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. 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. Throughput Benchmarks Spectrum Sweep: 5 to 7X Improvement Hardware The PXI-5660 hardware consists of a 2.7 GHz downconverter and a high-spectral-purity digitizer. RBW = 10 kHz RBW = 30 kHz 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. 0 5 10 15 20 25 30 Measurements per Minute Traditional Instrumentation NI RF Signal Analyzer Performance Benchmarks In-Band Power: 30 to 200X Improvement 800 kHz 320 kHz 160 kHz 0 1 M 2 3 S 4 d 5 Traditional Instrumentation NI RF Signal Analyzer Frequency Characteristics The PXI-5660 offers outstanding frequency capabilities over its operating range of 9 kHz to 2.7 GHz.
