Overview
The National Instruments PXI-5660 is a modular RF signal analyzer optimized
for automated test. It provides fast RF measurements in a compact, 3U PXI
package. The NI PXI-5660 features a wide instantaneous bandwidth, highly
stable timebase, and vector measurement capabilities that make it ideal
for applications such as RF component and commercial electronic test
applications. The PXI-5660 is shipped with the National Instruments
Spectral Measurements Toolkit, which offers a breadth of spectral
analysis functions including in-band power, adjacent-channel power,
and power and frequency-peak-search ability. Additionally, it provides
vector capabilities, such as 3D spectrograms, I/Q data for modulation
analysis, and analog modulation analysis functions.
Hardware
The PXI-5660 hardware consists of a 2.7 GHz downconverter and a
high-spectral-purity digitizer.
Analog Input
With the PXI-5660, you can acquire a wide range of signal levels, from
+30 dBm to less than -130 dBm and achieve up to 50 dB of input
attenuation, selectable in 10 dB steps.
Frequency Characteristics
The PXI-5660 offers outstanding frequency capabilities over its
operating range of 9 kHz to 2.7 GHz. It provides a typical noise density of
<-140 dBm/Hz and more than 80 dB of intermodulation spurious-free
dynamic range. Typical phase noise is <-94 dBc/Hz at a 10 kHz offset.
Superior Measurement Throughput
The most significant advantage of the PXI-5660 over traditional RF
instrumentation is measurement throughput. Figure 1 illustrates the
difference in throughput between the PXI-5660 and a traditional analyzer.
Two comparisons are shown. One graph is a spectral sweep that illustrates
the advantages of the wide instantaneous bandwidth of the downconverter.
The other graph is an in-band power measurement comparison that shows
the throughput advantages of the PXI-5660 as a whole.
