Overview
The NI PXIe-5673 and PXIe-5673E are wide-bandwidth 6.6 GHz RF
vector signal generators. Combined with the appropriate software, an
NI PXIe-5673/5673E can generate a variety of signals. With the NI Modulation
Toolkit for LabVIEW, it can generate different waveforms including AM, FM,
CPM, ASK, FSK, MSK, PSK, QAM (4, 16, 64, and 256), multitone signals, arbitrary
waveforms, and many others. In addition, you can combine these vector signal
generators with standard-specific software to generate signals for GPS, GSM/
EDGE/WCDMA, WLAN, WiMAX, DVB-C/H/C, ISDB-T, ZigBee, and others. With
NI PXIe-5673/5673E stream-from-disk capabilities, you can generate continuous
waveforms that are up to several terabytes in length.
As Figure 1 illustrates, the NI PXIe-5673 consists of the NI PXIe-5611 RF
upconverter, the NI PXI-5652 RF continuous wave (CW) source, and the
NI PXIe-5450 dual-channel arbitrary waveform generator (AWG). The NI PXI-5652
CW source uses a voltage-controlled oscillator (VCO) architecture, enabling
frequency tuning times no greater than 6.5 ms. In addition, the NI PXIe-5450
AWG 16-bit digital-to-analog converter (DAC) generates baseband I and Q
signals at data rates of up to 200 MS/s. At this sample rate, the generator is
capable of producing more than 100 MHz of RF bandwidth. Figure 2 shows
a QPSK signal with more than 100 MHz of bandwidth at 5.8 GHz. The signal
represented is configured for a symbol rate of 100 MS/s and a root raised cosine
filter with an alpha of 0.22.
Basic Architecture
The NI PXIe-5673 uses direct RF upconversion from differential baseband I and Q
signals. A block diagram of the system is shown in Figure 1.
