It is ideal for high-throughput RF acquisition and measurements. The 20 MHz wide onboard quadrature digital downconverter (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. 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. 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 <-140 dBm/Hz, extendable to -165 dBm/Hz with a PXI-5690 preamplifier, and up to 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-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. 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. Figure 1. PXI-5661 Performance Benchmarks 2.7 GHz RF Vector Signal Analyzer with Digital Downconversion Ultrahigh-Stability Timebase The PXI-5661 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-5661 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, where resolution bandwidth (RBW) = 1 kHz and number of averages = 10. The PXI-5661 employs amplitude equalization that reduces amplitude error to less than 0.2 dB over a 20 °C change. Acquisition Memory The PXI-5661 includes up to 256 MB of onboard memory. With this memory, you can acquire up to 128 million real 16-bit samples, or 64 million complex 16-bit samples. The PXI-5661 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 functions usually handled by the host CPU, all the computer power of the host CPU can be devoted to data analysis. Clock Generation and Triggering The 10 MHz reference clock on the PXI-5661 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-5661 units with each other and other PXI modules without using cables. You can synchronize the PXI-5661 to an external source using front panel connectors. The PXI-5661 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. The PXI-5661 also includes a burst power trigger with which you can trigger an acquisition based on the power within the configured modulation bandwidth. Digital Downconversion and Decimation With the digital downconversion (DDC) functionality of the PXI-5661, you can acquire signals at much less than the full digitization rate. By downconverting channels of up to the full 20 MHz bandwidth to baseband, the PXI-5661 dramatically reduces the sampling rate necessary to acquire these signals. This feature results in dramatic throughput improvements for many applications. For example, if you want to acquire a signal with a 200 kHz bandwidth centered at 900 MHz, the rate at which samples are stored can be as low as 250 kS/s. Digital downconversion and decimation in combination with the high-throughput PXI backplane provide RF and communication data streaming to a controller or PC for real-time signal processing and analysis or record and playback applications. 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. Software The National Instruments Spectral Measurements Toolkit and NI-RFSA driver software are included with the PXI-5661. The Spectral Measurements Toolkit plugs directly into LabVIEW and LabWindows/CVI to offer high-level measurement functionality. For a list of measurement functions, refer to Table 1. The driver software provides a driver-level interface and integrates with LabVIEW and LabWindows/CVI.
