3. SPECTRUM ANALYZER A spectrum analyzer is a device used to examine the spectral composition of a signal. It displays a power spectrum over a given frequency range in real time. A spectrum analyzer is a device used to examine the spectral composition of a signal. It displays a power spectrum over a given frequency range in real time.

4. Types of S.A. Analog Analog Digital Digital

5. Functions of S.A. THERE ARE 3 MAIN FUNCTIONS: THERE ARE 3 MAIN FUNCTIONS: -Frequency -Frequency -Power : P(dBm)=10log(P(mw)) -Power : P(dBm)=10log(P(mw)) -Drawing of transfer functions -Drawing of transfer functions

6. Parts Maker/Peak search. Filter of resolution / (BW/AVG). Amplitude View/Trace Frequency Frequency

7. FREQUENCY It allows to fix the window of frequencies to visualize in the screen. It allows to fix the window of frequencies to visualize in the screen.

8. AMPLITUDE Is the maximum value of a signal in a point. Is the maximum value of a signal in a point.

9. VIEW/TRACE Manages parameters of measurement.It stores the maximum values in each frequency and a solved measurement to compare it. Manages parameters of measurement.It stores the maximum values in each frequency and a solved measurement to compare it.

10. BW/AVG Filter of resolution-BW/AVG Is a filter of resolution.The spectrum analyzer captures the measure by having displaced a filter of small bandwidth along the window of frequencies. Is a filter of resolution.The spectrum analyzer captures the measure by having displaced a filter of small bandwidth along the window of frequencies.

11. MAKER/PEAK SEARCH Controls the position and function of markers and indicates the value of power. Controls the position and function of markers and indicates the value of power.
