National Instruments 783156-01 Vector Signal Analyzer.
The National Instruments 783156-01 (Model Name PXIe-5668R) is a high performance Vector Signal Analyzer (VSA) designed for demanding applications such as wireless communication, RF integrated circuit characterization, radar testing and spectrum monitoring. It operates within a frequency range of 20 Hz to 14 GHz that provides comprehensive coverage for modern RF applications. The VSA's tuning resolution is as fine as 533 nHz and offers the precise frequency selection necessary for detailed signal analysis. This VSA features an equalized bandwidth of up to 765 MHz depending on the configuration. Standard configurations provide 80 MHz bandwidth with optional upgrades available for 200 MHz, 320 MHz, and 765 MHz bandwidths. The resolution bandwidth ranges from less than 1 Hz to 320 MHz depending on the chosen configuration which allows for accurate spectral analysis over a broad range of signal types.
The 783156-01 incorporates several key modules: the PXIe-5606 RF Signal Downconverter, PXIe-5624 IF Digitizer, and PXIe-5653 RF Analog Signal Generator. These modules work together to ensure high fidelity in signal capture and measurement with excellent spectral purity and boasting single sideband (SSB) phase noise as low as -140 dBc/Hz at 1 MHz offset. The model is housed in a compact 3U, 7 slot PXI Express form factor that makes it well suited for integration into existing test setups. The amplitude range capabilities of this National Instruments 783156-01 VSA extend from the average noise level up to + 30 dBm along with electronic RF input attenuation adjustable from 0 dB to 30 dB in 1 dB steps. The device offers superior amplitude accuracy along with frequency response deviations as low as ± 0.06 dB in the 10 MHz to 100 MHz range.
The 783156-01 also supports complex modulation analysis with application specific modulation quality metrics such as OFDM EVM for WLAN 802.11ac signals. It provides detailed spurious response analysis, including residual spurs and higher order RF responses. The unit's quick tuning times and preselector tuning combined with multi instrument synchronization capabilities make it an ideal choice for high volume manufacturing tests and phase coherent MIMO testing.
