   How does the Keysight signal analyzer work?

   • The Keysight signal analyzer preconfigures the interface. The screen displays type of calibration, frequency range, attenuation range, and number of points. Connect the RCal’s RF Out to the point in the path where the device under test (DUT) is when you take your actual measurements.

   Why does a spectrum analyzer generate noise?

   • All active electronic circuits generate noise – including spectrum analyzers. Sensitivity is the smallest signal that can be measured. The ratio, expressed in dB, of the largest to the smallest signals simultaneously present at the input of the spectrum analyzer that allows measurement of the smaller signal to a given degree of uncertainty.

   NFE creates a model of the noise of the spectrum analyzer as a function of its state. This model works for all RBWs, all attenuation settings, all paths (such as preamp on and off), even all detectors (such as peak and average), and VBW settings.

   Mar 26, 2020 · – NFE lowers the noise floor (DANL) of the SA, by measuring its own noise (no input), and subtracting that noise power. This only works with high averaging (low variance). The improvement can be up to 8-12 dB, depending on nature of signal near noise. – NF2 is “adaptive” NFE. It applies noise subtraction gradually, in proportion to ...

   For example, when measuring very small signals, you can connect external preamps directly to the DUT, increasing signal levels and mitigating problems such as attenuated signals or added noise. Today’s smart preamps automatically configure the analyzer and upload gain and frequency response, enabling precise corrections.
