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.

Spelling difference.... :)
Distortion.
the frequency difference between the transmitter and the receiver without any noise or distortion
Pincushion distortion and barrel distortion are both types of optical distortions that occur in images. Pincushion distortion causes the image to appear pinched inwards towards the center, while barrel distortion causes the image to bulge outwards towards the edges. The main difference between the two is the direction in which the distortion occurs - pincushion towards the center, and barrel towards the edges.
the wave length
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
