Overview
NI PXIe-5663 and PXIe-5663E 6.6 GHz RF vector signal analyzers offer wide
instantaneous bandwidth optimized for automated test. Combined with high-
performance PXI controllers and the high-speed PCI Express data bus, these
modules can perform common automated measurements significantly faster
than traditional instruments. You can use an NI PXIe-5663/5663E as either
a spectrum analyzer or vector signal analyzer with NI LabVIEW or
LabWindows/CVI software. In addition, you can use both the NI PXIe-5663
and PXI-5663E modules with the NI Modulation Toolkit for LabVIEW to analyze
custom and standard modulation formats.
When combined with NI or third-party analysis toolkits, the NI PXIe-5663/5663E
can perform measurements for a broad range of communications standards such
as GSM, EDGE, WCDMA, WiMAX, LTE, Bluetooth, WLAN, DVB-C/H/T, ATSC,
and MediaFLO. Because all measurements are software-defined, you can simply
reconfigure the measurements using standard specific toolkits. With these
toolkits, the NI PXIe-5663/5663E modules provide a low-cost solution to high-
performance RF measurements.

Figure 1. Block Diagram of an NI PXIe-5663
As illustrated in Figure 1, the NI PXIe-5601 RF downconverter module
downconverts an RF signal to an intermediate frequency (IF). The local oscillator
(LO) source is an NI PXI-565x RF continuous wave (CW) source, which uses a
voltage-controlled oscillator (VCO) architecture for fast-frequency tuning speeds.
Using a VCO, the NI PXIe-5663 is able to retune and measure signals in 11 ms
or less. The NI PXIe-5622, which is used as an IF digitizer, features a 16-bit,
150 MS/s analog-to-digital converter (ADC).
The NI PXIe-5622 is based on a common synchronization architecture found in
many NI PXI modular instruments. Thus, you can share timing and trigger signals
between the NI PXIe-5663 and other PXI modular instruments.
Basic Architecture
As single-stage RF vector signal analyzers, the NI PXIe-5663/5663E modules
are ideally suited for automated RF measurements when directly cabled to the
device under test (DUT). You can use an NI PXIe-5663/5663E to perform fast and
accurate RF measurements in design validation and manufacturing
test applications.
Enhanced Architecture
The NI PXIe-5663E (E for enhanced) provides additional performance and
features including RF List Mode support and configurable loop bandwidth for
decreased tuning times. Like the NI PXIe-5663, the NI PXIe-5663E comprises
three modular instruments. The enhanced NI PXIe-5601 RF downconverter
module downconverts an RF signal to an IF signal, which is digitized with the
