Overview and Applications
National Instruments S Series devices combine the latest in PC
technologies to deliver simultaneous-sampling, high-bandwidth
capabilities for low and high-channel-count data acquisition and control
systems. Use S Series devices in a variety of applications including:
• Stimulus/response applications where synchronization among high-
speed analog input (AI), analog output (AO), and digital I/O is required
• 42 V automotive applications
• Radar, sonar, ultrasound
• Transient/ballistics measurements
• High-energy physics
• IF digitization
Features
The NI high-performance S Series DAQ devices have the same
basic features of a typical multifunction device – eight digital I/O lines,
two counter/timers, two analog outputs, RTSI or PXI trigger bus for
multidevice synchronization, and PFI lines for software-controlled routing
of timing and triggering signals. S Series devices exceed the analog input
performance of traditional multiplexed devices with features including:

Table 2. Special Features
S Series Multifunction DAQ 12 or 16-Bit,
1 to 10 MS/s, 4 Analog Inputs
Dedicated A/D Converters per Channel
– help you achieve faster
sampling rates per channel, simultaneous sampling, and better
dynamic accuracy for transient or frequency measurements.
200 mV to 42 V Input Ranges
– configure each analog input channel
to read from a very wide variety of voltage ranges. The input
impedance is lower for 20 and 42 V ranges, preserving the bandwidth
for signals with high frequencies and large amplitudes.
AC or DC Coupling
– configure analog inputs for AC or DC coupling
on a per-channel basis. AC coupling removes the DC offset for
applications only analyzing signals in the frequency domain.
Antialias Filters (NI 6115 and NI 6120)
– the antialias filters are turned
on from software on a per-channel basis. NI 6115 devices have 50 or
500 kHz filters for each channel, and NI 6120 devices have 100 kHz
filters for each channel.
Large Onboard Memory (NI 6115 and NI 6120)
– NI 6120 devices
feature a 64 MS onboard memory, and NI 6115 devices feature a
64 or 32 MS onboard memory. With the extra memory, which
requires no extra programming, you can capture high-bandwidth
signals over long periods of time, even if multiple devices are sharing
the same PCI or PXI bus.
Hardware-Timed Digital I/O
– the digital I/O lines can synchronize
with the analog input, analog output, counter/timer I/O, or an
external clock for mixed-signal measurement applications. Using the
onboard FIFO, you can achieve reliable data transfers to 10 MB/s.
Phase Locking (PXI only)
– synchronize multiple devices to a
common PXI backplane clock to preserve the phase between
measurements across multiple device analog input channels.

S Series Multifunction DAQ 12 or 16-Bit,
1 to 10 MS/s, 4 Analog Inputs
NI Spectral Measurements Toolkit
This toolkit includes all of the analysis and presentation tools to
convert your S Series device into a full-featured spectrum analyzer.
The toolkit includes:
• Measurements such as in-band power and adjacent-channel power
• 3D spectrogram
• Analog modulation and demodulation
• I-Q data for digital demodulation
• Highly optimized FFT processing
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
sampling 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.
Automatic Code Generation
– DAQ Assistant is an interactive guide
that helps you navigate through configuring, testing, and programming
measurement tasks and automatically generates the necessary code
for LabVIEW, LabWindows/CVI, or Measurement Studio.
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-DAQmx 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 module functionality
before you begin development.
Scaled Channels
– Easily scale your voltage data into the proper
engineering units using the NI-DAQmx 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-DAQmx 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.
High-Performance Data Throughput
Using NI-DAQmx driver software and S Series, you can take full
advantage of your PC’s throughput potential, which is useful in
many applications including transient recording.
Flexible Data Transfer
With NI-DAQmx, you can choose where to accumulate data – on the
onboard memory, PC RAM memory, or PC hard drive memory.
Thus, you can balance your PC application requirements and
stream-to-disk/memory capabilities. In any case, NI-DAQmx
optimizes data transfers by using DMA (direct memory access) and
transferring large chunks of data, while ensuring no data loss. You
can also choose the format of your data, further optimizing
throughput. Choices include raw (binary), scaled, or the high-level
waveform data type. Using these techniques, you can achieve rates of
more than 40 MS/s sustained over the PCI/PXI bus to hard drive
(depending on the PC).
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.
Signal Conditioning
With the release of NI-DAQmx 7.4 or later, all S Series devices are
compatible with parallel-mode SCXI modules.
