S Series Multifunction DAQ
16-Bit, 250 kS/s/Channel, 8 Analog Inputs
Data Compaction
With the release of NI-DAQmx 7.4 or later, data compaction
is available for stream-to-disk applications. The NI-DAQmx
compaction feature strips unused or unwanted bits of data from
each sample taken from your S Series device before it is permanently
recorded to hard disk. This is helpful because hard drives are
typically the throughput bottleneck compared to the PCI/PXI bus
and PC RAM memory read/write speed. Using data compression,
users with standard hard drives can see up to 20 percent higher
throughput when streaming-to-disk.
Cleaner Code Development –
Basic and advanced software
functions have been combined into one easy-to-use yet powerful
set to help you build cleaner code and move from basic to advanced
applications without replacing functions.
High-Performance Driver Engine –
NI-DAQ delivers maximum I/O
system throughput with a multithreaded driver.
Test Panels –
With the Measurement & Automation Explorer
configuration utility, you can test all of your device functionality
before you begin development.
Scaled Channels –
Easily scale your voltage data into the proper
engineering units using the NI-DAQ Measurement Ready virtual
channels by choosing from a list of common sensors and signals or
creating your own custom scale.
Data-Logging Software –
VI Logger Lite is configuration-based
software designed specifically for data logging. Features include
easy logging and viewing of data, data extraction to Microsoft
Excel, and code generation in LabVIEW.
LabVIEW Integration –
All NI-DAQ functions create the waveform
data type, which carries acquired data and timing information
directly into more than 400 LabVIEW built-in analysis routines for
display of results in engineering units on a graph.
Signal Conditioning
With the release of NI-DAQmx 7.4 or later, all S Series devices are
compatible with parallel-mode SCXI modules.

Table 2. Most Popular Parallel-Mode SCXI Modules
SCXI is limited to 100 kS/s for 16-bit accuracy and 333 kS/s for
12-bit accuracy when used in multiplexed mode. However, in
parallel mode, the sample rate is limited by the maximum scan rate
of the data acquisition device. When SCXI is used in parallel mode
with S Series, all channels are simultaneously sampled and the
sample rate is limited by the S Series device, from 250 kS/s per
channel to 10 MS/s per channel.
Measurement Services Software
National Instruments measurement services software, built
around NI-DAQmx driver software, includes intuitive application
programming interfaces, configuration tools, I/O assistants, and
other tools designed to reduce system setup, configuration, and
development time. This software is included with your data
acquisition purchase. Helpful features include:
Automatic Code Generation –
DAQ Assistant is an interactive
guide that helps you navigate through configuring, testing,
and programming measurement tasks and generates the
necessary code automatically for LabVIEW, LabWindows/CVI, or
Measurement Studio.
NI-DAQmx Base Driver
NI-DAQmx Base (available at
ni.com/downloads)
offers Mac OS X
and Linux users a programming interface similar to NI-DAQmx. It
includes ready-to-use LabVIEW VIs and C function features similar
to those included in NI-DAQmx driver software.
