The Pulse Instruments PI-4005
Data Acquisition System is designed specifically for the low noise acquisition of data from
imaging devices like CMOS Imagers, CCDs, and IR Focal Plane Arrays.
The system consists of a set of low noise mainframes, the host computer, and
software to setup and control acquisition of data from the device under test
Preamplifier modules are available for applications that
require close proximity of a preamplifier to the device under test.
A host of programmable features make the system ideal for
Research and Development, Characterization and Product Test.
The system is designed to operate as part of
an integrated Test System, or to function as a stand alone data
Taking advantage of the VME bus, the PI-4005 Acquisition
System can acquire analog data at rates up to 40 MHz with 10 bit resolution or with up to
16 bit resolution at 2 MHz. Digital acquisition cards are also
The system is designed to control and
synchronize multiple acquisition cards. A single mainframe can house
up to eight acquisition cards and multiple mainframe configurations
Separate power supplies and Separate ground systems are used
for the Analog and Digital circuitry, with only the required ground connection underneath
the A/D converter as the common point. This common point on the digital side of the card
is supported by a separate 5V power supply. This is part of the PI-4008 analog power
mainframe, and separates the A/D converter from the power supplies that are on the bus.
Each Data Acquisition Card is
complete with two stages of Amplification, Filtering, Correlated Double Sampling, A/D
Converter, and 16 Megabytes of RAM per channel.
An Area of Interest (AOI) feature is included for sub-image acquisition. This
feature allows processing and display of a window of the focal plane of any size up to
2048 x 2048 pixels. Area of Interest acquisition provides efficient use of memory.
Operations can be computed on selected pixel areas without having to acquire the entire
image to save on board memory.
