RF List Mode support for NI PXIe-5673E

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.

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.

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.
