can perform continuous streaming from disk at the maximum output
rate of the instrument, 25 MS/s (100 MB/s). For extended waveform
generation, the NI PXIe-5672 is capable of streaming continuous
waveforms from disk for more than five hours. Applications that benefit
from this capability include broadcast video test, record and playback,
and extended bit error rate (BER) testing.
The National Instruments PXIe-5672 is a 2.7 GHz RF vector signal
generator with quadrature digital upconversion. Digital upconversion
provides an efficient mechanism of waveform generation resulting in
significant waveform download times. The NI PXIe-5672 provides
16-bit resolution arbitrary waveform generation at 100 MS/s (400 MS/s
interpolated), up to 512 MB of memory, and up to 20 MHz of instantaneous
signal bandwidth. The NI PXIe-5672 is a general-purpose vector signal
generator that can generate standard modulation formats such as AM,
FM, PM, ASK, FSK, MSK, GMSK, PSK, QPSK, PAM, and QAM. One
accompanying tool is the NI Modulation Toolkit for LabVIEW, which
provides functions for signal generation, analysis, visualization, and
processing of custom and standard digital and analog modulation
formats. The combined functionality of the NI PXIe-5672 and the
Modulation Toolkit delivers 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. For specific
communications standards, you can use various software add-ons to
generate modulated signals according to standards such as WCDMA,
DVB-H, and ZigBee.
Quadrature Digital Upconversion
The NI PXIe-5672 uses a superheterodyne upconversion approach to
minimize quadrature error. Digital upconversion of baseband I/Q
waveforms to an intermediate frequency (IF) is performed digitally in
hardware on a field-programmable gate array (FPGA). With digital
upconversion, you can apply interpolating pulse-shaping filters (raised
cosine, root-raised cosine, and flat) to improve the efficiency of memory
usage. Because this functionality can operate on baseband waveforms
sampled as high as 25 MS/s, you can use it for up to the full 20 MHz
real-time bandwidth of the instrument.
Hardware Performance
The NI PXIe-5672 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, three-slot, 3U module. It follows industry-standard plug-
and-play specifications for the PXI Express bus, and you can seamlessly
integrate the NI PXIe-5672 with compliant PXI and PXI Express systems.
The NI PXIe-5672 features an onboard ultrahigh-stability oven-controlled
crystal oscillator (OCXO), which provides frequency stability of 20 ppb
and frequency accuracy of 50 ppb. These specifications make it useful
High-Speed Data Streaming
Combined with high-speed RAID arrays, the high-speed PXI Express data
bus and digital upconversion enable continuous RF generation from hard
disk or memory. PXI Express instruments can stream data from the host
