATS9351 interfaces to the host computer using an 8-lane PCI Express bus. Each lane operates at 2.5 Gbps. PCIe bus specification v1.0a and v1.1 are supported. According to PCIe specification, an 8-lane board can be plugged into any 8-lane or 16-lane slot, but not into a 4-lane or 1-lane slot. As such, ATS9351 requires at least one free 8-lane or 16-lane slot on the motherboard. The physical and logical PCIe x8 interface is provided by an on-board FPGA, which also integrates acquisition control functions, memory management functions and...

500 MS/s 12-Bit PCIe OEM Digitizer FPGA-Based FFT Processing It is possible to do real-time FFT signal processing using the on-board FPGA. Note that only one input can be processed. NPT AutoDMA is designed specifically for these applications. By only storing post-trigger data, the memory bandwidth is optimized and the entire onboard memory acts like a very deep FIFO. TRIGGER INPUT(S) CAPTURE Up to 2048-point FFT length is supported. A user programmable complex windowing function can be applied to the acquired data before FFT calculation. The complex FFT output is converted to magnitude in single...

500 MS/s 12-Bit PCIe OEM Digitizer Continuous AutoDMA can easily acquire data to PC host memory at the maximum sustained transfer rate of the motherboard without causing an overflow. This is the recommended mode for very long signal recording. What makes this very powerful is the fact that most modern CPUs have multiple cores, which can be used to do real-time signal processing using parallel processing principles. Triggered Streaming AutoDMA If your algorithm can be written to take advantage of parallel processing, this may be a very cost-effective solution for signal processing applications....

500 MS/s 12-Bit PCIe OEM Digitizer This proprietary software mechanism is called Async DMA (short for Asynchronous DMA). A number of data buffers are posted by the application software. Once a data buffer is filled, i.e. a DMA has been completed, ATS9351 hardware generates an interrupt, causing an event message to be sent to the application so it can start consuming data. Once the data has been consumed, the application can post the data buffer back on the queue. This can go on indefinitely. One of the great advantages of Async DMA is that almost 95% of CPU cycles are available for data processing,...

500 MS/s 12-Bit PCIe OEM Digitizer clocks without requiring the use of a dummy clock in the source. AlazarDSO Software ATS9351 is supplied with the powerful AlazarDSO software that allows the user to setup the acquisition hardware and capture, display and archive the signals. The Stream-To-Memory command in AlazarDSO allows users to stream a large dataset to motherboard memory. AlazarDSO software also includes powerful tools for benchmarking the computer bus and disk drive. Software Development Kits AlazarTech provides an easy-to-use software development kit for customers who want to integrate...

500 MS/s 12-Bit PCIe OEM Digitizer ATS-GPU-OCT is the optional OCT Signal Processing library for ATS-GPU. It contains floating-point FFT routines that have also been optimized to provide the maximum number of FFTs per second. Kernel code running on the GPU can do zero-padding, apply a windowing function, do a floating-point FFT, calculate the amplitude and convert the result to a log scale. It is also possible to output phase information. FFTs can be done on triggered data or on continuous gapless stream of data. It is also possible to do spectral averaging. Our benchmarks showed that it was...

500 MS/s 12-Bit PCIe OEM Digitizer Export Control Classification According to the Export Controls Division of Government of Canada, ATS9351 is currently not controlled for export from Canada. Its export control classification is N8, which is equivalent to ECCN EAR99. ATS9351 can be shipped freely outside of Canada, with the exception of countries listed on the Area Control List and Sanctions List. Furthermore, if the end-use of ATS9351, in part or in its entirety, is related to the development or deployment of weapons of mass destruction, AlazarTech is obliged to apply for an export permit.
