A distortion analyzer is an electronic test instrument that measures the accuracy of an electronic circuit at reproducing a wave.For instance, an audio amplifier might have a sine wave input to it, and the distortion analyzer measures how close the output is to a sine wave.If the output is clipped, the wave will be distorted, and the analyzer will measure the amount of harmonics present.mplifiers will frequently have a Total Harmonic Distortion plus Noise specification which is an accurate term for the quantity measured by a distortion analyzer. There are many manufacturers of distortion analyzers. The Hewlett-Packard models 331a and 333 are laboratory standard instruments.
This is done at the end of the anesthesia or if the animal is at too deep of a plane of anesthesia during the surgery. Vaporizer-The vaporizer converts the liquid anesthetic to a gas state and adds controlled amounts of the gas anesthetic to the oxygen that is flowing through the machine.t is at this point that the system changes. The nonrebreathing system does not have each of the parts of a rebreathing system. It does have: Vaporizer-The vaporizer converts the liquid anesthetic to a gas state and adds controlled amounts of the gas anesthetic to the oxygen that is flowing through the machine.
