2 channels sampled at 12-bit resolution 1 GS/s real-time sampling rate Variable frequency external clocking Continuous streaming mode ±400 mV fixed input range • AlazarDSO oscilloscope software • Software Development Kit supports ® ® C/C++, C#, Python, MATLAB , LabVIEW Support for Windows & Linux Operating System 32-bit/64-bit Windows & 64-bit Linux Max. Sample Bandwidth Rate AlazarTech ATS®9371 is an 8-lane PCI Express Gen 3 (PCIe x8), dual-channel, high-speed, 12-bit, 1 GS/s waveform digitizer card capable of acquiring data into its on-board 8 GB memory or streaming acquired data to PC memory at rates up to 6.9 GB/s. It is also possible to do FPGA-based 4096-point FFT on acquired data. This is useful for Optical Coherence Tomography (OCT) related applications. There are two A/D converters on the ATS9371 board, each running at 1 GS/s. Unlike other products on the market, ATS9371 does not use interleaved sampling. Each input has its own 12-bit, 1 GSPS ADC chip. Applications Optical Coherence Tomography (OCT) Ultrasonic & Eddy Current NDT/NDE RF Signal Recording & Analysis Terabyte Storage Oscilloscope High-Resolution Oscilloscope Spectroscopy Multi-Channel Transient Recording Optional variable frequency external clock allows operation from 1 GHz down to 300 MHz (or 100 MHz for screened ATS9371 cards), making ATS9371 an ideal waveform digitizer for many applications. Users can capture data from one trigger or a burst of triggers. Users can also stream very large datasets continuously to PC memory or hard disk. ATS9371 is supplied with AlazarDSO software that lets the user start data acquisition immediately, without having to go through a software development process. Users who need to integrate the ATS9371 in their own program can purchase a software development kit, ATS-SDK, for C/C++, C#, Python, MATLAB, and LabVIEW for both Windows and Linux operating systems. All of this advanced functionality is packaged in a low power, half-length PCI Express Gen 3 card. Page 1

1 GS/s 12-Bit PCIe Gen3 Digitizer PCI Express Gen 3 Bus Interface ATS9371 interfaces to the host computer using an 8-lane PCI Express bus. Each lane operates at 8.0 Gbps (Gen 3). 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, ATS9371 requires at least one free 8-lane or 16-lane slot on the motherboard. ATS9371 is fully compatible with motherboards of all generations of PCI Express (Gen 1, Gen 2 or Gen 3). At run-time, ATS9371 and the motherboard negotiate the appropriate link speed and width. The...

1 GS/s 12-Bit PCIe Gen3 Digitizer The complex FFT output is converted to magnitude in single-precision floating-point format. A logarithmic output is also available. It is also possible to DMA both frequency and time domain data. This allows users to verify FPGA-based FFT operation during algorithm development. ATS9371 can perform 250,000 4096-point FFTs per second. FPGA-based FFT is ideal for customers in the Optical Coherence Tomography (OCT) field. FPGA-Based Digital Signal Processing In addition to providing the bus interface and managing the acquisition engine, ATS9371’s on-board FPGA is...

1 GS/s 12-Bit PCIe Gen3 Digitizer Note that it is the user application’s responsibility to unpack the data. Also note that NPT Footers are not available in Data Packing Mode. START CAPTURE TRIGGER INPUT(S) CAPTURE A BUFFER_OVERFLOW flag is asserted only if the entire on-board memory is used up. As in Continuous mode, the amount of data to be captured is controlled by counting the number of buffers acquired. Acquisition is stopped by an AbortCapture command. Triggered Streaming AutoDMA can easily acquire data to PC host memory at the maximum sustained transfer rate of the motherboard without causing...

1 GS/s 12-Bit PCIe Gen3 Digitizer Fast External Clock A new sample is taken by the on-board ADCs for each rising edge of this External Clock signal. In order to satisfy the clocking requirements of the ADC chips being used, Fast External Clock frequency must always be higher than 300 MHz and lower than 1 GHz. For customers whose external clocks may go lower than 300 MHz during the acquisition, it is possible to have AlazarTech screen the ATS9371 boards for external clock operation down to 100 MHz (Order number ATS9371-006) This is the ideal clocking scheme for OCT applications. 10 MHz Reference...

1 GS/s 12-Bit PCIe Gen3 Digitizer ATS-GPU ATS-GPU is a software library developed by AlazarTech to allow users to do real-time data transfer from ATS9371 to a GPU card at rates up to 6.9 GB/s. Interfacing waveform digitizers to GPUs involves creating a software mechanism to move data from one to the other and back to user buffers. The standard techniques used most often can get the job done, but feature very low data throughput due to software overheads. AlazarTech designed ATS-GPU to eliminate this software bottleneck so that data can be moved from AlazarTech digitizers to GPUs and from GPUs...

1 GS/s 12-Bit PCIe Gen3 Digitizer AlazarTech digitizers come with a standard one (1) year parts and labor warranty. This warranty can be extended for a fee (more information can be found in the Extended Warranty section below). If your waveform digitizer is out of warranty, you will not be eligible for free technical support on AlazarTech hardware or software products and you will need to purchase technical support hours (order number SUPPORT-HR5) to obtain assistance. In addition, any necessary repairs to your out-ofwarranty hardware products will carry a minimum bench charge. Extended Warranty...
