Overview
The National Instruments PXI-5671 is a 2.7 GHz RF vector signal
generator module with quadrature digital upconversion. Digital
upconversion provides a more efficient means of waveform
generation resulting in a tremendous reduction in download and
signal generation time. The NI PXI-5671 provides 16-bit resolution
arbitrary waveform generation at 100 MS/s (400 MS/s interpolated),
up to 512 MB of memory, and 20 MHz real-time bandwidth. The
PXI-5671 can generate custom and standard modulation formats
such as AM, FM, PM, ASK, FSK, MSK, GMSK, PSK, QPSK, PAM,
and QAM.
The Modulation Toolkit for LabVIEW accompanies the PXI-5671,
providing functions and tools for signal generation, analysis,
visualization, and processing of custom and standard digital and
analog modulation formats.
The combined functionality of the PXI-5671 and the Modulation
Toolkit deliver a highly flexible and powerful solution for scientific
research, consumer electronics, communications, aerospace/defense,
and semiconductor test applications as well as for emerging areas
including software-defined radio, radio-frequency identification
(RFID), and wireless sensor networks.

specifications make it useful for a range of automation applications.
A sophisticated calibration scheme is implemented in the PXI-5671
to ensure power level accuracy over varying temperatures from
0 to 55 °C. This feature is important to many applications, especially
in manufacturing environments where the stable operation over
varying temperature ranges is critical.
Software
Hardware
The PXI-5671 provides vector signal generation from 250 kHz to
2.7 GHz over a wide range of signal levels from -145 dBm to +10 dBm
in a compact, 3 slot 3U module. It follows industry-standard plug and
play specifications for the PXI bus and can be seamlessly integrated
with compliant systems.
The PXI-5671 features an onboard ultrahigh-stability ovencontrolled crystal oscillator (OCXO), which provides frequency
stability of ±20 ppb and frequency accuracy of ±50 ppb. These
The PXI-5671 is shipped with the NI-RFSG instrument driver and the
Modulation Toolkit for LabVIEW. NI-RFSG is a fully functional
instrument driver, compatible with a variety of application software
environments such as NI LabVIEW, LabWindows/CVI, and C.
NI-RFSG features easy-to-use functions for configuring the timing
and synchronization, CW tone, and arbitrary waveform generation
capabilities of the PXI-5671. Also included are a number of interactive,
instructional examples and interactive online help that can help jumpstart your application test development.
2.7 GHz RF Vector Signal Generator
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-5671. 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.

Superior Flexibility
Providing customers with a flexible platform is necessary to meet the
needs of today’s complex, rapidly evolving systems. The PXI-5671
consists of two components – the NI PXI-5610 2.7 GHz RF
upconverter and the NI PXI-5441 arbitrary waveform generator, a
high-spectral-purity baseband signal generator with onboard signal
processing. The PXI-5610 and the PXI-5441 work together to
provide vector signal generation from 250 kHz to 2.7 GHz. Because
of the flexible hardware and software, and with access to low-level
driver functionality, the PXI-5610 and the PXI-5441 can also be used
independently for RF upconversion and arbitrary waveform
sequencing. For advanced applications, combine additional modular
instruments in the same PXI chassis with the PXI-5671 and take
advantage of the tight synchronization between PXI modules. For
example, combine the PXI-5660 RF Vector Signal Analyzer with the
PXI-5671 to build an RF communications test system with complete
modulation and demodulation capabilities.
Calibration
The PXI-5610 and the PXI-5441 are calibrated separately by
National Instruments with NIST-traceable and ISO-9002-certified
calibration certificates. Temperature variations are calibrated and
corrected during normal operation resulting in very high stability
and repeatability.
