125 MS/s 4 channel PCIe Digitizer • 4 channels sampled simultaneously Up to 125 MS/s real-time sampling rate Up to 2 Gigasample dual-port memory Continuous streaming mode 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®9440 is an 8-lane PCI Express (PCIe x8), quad-channel, high-speed, 14-bit, 125 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. Each ATS9440 board has four Analog-to-Digital converter (ADC) chips that are clocked simultaneously using a low-jitter VCO to provide absolute synchronization. Up to 2 Gig in single channel mode Applications Optical Coherence Tomography (OCT) Ultrasonic & Eddy Current NDT/NDE Terabyte Storage Oscilloscope High-Resolution Oscilloscope Spectroscopy Multi-Channel Transient Recording SMB connectors are used to increase the I/O density on the back-panel of ATS9440. Up to four ATS9440 boards can be configured as a Leader/Follower system to create a simultaneous sampling system of up to 16 input channels. 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. ATS9440 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 ATS9440 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 card.

125 MS/s 4 channel PCIe Digitizer PCI Express Bus Interface ATS9440 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. By definition, ATS9440 is also compatible with PCI Express Gen 2. Infinite number of triggers can be captured by ATS9440, when it is operating using dual-port memory. In between the multiple triggers being captured, the acquisition system is re-armed by the hardware within 256 sampling clock cycles. According to PCIe specification, an 8-lane board can be plugged into any 8-lane...

125 MS/s 4 channel PCIe Digitizer It should be noted that some motherboards may behave unexpectedly. For example, one customer purchased a P6T6 motherboard (instead of P6T7) and found that the throughput was limited to approximately 800 MB/s because P6T6 only supports 4-lane PCI Express connection, even though it uses the same x58 chipset. Traditional AutoDMA In order to acquire both pre-trigger and post-trigger data in a dual-ported memory environment, users can use Traditional AutoDMA. TRIGGER NPT AutoDMA can easily acquire data to PC host memory at the maximum sustained transfer rate of the...

125 MS/s 4 channel PCIe Digitizer 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 an overflow. This is the recommended mode for RF signal recording that has to be started at a specific time, e.g. based on a GPS pulse. Leader/Follower Systems Users can create...

125 MS/s 4 channel PCIe Digitizer Timebase ATS9440 timebase can be controlled either by onboard low-jitter VCO or by optional External Clock. On-board low-jitter VCO uses an on-board 10 MHz TCXO as a reference clock. Optional External Clock While the ATS9440 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. Dummy Clock Switchover OCT applications require interfacing the ATS9440 to a variable clock frequency (called k-clock) from a swept-source laser. In most cases, k-clock...

125 MS/s 4 channel PCIe Digitizer On-Board Monitoring Adding to the reliability offered by ATS9440 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 ATS9440 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...
