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 PXI-5671 features an onboard ultrahigh-stability oven- capabilities of the PXI-5671. Also included are a number of interactive,  
controlled crystal oscillator (OCXO), which provides frequency instructional examples and interactive online help that can help jump-  
stability of 20 ppb and frequency accuracy of 50 ppb. These start 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.

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.
