How does a spectrum analyzer work?

The spectrum analyzer measures the radio noise floor and analyzes how close two signals can be while still being resolved into two separate peaks. It uses a linear scale for signal frequency and a logarithmic or decibel scale for amplitude.

How do you find the spectral peak?

For a particular spectral peak, the dichroic ratio R is defined by the relationshipR = A⊥/A∥where A⊥ and A∥ are the absorption of the LB films when the light is polarized perpendicular or parallel to the dipping direction, respectively.

What does a spectrum analyzer show?

A spectrum analyzer measures the magnitude of an input signal versus frequency within the full frequency range of the instrument. The primary use is to measure the power of the spectrum of known and unknown signals.

What is peak detection?

Definition: Peak detector circuits are used to determine the peak (maximum) value of an input signal. It stores the peak value of input voltages for infinite time duration until it comes to reset condition.
