2 channels sampled at 8-bit resolution 50 MS/s simultaneous real-time sampling rate on each input 256 kilo samples of on-board acquisition memory per channel • AlazarDSO oscilloscope software • Software Development Kit supports ® ® C/C++, C#, Python, MATLAB , LabVIEW Support for Windows & Linux For new designs, please use ATS9130 Product Operating System AlazarTech ATS®850 is a dual-channel, 8 bit, 50 MS/s waveform digitizer card for PCI bus, capable of storing up to 256 kilo samples per channel of acquired data in its on-board memory. It should be noted that it is not possible for ATS850 acquisition memory to be dual-ported. For applications that require dual-port memory, consider using ATS860. Applications Motor Winding Testing Ultrasonic & Eddy Current NDT/NDE Low Cost Oscilloscope Spectroscopy Multi-Channel Transient Recording For scientific customers who want to record multiple analog inputs simultaneously, ATS850 offers multichannel data acquisition systems of up to 8 channels. ATS850 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 ATS850 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 card available. Motherboards with PCI slots are becoming increasingly difficult to source. Customers should, therefore, consider using the ATS9130 PCIe waveform digitizer, which provides 12-bit, 50 MS/s dual-channel sampling, and dual-port memory.

50 MS/s 8-Bit PCI Digitizer Dual-port memory, which allows streaming of very large gapless data across the PCIe bus for storage in fast disk drives, is not available on ATS850. Analog Input An ATS850 features two analog input channels with extensive functionality. Each channel has 25 MHz of full power analog input bandwidth. With software-selectable attenuation, you can achieve an input voltage range of ±20 mV to ±20 V. Attenuating probes (sold separately) can extend the voltage range even higher. Software-selectable AC or DC coupling further increases the signal measurement capability....

50 MS/s 8-Bit PCI Digitizer A Leader/Follower system is guaranteed to sample simultaneously across all channels in that system. Triggering is also guaranteed to be simultaneous across all digitizers in the system. Optional External Clock While the ATS850 features a low-jitter, high-reliability 50 MHz crystal oscillator as the source of the timebase system, there may be occasions when digitizing has to be synchronized to an external clock source. ATS850 External Clock option provides a BNC input for a TTL compatible external clock signal with a frequency between 50 MHz and 1 MHz. This clock...

50 MS/s 8-Bit PCI Digitizer Based on a minimum annual business commitment, the Linux driver source code license (order number ATS850-LINUX) may be granted to qualified OEM customers for a fee. For release of driver source code, a Non-Disclosure Agreement must be executed between the customer’s organization and AlazarTech. All such source code disclosures are made on an as-is basis with limited support from the factory. Technical Support AlazarTech is known for its world-class technical support. Customers receive free technical support on hardware products that are under warranty. AlazarTech...
