What Is a Noise Generator?
A noise generator, also called noise generator, is mainly used to evaluate the performance of various devices and systems.
They can generate white noise or pink noise, and some are available as a function of function generators.
White noise is a noise with uniform intensity across the entire frequency range from low to high frequencies on the frequency axis.
Pink noise is noise whose components become smaller as the frequency increases.
Uses of Noise Generators
There are two types of noise generators: dedicated noise generators and noise generators that are provided as a function of function generators.
The purpose of both types of noise generators are to evaluate the functionality and performance of the device under test by generating white noise or pink noise that simulates the noise generated in the natural world.
It is used in EMI (Electro Magnetic Interference) testing, BER (Bit Error Rate) testing to evaluate whether data errors in equipment are within a predetermined range, and data transfer testing in disk drives for various BD/DVD recorders. The noise generators are also used for data transmission tests in disk drives of various BD/DVD recorders.
Principle of Noise Generators
There are various types of noise generators that output noise in the range from a few KHz to the GHz band, and the output frequency can be set linearly.
The output noise level can also be adjusted. In addition to interfaces that can be controlled via an operation panel on the device itself, there are also types that can be controlled from a PC via Ethernet.
Supplementary information on the aforementioned EMI testing using noise generators.
EMI testing generates worst-case noise that could occur in the environment where the user uses the equipment, and evaluates whether the equipment can maintain normal operation.
For example, in the case of home appliances such as televisions, it is acceptable for noise to momentarily disrupt the image on the screen or cause audio to malfunction, but the equipment must return to its original state when the transient noise is eliminated.
In other words, video and audio must be output normally, and the TV must be able to switch channels and change volume according to user operation.
This is controlled by a microcontroller for system control. Generally, microcontrollers are susceptible to noise, and in the past, momentary noise often caused them to run out of control or hang up, rendering them inoperable.
To avoid such a situation, noise generators are used to create worst-case environmental conditions, and evaluating whether the microcontroller can continue to operate normally under such conditions is an important test to improve the quality of the equipment.
