주요 특징 및 사양

  • Measure noise figure of amplifiers or up-converters at frequencies up to 26.5 GHz, or measure down-converters with inputs up to 43.5/50 GHz, and outputs at 26.5 GHz or below
  • With a single connection, obtain fast, high accuracy measurements of S-parameters, conversion gain/loss, noise figure, compression, IMD, harmonics, and more
  • Surpasses the accuracy provided by Y-factor-based noise-figure analyzers or spectrum analyzers
  • Reduced measurement complexity speeds test set-up times and improves time to market
  • Fast sweep times improve throughput in manufacturing

Option H29 adds 26.5 GHz low-noise receivers to four-port N5244A/45A PNA-X Series microwave network analyzers with Option 423. The option includes firmware for making high-accuracy noise figure measurements of amplifiers, frequency converters, and mixers, utilizing Keysight´s unique source-correction technique. Using the PNA-X and a Keysight ECal module configured as an impedance tuner, the effects of imperfect system-source match are removed, greatly improving the accuracy of the cold-source technique. This approach surpasses the accuracy provided by the Y-factor method. For fully corrected noise figure measurements, this option requires an N4693A ECal module (m-f recommended) and a 346-series noise source (both must be ordered or supplied separately). A scalar calibration choice is also available that offers less accuracy, but is faster and does not require the ECal module used as an impedance tuner. For measurements of mixers and converters, a power meter is also required. The noise source and power meters are only used during calibration of the analyzer. For calibration of the analyzer, an additional ECal or mechanical calibration kit is required (also must be ordered or supplied separately).

For noise figure measurements up to 50 GHz using the standard receivers, see Option 028
