History of RF Signal Generators

Radio frequency (RF) signal generators have been around for over 100 years. In 1901, Guglielmo Marconi performed the first radio transmission via Morse code from Cornwall, England to St. Louis. John's, Canada.

In the 1940s, Hewlett-Packard created the first mass-produced generator, the model 200A audio oscillator. The first customer for this product was none other than Walt Disney, who purchased eight of them to calibrate the revolutionary sound system developed specifically for the movie Fantasia.

Radio conductor use and development can be traced back to its roots in the electronic test-and-measurement industry.

Most Common Uses of Radio Frequency Generators

Although RF signal alternators pre-date modern digital technology, they are still used in a variety of tech and science industries in several different ways. Radio frequency signal producers are needed to operate, service and set up analog radio receivers. But it's more than that. When it comes down to it, any equipment that is radio operated required this kind of generator to fully test and ensure proper operation.

Some of the most common uses include testing components, test systems, and receivers for WiFi, WiMAX, cellular communication, GPS, audio and video broadcasting, radar, satellite communication and electronic warfare.

The ones that are used today can be found in the electronics industry, including aerospace / defense electronics and wireless communications. Radar, GPS and avionics signal simulation are other common applications within the aerospace and defense electronics field.

What is Radio Frequency Signal Generation?

Many times, radio frequency generation and microwave generation are used interchangeably. They are different, however, because they operate at different pitches.

RF and microwave generators have similar features and capabilities, but are differentiated by modulation range. RF generators typically range from a few kHz to 1 GHz, although some argument it reaches 6 GHz. The signal generation can be monitored with AM radio frequencies between 535 KHz and 1605 KHz and computer LAN rates up to 2.5 GHz.

Microwave frequencies, on the other hand, have a higher rate that typically ranges from 1 MHz to 20 GHz, with some generators reaching approximately 70 GHz.

There are three types of RF signal generators: analog signal, vector signal and logical signal. Analog generators were used before the advent of modern, digital electronics.

RF conductors are one of 5 types of generators. The other types are: functional signal, arbitrary waveform, audio signal and video signal. Each of them have their own, unique use and functionality.

How Radio Frequency Generators Work

Radio frequency generators operate via a harmonic locked loop that provides adequate, accurate and stable output required for a device to operate correctly. They produce continuous wave tones within a certain range.

These sound detecting devices have become very sophisticated since their creation 100 years ago. As they have gotten more advanced, their uses have become more widespread. They are one of five types of generators that are used in a variety of industries today.

The History of the Tracfone Company

Tracfone, which is now one of the top 10 cellular providers in the US [as well as Puerto Rico and the Virgin Islands], has had an interesting history, as companies go. The company first made their mark in 1996, under the name Topp Telecom, Inc. Within a few years, they found themselves being supported by Mexican company Telmex, who bought a controlling interest [55%] in the company. By 2000, the company was split from Telmex, and began to grow exponentially, after taking on the name Tracfone. The company expanded its market share and began to bring in more business as the days went by.

Tracfone is now one of the biggest prepaid wireless companies in the United States. Because they enable users to buy prepaid minutes on a wide variety of phones [including hot brands such as LG, Motorola, Nokia, and Kyocera] they have become an excellent option for people who do not want to deal with the hassles of credit checks and long-term contracts with phone companies. This accounts for much of Tracfone’s success.

Unlike some prepaid cellular services – especially those in the past – Tracfone enables people to use some of the most popular phones and have all the options that a cell phone user with a standard-issue binding contract would have. As such, the company has built its stellar reputation on this. Nobody wants an inferior phone simply because they chose to use pre-paid services rather than be tied to a contract for anywhere from 12-24 months – or more.

In addition to being popular in the United States market, Tracfone dominates Puerto Rico and the Virgin Islands. Further, they are the most popular cellular provider in Latin America. With nearly 10 million customers and an always-growing, eager customer base, it is no surprise that the company has enjoyed so much success and continues to grow every year.

Tracfone actually provides two services – Tracfone and Net10. The two services are provided by the same company, with the same quality, though Net10 only offers GSM and CDMA services as of now. The company is expanding both of these services, as well as their TDMA service, despite most customers migrating to the former two.

Depending on the service that a Tracfone user chooses, as well as the specific phone they purchase, there are different deals that can be obtained by Tracfone customers. Some people who buy a plan with Tracfone will enjoy free text messaging, while others will pay a few cents per text. It is important to look at the fine details and choose a phone and plan that will work best for your needs. If you frequently text people, those few cents per text could add up, and it would be in your best interest to invest in a phone that enables you to text for free.

As you can see, Tracfone is a company that many people have come to rely on, and it is also a company with flexible options. It is the perfect choice for someone who wants a cell phone, but isn’t ready to commit a huge amount of money or time to a specific company, as Tracfone’s pre-paid plans do not require a contract. People can buy minutes for the phone based on both days of service as well as increments of time. This flexibility allows people to choose what sort of plan will best suit them and their specific needs as a customer. This is definitely part of what attracts people to Tracfone, and why the company has so many loyal customers. Their innovative way of dealing with cellular users by giving them many options is an excellent way for them to continue to grow and profit as a company.

The Success System That Never Fails by W Clement Stone – Book Review

Title and Author : The Success System That Never Fails by W. Clement Stone

Synopsis of Content:

Success is a system. It can be learned from those who have achieved success. In this book Stone accounts his own meteoric success going from poverty to riches and starting out in the Great Depression. He teaches what he learned from life experience, business, his mentors and others who taught him how to succeed in business.

The Success System that never fails covers the importance of selecting the correct environment for success, understanding the formula for success, thinking for oneself, the importance of taking action, and many other rules and disciplines that lead to success.

Stone teachers what he calls the three essentials for success: Inspiration to Action; Know How; and Activity Knowledge. These would also be understood as inspiration and motivation, knowledge of how to do something, and knowledge gained from experience. Each of these is essential in the pursuit of success.

He stresses the importance of proper planning and goal setting, how it takes less effort to succeed than to fail, finding and maintaining the right course to success, the importance of energy and motivation and the importance of the right team.

Stone was a devout man and he included discussions of the importance of personal faith and prayer. He also touches on what later became known as the power of attraction. He discusses the importance of developing success oriented skills such as becoming an effective public speaker, how to use your mind to achieve more, how to relate and assimilate useful information and many small steps that lead to success.

Stone's formulae for success are the traditional list of having a purpose, planning, using goals, working hard, working smart, and constant learning and improvement. While you will not find any new or revolutionary in this classic work you will find the solid success tools that have worked for millions of people for centuries and remain just as valid today as they were in 1962 when the book was written.

The examples and mentors he lists are dated a bit but they certainly illustrate his points well. To truly understand where success literature and theory is today it is useful to study its history. Stone was not a pioneer in this work but he worked with at least one such pioneer and studied others.

Readability / Writing Quality:

This book is very readable. It was ahead of its time in its careful organization. Atypical of books of that period does not contain large blocks of text but is broken down into an easy to follow outline form with many illustrations.

Notes on Author:

W. Clement Stone was one of the most successful salesman and businessman of the mid 20th century. He turned $ 100 into one of the largest insurance companies in the world and launched it in the middle of the Great Depression. He was also a student of success and a collaborator with Napoleon Hill during the 1950s.

Three Great Ideas You Can Use:

1. You can neutralize a negative emotion that limits you through properly directed action. You can change how you feel and think through your own directed action.

2. While learning and planning are critical to success nothing is more important than taking action and striking when opportunity presents itself. "Do it Now" is an axiom that will empower you.

3. If you can not save money the seeds of success will remain forever elusive. Having a budget and planning for the future are essential.
