PI-41000 Digital Acquisition Card

Products > Data Acquisition > PI-41000  


  • Acquire Data @ 320 MB/sec
  • 256 or 512 MB DRAM Buffer 
  • 80 MB/sec DMA Transfer  
  • Two 16-bit Input Channels or, One 32-bit Channel


  • Testing Imaging Devices
  • Synchronous Data Capture


The PI-41000 is a CompactPCI® bus based instrument card that allows the user to capture up to 32-bits of digital data into an on-board memory at clock rates up to 80 MHz. The inputs are software configurable to provide one 32-bit wide channel, one 16-bit wide channel with double depth or two 16-bit channels.

Each digital data channel requires three timing signals, frame, line and pixel to accommodate the data capture.  When operating in a two channel mode, clocks from channel A can be used to provide timing to channel B.  For wider words or multiple channels, more boards can be used in parallel.  

Memory Storage:

The PI-41000 Digital Acquisition Board has on-board memory of 256 MB or 512 MB.  When the instrument is configured to operate as a single 16-bit channel the two input buffers are combined to maximize the memory depth.  In this mode and with a 256 MB memory the unit will store 128 Mwords.  When the same instrument is configured for one 32-bit channel or two independent 16-bit channels, the unit will store 64 Mwords. 

Data Acquisition and Inputs:

The PI-41000 was designed primary for image capture.  To synchronize data, the board requires frame, line and pixel timing signals.  Each of these timing signals has an associated counter.  The line and pixel counters when combined provide an important Area of Interest (AOI) feature.  This feature provides the ability to capture a sub-image of a defined area on the imaging device. The Area of Interest acquisition provides for an efficient use of the capture memory. Data can be collected on a defined pixel area of the imager without acquiring and storing the complete image.  By using the AOI feature the user can process and display and area of any size up to 64K x 64K pixels.

The input levels for both data and clocks are 3.3V CMOS or LVDS.  The inputs for data and timing signals are terminated with approximately 1 KOhm.  To minimize reflections the drive for the data and timing signals should be a back-matched with 50 ohms.  As an option the input impedance of data and/or timing signals can be changed to 50 ohms.  The data input is via two 40 pin header connectors.  The timing signal connectors are SMA. 

The PI-41000 can be used by itself in a CompactPCI-based test system, or as the digital acquisition component of the PI-3105 Multi-Channel Data Acquisition System or of a fully-integrated, turnkey imager test system.

Data Transfer and Software:

The PI-41000 is capable of becoming a bus master and therefore uses DMA to transfer the captured data to from the on-board memory to the Host CPU. 

The PI-41000 is supported by Pulse Instruments’ PI-DATS and PI-Controller software. DLLs, documentation, and sample code are also available to facilitate integration into custom applications written in C++, VisualBasic, VBA, LabVEW, HTBasic, IDL, or MATLAB.
