The CPCI-510 Family consists of several advanced-
performance, data acquisition boards based on the 3U 32-bit
CompactPCI Form Factor. CompactPCI is quickly becoming
the preferred bus architecture choice for new embedded or
ruggedized applications. CompactPCI combines desktop PCI
performance and PC software compatibility with a rugged
Eurocard packaging and passive backplane architecture.
With an emphasis on continuous, non-stop, high-speed
streaming of A/D samples to host memory or disk, the system
has been optimized for a wide range of signal-processing and
data-recording applications. The CPCI-510 can collect huge
amounts of "seamless" digitized data to host memory.
Incorporating a unique "banked" FIFO architecture, the
CPCI-510 moves two A/D words in each 32-bit PCI transfer.
The FIFO memory (8 Ksamples deep) serves to decouple the
precise timing of the A/D converter from the block bursts of
the PCI bus.
The CPCI-510's modular analog front ends utilize DATEL's
low-noise, wide-bandwidth sampling A/D converters. All
models exhibit excellent harmonic distortion and perform well
in DSP/FFT applications. Software for Windows 95/98, NT,
and LabVIEW
implements a menu-driven, no-programming",
fast data recording and display system to memory or disk.

Several different "pluggable" analog options offer up to 16
input channels in single-ended or differential configurations,
multiple input ranges, sampling rates to 10 MHz per channel,
12-, 14-, 16-bit A/D resolutions, and various simultaneous
sampling configurations (A/D per channel) up to 16 channels.
A/D-per-channel boards may be operated in "software
differential" mode. Two A/D's are applied to the high and low
legs of a single differential input signal. The two data values
are then algebraically subtracted, either on the fly in real time
or after all samples have been stored. Channel capacity in
"software differential" is one-half the number of single-ended
channels.
Two on-board software-programmable timebases run the A/D
sample clock. A 40 MHz frequency synthesizer provides high
resolution, whereas the 10 MHz 16-stage programmable
divider offers very low clock jitter. If preferred, external clocks
can be used for both the A/D start clock and the trigger. And
several CPCI-510's can be run in parallel via external clock for
many simultaneous channels. A programmable 24-bit sample
counter collects long blocks up to 16 million samples. The
trigger system collects a single fixed length frame, N repeating
frames separated by programmable delays, or it can run
"forever". Interrupts to the PCI bus are programmable from
the FIFO half full flag, the bus master block transfer done, or
the sample counter.

System features optimize gapless sampling without data loss.
A pretrigger system can collect data continuously to host
circular memory (ring buffer) of several megabytes or more.
When an external trigger is received, the CPCI-510 will count
down the number of preloaded post-trigger samples then
automatically stop when all samples are collected. The trigger
sample may then be found using a negative circular offset into
the ring buffer, knowing the post-trigger sample count.
In addition, a digital marker input will tag data samples on the
fly as often as needed. This provides later identification of
external events without stopping sample collection. A 16 bit
D/A converter is included to set the trip level to generate
external analog triggers. Or the D/A can be used for analog
output. Plus 16 digital inputs and 16 digital outputs are
available.
Like any PC hardware, the CPCI-510 needs software to
command and control it. Data acquisition, data display and
data storage applications are available for Windows
95/98,
Windows
NT, and National Instrument's LabVIEW
. Simply
install the software on your CompactPCI system and you will
be acquiring and storing data within minutes. When data
acquisition is complete, any third party data processing
application can be used to analyze the results. Programmers
developing their own code will appreciate the commented
source code available for all of DATEL's software. The software
was designed using common integrated development
environments such as Visual C/C
++
.

FOOTNOTES
1.
CPCI-510J and 510L bipolar input is user-selectable 5V
or 10V (default) per channel. Total gain error over
temperature range is 4 LSB maximum. Total zero/offset
error over temperature range is 4 LSB maximum.
Monotonicity: no missing codes over temperature range.
2.
The CPCI-16M analog module accepts an optional
surface mount precision resistor on each channel for
limited gain increase. Preliminary specifications are
shown. CMR = 90dB at DC, gain = 1. Input bias current
= 20 pA.
3.
Data output of the CPCI-14P and Q analog module is
pipelined with a 4-sample delay after the first sample
clock. The design is intended for semi-continuous
sampling of wideband signals and is less suitable for low
speed data acquisition.
4.
Preliminary specifications are shown for the CPCI-510P
and CPCI-510Q. Contact DATEL for availablility.
5.
Please note that the D/A section is not a streaming
design.
