The New 16-channel DAP 5400a1626.
The new 16-channel DAP 5400a1626 has eight onboard
A/D converters that each can acquire 1250k 14-bit resolution
samples per second simultaneously, for an aggregate
throughput of 10M samples per second. The board has
128MB of onboard memory for data buffers, and uses DMA
bus-mastering to transfer data to the PC.
A DAP 5400a board samples its sixteen inputs in two groups of eight.
Applications that require more than eight simultaneously sampled
channels can take advantage of the synchronization feature common
to all DAP boards. If an application requires sixteen simultaneous
inputs, each acquiring data at 1250k samples per second, then
two synchronised DAP 5400a boards, installed in a single PC,
can deliver the aggregate throughput of 20M samples per second
shared by these sixteen simultaneous inputs. A system that contains
five synchronized DAP 5400a boards provides 40 simultaneous
channels, a throughput of 50M samples per second, and onboard
memory of 640MB.
The new DAP 5400a model runs DAPL 2000: the multitasking
real-time operating system for PC-based data acquisition and control,
the onboard intelligence that comes with every DAP. A user normally
controls DAPL through Windows (XP, 2000, NT, ME, 95, 98) -- either
locally or over a network -- using DAPcell client software and a
Windows application like LabVIEW or Visual Basic. Every standard
DAP model in current production also will run under LiNUX. DAPL
itself runs on the onboard processor that every DAP uses to perform
data acquisition and control tasks in real time, free from any delays
imposed by the operating system or by other software running on
the local server hardware.
