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 Optional dual-port memory for data streaming • AlazarDSO oscilloscope software • • Software Development Kit supports ® ® C/C++, C#, Python, MATLAB , LabVIEW ® Support for Windows & Linux For new designs, please use ATS9146 Product Operating System AlazarTech ATS®460 is a state of the art, dual-channel, high-resolution, 14 bit, 125 MS/s waveform digitizer card for PCI bus, capable of storing up to 128 Million samples per channel of acquired data in its on-board memory. With optional dual-port memory and fully asynchronous DMA, ATS460 allows users to build Windows or Linux based real-time data acquisition systems. Users are allowed to read acquired data even while the acquisition is in progress, including the ability to stream data to disk at rates up to 50 MS/s on one channel and 25 MS/s on 2 channels, simultaneously. Applications Optical Coherence Tomography (OCT) Ultrasonic & Eddy Current NDT/NDE Radar/RF Signal Recording Terabyte Storage Oscilloscope High-Resolution Oscilloscope Lidar Spectroscopy Multi-Channel Transient Recording For scientific customers who want to record multiple analog inputs simultaneously, ATS460 offers multichannel data acquisition systems of up to 8 channels. ATS460 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 ATS460 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 card. Motherboards with PCI slots are becoming increasingly difficult to source. Customers should, therefore, consider using the ATS9146 PCIe waveform digitizer, which provides 14-bit, 125 MS/s dual-channel sampling, and dual-port memory, for a lower price than ATS460. Page 1

125 MS/s 14-Bit PCI Digitizer Analog Input An ATS460 features two analog input channels with extensive functionality. Each channel has 65 MHz of full power analog input bandwidth. With software-selectable attenuation, you can achieve an input voltage range of ±20 mV to ±10 V. Attenuating probes (sold separately) can extend the voltage range even higher. Software-selectable AC or DC coupling further increases the signal measurement capability. Softwareselectable 50 Ω input impedance makes it easy to interface to high-speed RF signals. For applications that require the best signal integrity,...

125 MS/s 14-Bit PCI Digitizer A BUFFER_OVERFLOW flag is asserted if more than 512 buffers have been acquired by the acquisition system, but not transferred to host PC memory by the AutoDMA engine. While Traditional AutoDMA can acquire data to PC host memory at sustained rates in excess of 100 MB/s, an overflow can occur if more than 512 triggers occur in very rapid succession, even if all the on-board memory has not been used up. Many ultrasonic scanning and medical imaging applications do not need any pre-trigger data: only post-trigger data is sufficient. NPT AutoDMA is designed...

125 MS/s 14-Bit PCI Digitizer AsyncDMA uses overlapped IO to re-start DMAs and consume data, thereby minimizing CPU usage to almost 0%, reducing re-arm time of DMAs and allowing the full bus bandwidth to be realized. A programmable trigger delay can also be set by the user. This is very useful for capturing the signal of interest in a pulse-echo application, such as ultrasound, radar, lidar etc. Another advantage of AsyncDMA is that it can provide the full bus bandwidth to a multi-card Leader/ Follower system. Trigger Time Stamp Some helper routines are provided for programming languages...

125 MS/s 14-Bit PCI Digitizer Optional External Clock ATS460 External Clock option provides an SMA input for an external clock signal, which should be a high slew rate signal or LVTTL signal. RoHS Compliance While the ATS460 features low-jitter, high-reliability 125 MHz and 100 MHz oscillators as sources of the timebase system, there are occasions when ATS460 has to be synchronized to an external clock source. User can set the input impedance and coupling for the external clock input by setting the appropriate DIP switches located in the top-left corner of the ATS460 V1.2 printed circuit...

125 MS/s 14-Bit PCI Digitizer operating systems. Current software and driver releases may work with these operating systems but they are not officially supported. Due to lack of demand and due to the fact that Microsoft no longer supports these operating systems, AlazarTech no longer supports Windows 8, Windows 7, Windows XP, Windows Vista, Windows Server 2012, Windows Server 2008 R2, and Windows Server 2008. Linux Support AlazarTech offers Dynamic Kernel Module Support (DKMS) drivers for the following Linux distributions: Ubuntu, Debian, and RHEL®. AlazarTech DKMS drivers may work for...

125 MS/s 14-Bit PCI Digitizer Dynamic Parameters Trigger Delay Typical values measured using a randomly selected ATS460 with Amplifier Bypass Mode. Input was provided by a HP8656A signal generator, followed by a 9-pole, 1 MHz band-pass filter (TTE Q36T-1M-100K-50-720B). Input frequency was set at 1 MHz and output amplitude was 500 mV rms, which is approximately 95% of the 525 mV rms full scale input in Amplifier Bypass Mode.
