27 GHz Low Phase Noise Reference Source The Fluke Calibration 27 GHz 96270A RF Reference Source is the simplest, most accurate and cost effective single instrument for calibrating spectrum analyzers and RF power sensors and more. Its precision signal level and attenuation, high signal purity and precision low distortion modulation make this reference source clearly superior to the general-purpose signal generators that are often used to calibrate spectrum analyzers, RF power sensors, attenuators, and similar instruments. Its low phase noise provides superior phase noise performance. Unlike many RF calibration solutions, the 96270A is designed specifically for RF calibration, with a calibration oriented user interface that makes it easy to learn and operate. The 96270A simplifies and speeds up calibration procedures, reduces opportunities for operator errors, and greatly simplifies RF metrology. At the core of an RF and microwave calibration system, the 96270A covers more than 80 % of the test points required for calibrating almost all spectrum analyzers of any frequency range. For many spectrum analyzer models operating below 27 GHz, you only need a 96270A to perform the entire calibration. You canâ€™t simplify much more than that! Automated with MET/CALÂ® Calibration Management Software, the 96270A reduces complexity and calibration times, improving efficiency and increasing capacity over manual methods.
