3 terms

Real-time spectrum analyzer captures 100% of the narrowest pulse duration: 100% amplitude accuracy When the pulse width of the input signal goes from wide to narrow, the difference between the signal amplitude and the amplitude in the continuous wave state: The rms amplitude of the ADC (analog-to-digital converter) carrier frequency (maximum signal component) within the real-time analysis bandwidth The ratio of the root mean square value of the maximum noise component, usually expressed in dBc (relative to the carrier frequency amplitude) or dBFS (relative to the carrier frequency amplitude) expressed in the full-scale range of the ADC): 3:4 Waterfall chart spectrum time frequency diagram Spectrogram A display mode of a real-time spectrum analyzer, in which frequency is represented by the x-axis, time is represented by the y-axis, and power is represented by Indicated by color: Corresponds to the digitizer and IF bandwidth of the real-time spectrum analyzer, enabling seamless real-time capture of frequencies rate span: Note: The real-time analysis bandwidth of a real-time spectrum analyzer is similar to the sweep width of a swept frequency spectrum analyzer: In the frequency domain of a real-time spectrum analyzer, a triggering method uses a preset frequency-amplitude threshold as the trigger condition: Amplitude-frequency characteristics within the maximum real-time analysis bandwidth: ......
