When speaking with a sales associate from a test equipment company I learned that one of the most important things to consider when shopping for function generators and any other used test equipment is brand loyalty. While different electronic manufacturers specialize in different testing equipment, it is essential to work with the right company for your specific needs.

You can find a listing of the most popular function generators by logging onto the Internet. Most of the test equipment suppliers on the market today provide a complete listing of their available inventory online. When you purchase used test equipment you not only save up to 70% off of the original price of new equipment, but you also receive your equipment much more quickly than you would if you bought it new. One sales associate told me you can expect to receive used equipment in less than a week's time, while new equipment can take between four and six weeks to receive from the factory.

What to Consider When Shopping for Function Generators

Function generators are diagnostic tools that help to measure frequency, amplitude and phase modulation. This particular type of signal generator produces square waves that help engineers and technicians troubleshoot potential problems in the system. These professionals read the information contained in the output signals to determine the root of electrical malfunction.

When searching for a function or signal generator it is important to consider the certification requirements and industry standards for accuracy. When shopping for these devices it is important to describe your specific accuracy needs. You will also want to consider the number of input channels required to conduct your test with accuracy. You should also consider frequency range and frequency accuracy for testing equipment.
