Question

a. List the requirements of laboratory type signal generators. 

b. Write a note on sine-wave generator, square wave generator, pulse generator, function 

generator, and Lab VIEW.

c. Illustrate in detail IEEE488 Electrical Interface.

Answer 1

a. The frequency range, output power, phase noise, frequency accuracy, and modulation types of RF signal generators are all significant in determining generator functioning.

b. Sine wave: In most cases, a function generator may also work as a sine wave generator. This is the conventional waveform with a sinusoidal shape that oscillates between two levels. One of the most typical applications is to utilize the function generator as a sine wave generator. Sine waves are common in testing applications.

Square wave:The square wave is another popular waveform. It is made up of a signal that alternates between high and low levels. This test device, when used as a square wave generator, is a highly helpful source of a basic digital waveform.

Pulse: A pulse waveform is another sort of waveform that a function generator may generate. It is essentially the same as a square wave, however the mark space ratio is far from 1:1. This type of waveform is frequently utilized in digital applications.

A function generator is often a piece of electronic test equipment or software that is used to create various sorts of electrical waveforms across a wide frequency range. The sine wave, square wave, triangle wave, and sawtooth patterns are some of the most popular waveforms created by the function generator.

LabVIEW is systems engineering software designed for applications requiring test, measurement, and control as well as quick access to hardware and data insights.

IEEE-488 is an Institute of Electrical and Electronics Engineers (IEEE) standard for a parallel interface designed by Hewlett-Packard that is used to link computers to measuring sensors and test equipment in a laboratory or industrial environment for automatic data collecting.
