MODEL AD8-1250DMA
Model AD8-1250DMA contains a
1.25 gigasample/second 8 bit A/D, 8 GB of on-board SDRAM memory and the
ability to transfer data directly into the computer system's memory at
up to 320 MB/s on 64-bit PCI systems. Sampling is controlled by an external
clock input, which may be in the frequency range between 20 MHz and 1250
MHz. Multiple boards may be configured to acquire either concurrently,
for more simultaneous acquisition channels, or sequentially, with an automatic
overlap selectable from 0 to nearly 2GB, in 512KB steps, for longer record
length.

MODEL DA8-1250DMA-16GB & MODEL DA8-1250DMA-8GB
Model DA8-1250DMA-16GB and
-8GB contain a 1.25 gigasample/second 8 bit D/A converter, 16 GB or
8 GB, respectively, of on-board SDRAM memory and the ability to transfer
data directly from the computer system's memory at up to 320 MB/s on
64-bit PCI systems. Sampling on D/A operation may only be controlled
by an external clock input between 1000 MHz and 1250MHz. Multiple boards
may be configured to output analog streams concurrently, for more simultaneous
analog output channels. The board's RAMs are first filled with data
by the host computer and then, in response to an external trigger, the
two boards begin outputting data via their D/A converters. When two
or more DA8-1250DMA boards are run concurrently, up to an 8 sample skew
may exist between boards (this skew is not present on AD8-1500DMA A/D
models, just on DA8-1250DMA models).
