Noise Figure Measurements with Vector Correction
S93029A - Keysight Technologies
The S93029A noise figure application enables high-accuracy noise figure and noise-power measurements of amplifiers, frequency converters, and mixers, utilizing Keysight's unique vector-source-correction technique that uses a source-impedance tuner to remove the effects of imperfect system-source match. This approach yields accuracy that surpasses that provided by the Y-factor method and other cold-source implementations, especially for in-fixture, on-wafer, and automated-test environments. A scalar-calibrated method is also available that offers less accuracy, but is faster and does not require an impedance tuner.
