The user interface of the HP / Agilent N8973A 10MHz-3GHz Noise Figure Analyzer is intuitive and easy to use, with easy to find keys, which are sizedand then placed in the relevant key group according to function. Thesoft-key depths have been kept to a minimum and there are clearvisual indicators on the screen showing the current machine state.

When making noise figure measurements, a key parameter to beaware of is measurement uncertainty. The HP / Agilent N8973A NFA has a low instrumentationuncertainty to aid in accurate and repeatable measurementof manufacturers components. In addition, to aid customersin setting their components/systems specifications, Agilent has produceda web-based uncertainty calculator that will give customersinformation on how to improve and classify their measurementspecifications more accurately.

In manufacturing environments, fast measurement speed andrepeatability are critical. The HP / Agilent N8973A 10MHz-3GHz Noise Figure Analyzer includes many features that can reduce your measurement timeand increase throughput. The frequency list function allows you toselect specific points within a complete measurement span to makeyour measurement. The Sweep averaging function allows a real-timeupdate to the screen during a measurement, as you adjust the performanceof the DUT during a sweep. Both these functions, as wellas the limit line functionality for quick and easy pass/fail testing andthe additional ability to recall complete calibrated instrumentstates, increase productivity and measurement throughput.
