Overview

Frequency Characteristics

The National Instruments PXI-5661 is a modular 2.7 GHz RF vector signal

analyzer with wide real-time bandwidth, optimized for automated test in a

The PXI-5661 provides outstanding frequency characteristics over its

operating range of 9 kHz to 2.7 GHz. It offers a typical noise density of

compact, 3U PXI package. It is ideal for high-throughput RF acquisition and <-140 dBm/Hz, extendable to -165 dBm/Hz with a PXI-5690 preamplifier,

measurements. The 20 MHz wide onboard quadrature digital downconverter and up to 80 dB of intermodulation spurious-free dynamic range.

(DDC) significantly reduces the required load size and the time Needed to

transfer waveform data to the host controller or PC. This functionality

is ideal for engineers who require data streaming with rapid response time

for software-defined radio (SDR), real-time signal processing, or faster

transfer times for spectral monitoring applications. The module is also

compatible with Conduant StreamStor devices, enabling terabyte recording.

The NI PXI-5661 RF analyzer also includes a burst power trigger ideal

for communications applications and signal intelligence. The PXI-5661

features a highly stable timebase and flexible software tools, including

Express VIs for National Instruments LabVIEW.

Typical phase noise is <-94 dBc/Hz at a 10 kHz offset.

Superior Measurement Throughput

The most significant advantage of the PXI-5661 over traditional

RF instrumentation is measurement throughput. Figure 1 illustrates the

difference in throughput between the PXI-5661 and a traditional analyzer.

Two comparisons are shown. One graph is a spectral sweep that illustrates

the advantages of the wide real-time bandwidth of the downconverter.

The other graph is an in-band power measurement comparison that

shows the throughput advantages of the PXI-5661 as a whole.

The NI Spectral Measurements Toolkit for LabVIEW and

LabWindows/CVI accompanies the PXI-5661, providing common

measurements such as power spectrum, peak power and frequency, in-band

power, adjacent-channel power, and occupied bandwidth. Additionally,

it offers vector capabilities, such as 3D spectrograms, I/Q data for

modulation analysis, and analog modulation analysis functions for LabVIEW.

You can also use the PXI-5661 with the NI Modulation Toolkit to analyze

custom and standard modulation formats.

Hardware

The PXI-5661 consists of a 2.7 GHz downconverter and a

high-spectral-purity digitizer.

Analog Input

The PXI-5661 can acquire a wide range of signal levels, from +30 dBm

to less than -130 dBm, and provides up to 50 dB of input attenuation,

selectable in 10 dB steps.
