The spectrum analyzer is used to do distortion analysis to the signal. Due to the fact that we don't have a pure generated signal. In reality, there must be some distortion. The distortion analysis is important in the communication field as well as in electronics.
Distortion.
the frequency difference between the transmitter and the receiver without any noise or distortion
The output waveform will be limited to the difference between the supply and ground (or between the positive and negative supplies). This causes distortion of the output waveform.
The difference in meaning between 'scope' and 'need' is as follows: the former denotes 'range' or 'spectrum' while also frequently implying vision -- or perception of some kind. By contrast, 'need' denotes 'lack' or 'unsatisfied desire.'
Mechanical stress is due to the resistance offered by various materials against physical distortion or damage. Thermal stress is caused due to the expansion of materials due to the variations in temperature with respect to reference value.
spectrum analyser is single channel and cannot find ratio of phase and magnitude
The difference between dry chemistry analyzer and the chemistry analyzer is the reagents used.
an oscilloscope give amplitude v/s time display of a wave, whereas the spectrum analyzer gives amplitude v/s frequency display. the oscilloscope gives distribution of energy in wave with respect to time whereas the spectrum analyzer displays frequency components of a wave and their amplitudes.

An analyst is a person who analyzes things. An analyzer is a machine the analyst uses to perform his or her analyses.
shape will be changed
Spelling difference.... :)
simulators and analyzer are used in devices calibration simulator simulates what the device measures , i.e device measures analyzer measures what the device measures , i.e analyzer measures Eng. Mohammed Sameer Biomedical Engineer eng.m.sameer@gmail.com
Distortion.
The spectrum of sunlight is continuous while for hydrogen is line spectrum (discontinuous)
The difference between continuous spectrum and the atomic emission espectrum of an element is that in emission spectrum, only certain specific frequencies of light are emitted while in a continuous spectrum, a continuous range of colors are seen in the visible light.
Audio frequency spectrum is measured in Hertz's (Hz) and tells the range of audible audio. The human hearing range is usually 20-20000Hz, but especially the audibility of the top end of the spectrum declines with age. Most software analyzers measure between 0 Hz and 16000-24000kHz
