Overview
The National Instruments NI PXI-5441 is a 100 MS/s arbitrary
waveform generator with Onboard Signal Processing (OSP). OSP
functions include FIR and CIC interpolation filters, digital per-filter
gain and offset control, a numerically controlled oscillator (NCO)
and IQ mixing for quadrature digital upconversion. With 16-bit
resolution and -91 dBc close-in spurious free dynamic range (SFDR),
the PXI-5441 brings instrument quality specifications to applications
requiring digital upconversion and baseband interpolation such as
prototyping, validating, and testing communications, radar, and
electronic warfare systems. Since the PXI-5441 is a full-featured
arbitrary waveform generator, it is also capable of generating general
purpose electrical test signals and has a maximum output range of
12 Vpk-pk into a 50 load.
Ω
By using the PCI bus to communicate with the host computer, the
PXI-5441 can download waveforms at up to 100 MB/s, far faster than
traditional GPIB-based instruments. Using the Synchronization
and Memory Core (SMC) architecture of the PXI-5441, you can
create mixed signal test systems by synchronizing the generator
with digitizers and digital waveform generator/analyzers or
synchronize multiple generators to form a phase-coherent
multi-channel generator for generating I/Q signals for applications
such as MIMO (multiple-input multiple-output) or beam-forming
antenna schemes.
Onboard Signal Processing
Onboard signal processing (OSP) (Figure 1) significantly extends
waveform playback time and reduces the time required to compute
and download waveform data by computing the waveform data
using the PXI-5441’s field programmable gate array (FPGA). OSP
delivers several signal processing functions used to modify the data
stored in waveform memory during generation. The signal
processing functions are:
Independent I and Q pre-filter gain and offset
For adding gain and offset imbalance impairments, I and Q pre-filter
gain and offset can be adjusted before or during the generation of an
output signal.
Finite impulse response (FIR) filter
The FIR filter shapes the waveform data, compensates for the
cascaded-integrator comb (CIC) filter response, and interpolates the
waveform data by 2, 4, or 8x. The FIR filter coefficients are
programmable and include flat, raised cosine, root raised cosine,
Gaussian, or custom. For implementing custom filters, consider the
NI Digital Filter Design Toolkit which includes several advanced
filter design tools for designing, analyzing, and simulating floatingpoint and fixed-point filters.
Cascaded-integrator comb (CIC) filter
For upsampling waveform data to a high sample rate, the CIC filter
efficiently interpolates by 6x to 256x.
Numerically controlled oscillator (NCO)
The NCO produces sine and cosine waveform data for quadrature
digital upconversion and features 355 nHz frequency resolution and
0.0055o phase resolution for precise control of impairments such as
frequency error and quadrature skew. NCO frequency and phase can
also be adjusted before or during waveform generation.
100 MS/s, 16-bit Arbitrary Waveform
Generator with Onboard Signal Processing
Figure 1. Onboard Signal Processing uses the PXI-5441’s FPGA to perform in-line
processing of the waveform data stored in the module’s memory.
In addition to being an arbitrary waveform generator with
waveform sequencing capability, the PXI-5441 uses the OSP
functions to perform:
Quadrature digital upconversion with impairments
In quadrature upconversion, I and Q complex waveform data is
stored in waveform memory and is passed to the OSP block. OSP
then shapes and interpolates the data using the FIR filters,
interpolates it up to a high sample rate using the CIC filters, and then
upconverts the data to a programmable carrier frequency up to
43 MHz. You can choose to suppress the lower or upper modulation
sideband by adjusting the NCO in-phase and quadrature output
phase settings.
For modeling channel effects and testing the robustness of a receiver,
the OSP can add several impairments to the signal on the fly (during
waveform generation). IQ Gain Imbalance and DC offset
impairments are added by adjusting the per-filter gain and offset
settings, while quadrature skew and frequency error can be
introduced by adjusting the I or Q carrier phase and frequency.

Baseband interpolation
Useful for generating smooth baseband signals, such as I and Q
signals, you can use the PXI-5441’s OSP block to interpolate low
sample rate waveforms to a much higher sample rate, thereby
improving the output frequency spectrum by relocating zero-order
sample-and-hold reconstruction images to higher frequencies. With
the images at higher frequencies, the PXI-5441’s 7th order low-pass
analog filter can greatly suppress them without disturbing the
signals’ amplitude response or phase information. For example,
a waveform created at 10 kS/s sample rate could be interpolated to
10.24 MS/s by using 4x FIR interpolation and 256x CIC
interpolation. The upsampled signal is then passed to the DAC which
can also interpolate by 2, 4, or 8x resulting in an effective sampling
rate of 81.92 MS/s (8x DAC interpolation). Since the original
waveform was sampled at only 10 kS/s, rather than 81.92 MS/s, a
1:8,192 compression ratio is achieved, resulting in dramatically faster
waveform computation and download times. Alternatively, the
resulting compression can be used to efficiently store data in the
PXI-5441’s onboard memory allowing for much longer playback
times without streaming from arrays of high-speed disk drives. Long
playback times are essential for improving the statistical significance
of many communications measurements and displays such as bit
error rate, trellis plots, and constellation plots.

Using the OSP block’s NCO, the PXI-5441 can generate sine, square,
triangle, ramp and other standard and user-defined waveforms just
as function generator does. The frequency of the output waveform
may be adjusted during generation with 355 nHz resolution for
generating phase continuous frequency sweeps and hops. The phase
is also adjustable relative to other synchronized instruments, the
PXI 10 MHz reference clock or an externally supplied reference clock.

Generator with Onboard Signal Processing
DAC Interpolation
The NI 5441 uses digital interpolation to improve the output signal
quality of smooth waveforms. Every digital-to-analog converter
(DAC) produces reconstruction images in the frequency domain as
a result of the conversion process. Appearing at |fo ± nfs|, where fo is
the frequency of the desired signal and fs is the sampling rate,
reconstruction images are undesirable for smooth signals, such as
sine waves.
Typically, arbitrary waveform generators suppress the
reconstruction images by using high-order low-pass filters with
a cutoff frequency near the generator’s Nyquist frequency (50 MHz
for a 100 MS/s sample rate). By using a high-order filter with such
a low cutoff frequency, the filter’s non-idealities, such as passband
ripple and non-linear phase significantly affect the generator’s
performance. The NI 5441 uses digital interpolation to increase
the effective sample rate, relocating the reconstruction images to
higher frequencies.
duration is unknown before generation, a hardware or software
trigger can advance the generator to the next waveform in the
sequence. The NI 5441 implements advanced triggering behavior
with four trigger modes: single, continuous, burst, and stepped. For
a detailed discuss of these modes, please consult the NI Signal
Generators Help Guide available at ni.com/manuals.

Memory
Figure 4. NI’s SMC-based arbitrary waveform generators increase test throughput by
storing all the waveforms and sequences required for a set of test in onboard memory.
NI’s SMC-based generators have the unique capability to store
multiple sequences and their associated waveforms in the generator’s
onboard memory (Figure 4). In automated test situations involving
multiple tests each requiring a different waveform sequence, all of the
sequences and waveforms can be downloaded once at the beginning
of the test cycle and held in the generator’s memory for the entire
session. By downloading all required waveforms and sequences once,
instead of repeatedly reloading them for each test, the SMC-based
generators save test time and improve test throughput.
Timing and Synchronization
Figure 3. Using a combination of digital interpolation and analog filtering, the NI 5441
greatly reduces the DAC reconstruction images as shown for the 10 MHz sine signal
generated at 100 MS/s using 4x interpolation for a 400 MS/s effective sampling rate.
(Noise floor is limited by the measurement device.)
By doing so, the required analog filter cutoff frequency is increased
which lessens the filter’s distortion effects. The combination of
digital interpolation and analog filtering enable the NI 5441 to have
excellent passband flatness and improved image rejection ensuring a
low-distortion output signal.
Using T-Clock synchronization technology, multiple NI 5441’s can
be synchronized for applications requiring a greater number of
channels, such as I/Q signal generation or multiple IF generation for
MIMO systems. Since it is built into the SMC, T-Clock can
synchronize the NI 5441 with SMC-based high-speed digitizers and
digital waveform generator/analyzers for tight correlation of analog
and digital stimulus and response. Using onboard calibration
measurements and compensation, T-Clock can automatically
synchronize any combination of SMC-based modules with less
than 500 psrms module-to-module skew. Greatly improved from
traditional synchronization methods, the skew between modules
does not increase as the number of modules increases. To achieve
even better performance, a high-bandwidth oscilloscope can be used
to precisely measure the module-to-module skew. Using the
oscilloscope measurement for calibration information, T-Clock can
achieve < 20 psrms module-to-module skew (Figure 5).
For sharp waveforms, such as square waves, pulses, and video signals,
interpolation and analog filtering can be disabled resulting in fast
rise/fall times and low pulse aberration (overshoot, undershoot, etc).
Waveform Sequencing and Triggering
The NI 5441 can be programmed to sequence and loop a set of
waveforms. Several methods can be used to advance through the
sequence of waveforms. In some cases, the duration of each
waveform is known in advance, so the generator can be programmed
to loop each waveform a specified number of times. When the
Figure 5. Using the Synchronization and Memory Core’s T-Clock synchronization,
multiple NI 5441 can achieve less than 20 ps channel-to-channel skew.

The NI 5441’s sample clock has three modes: Divide-by-N, HighResolution, and External. The direct digital synthesis (DDS) based
high-resolution sample clock has a sample rate resolution of
1.06 µHz. This offers you exceptional stability and sampling rate
flexibility. The NI 5441 can also import its sample clock from the
CLK IN, PXI star trigger and PXI trigger bus. In addition, you can
phase lock the NI 5441’s oscillator to an external reference or the
PXI 10 MHz reference clock.
Driver Software
Accurate, high-throughput hardware improves the performance of
a measurement system, but easy-to-use, reliable software reduces
your development time and ongoing support costs. NI-FGEN, the
driver software for the NI 5441, is the world’s most advanced and
thoroughly tested arbitrary waveform generator software
and features:
• Intuitive application programming interface (API) – In LabVIEW,
LabWindows/CVI, VisualBasic and Visual C/C++, NI-FGEN’s API
is engineered to use the least number of function’s possible while
also maintaining flexibility. Each driver function has thorough
online searchable documentation. The NI-FGEN Quick Reference
Guide further simplifies programming by providing an overview
of each driver function’s LabVIEW icon, function name,
parameters, and data types.
• LabVIEW Express VIs – For generating an arbitrary repetitive
signal, the LabVIEW Express VI is a configuration driven way
to program the NI 5441 without accessing the underlying
NI-FGEN functions.
• Function generator mode – Using the OSP’s numerically
controlled oscillator, the PXI-5441 can behave as an arbitrary
function generator with 355 nHz frequency resolution. Using
function generator mode, you can generate phase continuous
frequency sweeps and hops.
• Soft front panel – For quick non-programmatic use of the
NI 5441, the soft front panel supports arbitrary waveform and
standard waveform generation.
• Example programs – NI-FGEN provides 23 programming
examples for LabVIEW, LabWindows/CVI, VisualC++ 6.0 and
.Net, and VisualBasic 6.0 so you don’t have to start from scratch.
• LabVIEW Real-Time Support – For remotely deployed
autonomous measurement systems or applications requiring the
highest possible reliability, NI-FGEN supports LabVIEW’s
Real-Time module.

Modulation Toolkit for LabVIEW1
The Modulation Toolkit for LabVIEW provides functions for
signal generation, analysis, and visualization of custom and
standard analog and digital modulation. With the Modulation
Toolkit, you can also develop and analyze custom modulation
formats and generate these with the PXI-5441. Some of the
standard measurement functions include EVM (error vector
magnitude), MER (modulation error ratio), and ρ (rho). Functions
are also available for injecting impairments including
IQ Gain Imbalance, Quadrature Skew, and AWGN (additive white
Gaussian noise). Visualization functions include trellis,
constellation, and 2D- and 3D-eye diagrams. This hardware and
software combination gives you access to customizable functionality
not available in traditional instrumentation.

Analog Waveform Editor1
The NI Analog Waveform Editor is an interactive software tool for
creating and editing analog waveforms. In the editor, each waveform
is comprised of different segments, where each segment is comprised
of a collection of “primitives”. You can create a new waveform
segment by selecting from a library of over 20 waveform “primitives”
(Table 1), by entering a mathematical expression, or importing data
from a file. Waveform primitives can then be combined point-bypoint using addition, multiplication, or division to create more
complex segments (Figure 6).
