There are different types of signal generators: audio signal generators, RF signal generators, digital signal generators and video signal generators. As is the case with other manufacturers, providers of signal generator equipment may manufacture more than one kind of signal generator, causing some overlap.

Signal generators can be useful tools when testing mobile radios, setting up CATV and preparing TV broadcasts. It is not necessary to buy the signal generators new. More than one company in the United States has a wide selection of used signal generators that are available for sale or rent. If the equipment is used, measure signal generators against factory specifications and subject them to rigorous testing. Consider these options when looking for signal generators for your business.

1. Choose audio signal generators when testing audio equipment.

2. Pick RF signal generators in manufacturing as well as research and development.

3. Utilize video signal generators when broadcasting.

Depend on the audio signal generator

Both the digital and analog audio signal generators are useful tools. Generally speaking, audio signal generators are some of the least expensive of the signal generators as well as the most compact.

I recommend: Both Tenma and April Instrument make audio signal generators that are analog with the capacity for digital correction. April Instrument has seven audio signal generators that cover the "frequency range from 0.5 to 26.5 GHz.”

Use RF signal generators for testing the return path

The RF signal generator is a handy tool for cable and Internet technicians. Their small size belies the effectiveness of the RF signal generator when testing, activating and checking the return path when installing new service for cable or Internet. The RF signal generator can also be useful when trying to measure the lack of effectiveness in the cable itself, or in the splitter.

I recommend: Many models of RF signal generators are blessedly portable, making them indispensable to the technicians who work out of their truck. Two companies that make these RF signal generators are Applied Instruments and Gigatronics.

Use video signal generators when broadcasting

Video signal generators help to test the effectiveness of the video signal.

I recommend: The Harris Corporation makes video signal generators. As the price for video signal generators are more than for other signal generators, your company can benefit from getting these indispensable machines through companies like Rohde & Schwarz, which have used signal generators for sale.
