[Test & Measurement] Agilent Adds Source-Corrected NF Measurements Jack Browne | ED Online ID #16799 | September 13, 2007
Agilent Technologies has announced the availability of source-corrected noise-figure (NF) measurement capability for its PNA-X vector network analyzer (VNA). By using the company's ECal electronic calibration module as an impedance tuner, the VNA can make vector-error- corrected noise-figure measurements based on the highly accurate cold-source technique. The ECal module helps the analyzer find the optimum source impedance for noise measurements on a device under test, such as a low-noise amplifier (LNA), at frequencies from 10 MHz to 26.5 GHz. It also enables measurements with a single connection, saving measuring time and wear on test connectors. The error-corrected approach features fast measurement time of 42 ms/point and surpasses the accuracy provided by Y-factor-based NF analyzers or spectrum analyzers used for NF measurements. The PNA-X can also be specified with an integrated second source, signal combining network, and internal pulse generators for a variety of measurements on amplifiers and frequency-translation devices.
