How to check the frequency using a Multisim spectral analyzer

How to check the frequency using a Multisim spectral analyzer

Because the spectrum analyzer performs spectrum analysis through FFT (Fast Fourier Transform), after clicking "Run" and then clicking the "star" button at the bottom of the panel, you need to wait until the resolution displayed below the "Resolution freq" box When it is. As you would expect, Multisim allows users to analyze signals in the frequency domain. This video discuss frequency analysis using multisim, and procedure for verifying if the response is according to what the theory predicts.

Processing of Polarization-Maintaining Fiber Conical Lenses

Processing of Polarization-Maintaining Fiber Conical Lenses

The lenses, which are able to couple more than 7W of the light from a laser diode into the fiber, are made by micromachining an aspheric surface over the core region of the fiber with a CO, laser, as the fiber spins and is directed by computer about the beam. Polarization-maintaining single- mode fibers (PM fibers) are rotation-ally non-symmetric because of inte-grated stress elements, for example, that break the degeneracy of the two principle states of polarization (SOP). Custom FiberPM Mark Conical Lensed Fiber is a fiber optic component with a conical-shaped lens at one end. It offers precise polarization control, enabling efficient polarization maintenance. There are several recurring issues when dealing with the evaluation of the optical performance of PM elements, the key ones being the characterization methods, and the correct interpretation of the measurement outcomes.
