2 channels sampled at 14-bit resolution 125 MS/s simultaneous real-time sampling rate on each input Up to 128 Million samples of on-board acquisition memory per channel Asynchronous DMA device driver 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®9146 is a dual-channel, 14-bit, 125 MS/s waveform digitizer card capable of storing up to 128 Million samples per channel of acquired data in its on-board memory or streaming acquired data to PC memory. ATS9146 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. ATS9146 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 Radar/RF Signal Recording & Analysis Terabyte Storage Oscilloscope High-Resolution Oscilloscope Lidar Spectroscopy Multi-Channel Transient Recording ATS9146 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 ATS9146 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.

125 MS/s 14-Bit PCIe Digitizer PCI Express Bus Interface ATS9146 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. ATS9146 requires at least one free slot on the motherboard. Electrically, ATS9146 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...

125 MS/s 14-Bit PCIe Digitizer NPT AutoDMA is designed specifically for these applications. By only storing post-trigger data, the memory bandwidth is optimized. Triggered Streaming AutoDMA Triggered Streaming AutoDMA is virtually the same as Continuous mode, except the data transfer across the bus is held off until a trigger event has been detected. START CAPTURE INPUT(S) CAPTURE NPT AutoDMA buffers do not include headers, so it is not possible to get trigger time-stamps. More importantly, a BUFFER_OVERFLOW flag is asserted if the on-board memory overflows, i.e. the amount of memory that...

125 MS/s 14-Bit PCIe Digitizer J and K). This allows the user to combine the two engines using a logical OR operand. There are three types of External Clock supported by ATS9146. These are described below. 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. Fast External Clock A new sample is taken by the on-board ADCs for each rising (or falling) edge of this External Clock signal. A programmable trigger delay can also be set by the user. This is very useful for capturing the signal of interest in a...

125 MS/s 14-Bit PCIe Digitizer RoHS Compliance ATS9146 units are fully RoHS compliant, as defined by Directive 2015/863/EU (RoHS 3) of the European Parliament and of the Council of 31 March 2015 on the restriction of the use of certain hazardous substances in electrical and electronic equipment. All manufacturing is done using RoHS-compliant components and lead-free soldering. On-Board Monitoring Adding to the reliability offered by ATS9146 are the on-board diagnostic circuits that constantly monitor over 15 different voltages, currents and temperatures. LED alarms are activated if any of...
