Sample Bandwidth Rate AlazarTech ATS®9120 is a dual-channel, 12-bit, 20 MS/s waveform digitizer card capable of storing up to 8 Million samples per channel of acquired data in its on-board memory or streaming acquired data to PC memory. ATS9120 is a single-lane PCI Express (PCIe x1) Gen 1 card, which supports up to 200 MB/s bus throughput. Users can capture data from one trigger or a burst of triggers. Users can also stream very large datasets continuously to motherboard memory or hard disk. ATS9120 PCI Express digitizers are an ideal solution for cost sensitive OEM applications that require a digitizer to be embedded into the customer’s equipment. Applications Optical Coherence Tomography (OCT) Ultrasonic & Eddy Current NDT/NDE Motor Winding Testing Radar/RF Signal Recording & Analysis High-Resolution Oscilloscope Lidar Spectroscopy Multi-Channel Transient Recording ATS9120 is supplied with AlazarDSO oscilloscope software that lets the user get started immediately without having to write any software. Users who need to integrate the ATS9120 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 system. All of this advanced functionality is packaged in a low-power, half-length PCI Express card.

20 MS/s 12-Bit PCIe Digitizer PCI Express Bus Interface ATS9120 interfaces to the host computer using a 1-lane PCI Express bus, operating at 2.5 Gbps. According to PCIe specification, a 1-lane board can be plugged into any PCIe slot. ATS9120 requires at least one free slot on the motherboard. Electrically, ATS9120 is compatible with Gen 1, Gen 2, and Gen 3 slots. The physical and logical PCIe x1 interface is provided by an on-board FPGA, which also integrates acquisition control functions, memory management functions and acquisition datapath. This very high degree of integration maximizes product...

20 MS/s 12-Bit PCIe Digitizer No Pre-Trigger (NPT) AutoDMA Many ultrasonic scanning and medical imaging applications do not need any pre-trigger data: only post-trigger data is sufficient. NPT AutoDMA is designed specifically for these applications. By only storing post-trigger data and using an FPGA FIFO as temporary storage, data throughput is optimized. 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. Triggered Streaming AutoDMA Triggered...

20 MS/s 12-Bit PCIe Digitizer Triggering The ATS9120 is equipped with sophisticated analog and digital triggering options, such as programmable trigger thresholds and slope on any of the input channels or the External Trigger input. While most oscilloscopes offer only one trigger engine, ATS9120 offers two trigger engines (called Engines J and K). This allows the user to combine the two engines using a logical OR operand. The user can specify the number of records to capture in an acquisition, the length of each record and the amount of pre-trigger data. A programmable trigger delay can also...

20 MS/s 12-Bit PCIe Digitizer The Stream-To-Memory command in AlazarDSO allows users to stream a large dataset to motherboard memory. 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. AlazarDSO software also includes powerful tools for benchmarking the computer bus and disk drive. ATS-GPU-NUFFT is an extension of ATS-GPU-OCT that allows non-uniform FFTs to be performed on data acquired uniformly in time domain using a fixed sampling rate. For SS-OCTs where the wavelength does not vary linearly...
