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. 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 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.

PXI-5660 Performance Benchmarks 3 S 4 d 5 2.7 GHz RF Signal Analyzer Ultrahigh-Stability Timebase The PXI-5660 offers an extremely stable timebase with frequency stability of ±20 ppb and frequency accuracy of ±50 ppb, making it useful for a range of automation applications. Accuracy The noise and distortion characteristics of the PXI-5660 are stable and repeatable over time and a wide range of temperature. For example, with a 1 MHz measurement bandwidth, a -10 dBm signal has a repeatability of less than 0.1 dB, with a resolution bandwidth (RBW) of 1 kHz and number of averages equal to 10. The PXI-5660 uses a software compensation method that reduces amplitude error to less than 0.2 dB over a 20 °C change. Applications Acquisition Memory General-Purpose Test Spectral analysis Semiconductor ATE Ultrasound/radar/lidar RF component characterization Military/aerospace Siglnt Commercial Electronics Test Cable modem Mobile phones and pager Wireless LAN and Bluetooth Commercial radio Digital television The PXI-5660 includes up to 64 MB of onboard memory, delivering acquisition of up to 32 million real 16-bit samples or 16 million complex 16-bit samples. The PXI-5660 uses the bus master capability of the NI MITE ASIC to move data to computer memory at much higher speeds – up to 10 times faster – than traditional instrument interfaces. Because this ASIC performs memory management Table 1. Applications for the PXI-5660 functions usually handled by the host CPU, you can devote all the computer power of the host CPU to data analysis. centered at 900 MHz, the rate at which you store samples can be as low as 250 kS/s. Calibration National Instruments calibrates the amplitude accuracy of the analog input of the downconverter and digitizer modules. Temperature variations are calibrated and corrected during normal operation, resulting in very high stability and repeatability. The modules are shipped with NIST-traceable and ISO-9002-certified calibration certificates. Visit ni.com/calibration for more information about calibration services.

SMT plugs directly into NI LabVIEW and LabWindows/CVI software to offer high-level measurement functionality. For a complete list of measurement functions, refer to Table 2. The driver software provides a driver-level interface and integrates with LabVIEW and LabWindows/CVI. Table 2. Spectral Measurements Toolkit Functions Clock Generation and Triggering The 10 MHz reference clock on the PXI-5660 can synchronize to any one of three sources – the onboard high-precision OCXO reference clock, an external reference clock, or the PXI backplane. Using the PXI backplane, you can synchronize two or more PXI-5660 signal analyzers with each other and other PXI modules without using cables. You can synchronize the PXI-5660 to an external source using front-panel connectors. It can import and export TTL triggers from the PXI trigger bus, the PXI star trigger line, or the front-panel SMB connector. The PXI trigger bus greatly simplifies synchronizing RF measurements with other PXI modules such as digital multimeters, audio analyzers, and machine vision modules. Digital Downconversion and Decimation With the digital downconversion (DDC) functionality of the PXI-5660, you can acquire narrowband signals at much less than the full digitization rate. By downconverting channels of up to 1.25 MHz bandwidth to baseband, the PXI-5660 dramatically reduces the sampling rate necessary to acquire these signals. This feature results in dramatic throughput improvements for narrowband applications. For example, if you want to acquire a signal with a 200 kHz bandwidth Ordering Information NI PXI-5660 32 MB ................................................................................778284-01 64 MB ................................................................................778284-02 Includes modules, cables, NI-TUNER, NI-SCOPE, and the NI Spectral Measurements Toolkit.
