Variable frequency external clocking Continuous streaming mode ±400 mV fixed input range Optional 1.9 GHz wideband upgrade ® • 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 AlazarTech ATS®9373 is an 8-lane PCI Express Gen 3 (PCIe x8), single or dual-channel, high-speed, 12-bit, 4 GS/s or 2 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 ATS9373 board, each running at 2 GS/s. ATS9373 uses interleaved sampling (DES mode) to achieve 4 GS/s sampling. 4/2 Gigasamples in single/dual channel mode 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 2 GHz down to 500 MHz when using DES mode and from 2 GHz down to 300 MHz when operating in non-DES mode (or 100 MHz for screened ATS9373 cards), making ATS9373 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. ATS9373 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 ATS9373 in their own program can purchase a software development kit, ATSSDK, 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

4 GS/s 12-Bit PCIe Gen3 Digitizer PCI Express Gen 3 Bus Interface ATS9373 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, ATS9373 requires at least one free 8-lane or 16-lane slot on the motherboard. ATS9373 is fully compatible with motherboards of all generations of PCI Express (Gen 1, Gen 2 or Gen 3). At run-time, ATS9373 and the motherboard negotiate the appropriate link speed and width. The...

4 GS/s 12-Bit PCIe Gen3 Digitizer FPGA-Based Digital Signal Processing In addition to providing the bus interface and managing the acquisition engine, ATS9373’s on-board FPGA is also used for digital signal processing, such as Fast Fourier Transforms. 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 Note that a DMA is not started until (RecordsPerBuffer +1) number of records (triggers) have been acquired and written to the on-board...

4 GS/s 12-Bit PCIe Gen3 Digitizer BUFFER_OVERFLOW flag is asserted only if the entire on-board memory is used up. post the data buffer back on the queue. This can go on indefinitely. The amount of data to be captured is controlled by counting the number of buffers acquired. Acquisition is stopped by an AbortCapture command. One of the great advantages of Async DMA is that almost 95% of CPU cycles are available for data processing, as all DMA arming is done on an eventdriven basis. Continuous AutoDMA can easily acquire data to PC host memory at the maximum sustained transfer rate of the motherboard...

4 GS/s 12-Bit PCIe Gen3 Digitizer Timebase ATS9373 timebase can be controlled either by onboard low-jitter VCO or by optional External Clock. On-board low-jitter VCO uses a 10 MHz TCXO as a reference clock. Clock buffers used feature less than 76 fsRMS additive jitter. Optional External Clock While the ATS9373 features low-jitter VCO and a 10 MHz TCXO as the source of the timebase system, there may be occasions when digitizing has to be synchronized to an external clock source. AlazarTech’s OCT Ignore Bad Clock technology allows safe operation with these out-of-specification clocks without requiring...

4 GS/s 12-Bit PCIe Gen3 Digitizer On-Board Monitoring Adding to the reliability offered by ATS9373 are the on-board diagnostic circuits that constantly monitor over 20 different voltages, currents and temperatures. LED alarms are activated if any of the values surpass the limits. AlazarDSO Software ATS9373 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...
