RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

June 1st, 2021 - Vista, California - Axiom Test Equipment, an electronic test equipment rental and sales company has published a new blog post that informs people on how to select the best signal source for a job. A suitable test signal source should provide signals with accurate, repeatable characteristics that can properly exercise the equipment under test (EUT), such as an amplifier, antenna, or filter. Depending upon what is being tested, the requirements for the test signals will differ, such as frequency and power levels.

Signals are generated in different forms, including continuous wave (CW), pulsed, and differential pairs that form phase-modulated signals. Generators may provide single-frequency outputs, sweep signals across a range of frequencies, or even "hop" quickly from one frequency to the next to create patterns of mixed signals or waveforms to emulate a communications channel. Essential performance parameters for signal and waveform generators include frequency range, frequency resolution, output power, and tuning or switching speed. Additional parameters include swept bandwidth and sweep speeds for swept signal generators and pulse width and pulse rise/fall time for pulse generators. The importance of each parameter will depend upon how a test signal source is used. For example, a signal generator with fast frequency tuning may be ideal for high-volume production testing but it may lack phase-noise performance.

Learn more about how to pick the appropriate test signal source for different requirements of frequencies and power levels by reading the full blog post on Axiom's Website.

Signal generation often precedes signal analysis and, as signals used in electronic products grow more complex and even higher in frequency, generating test signals becomes more critical for evaluating those products. Except in analyzers with built-in signal sources, creating test signals is usually the task of a signal generator or arbitrary waveform generator (AWG). Testers currently have a wide choice of test equipment, from small, economical units to more sophisticated, larger signal sources. Selecting the best signal source for a job usually depends on the job. By mapping out test signal performance requirements for an application, the challenge of finding an optimal test source can be greatly simplified.

One goal for any test signal source is to provide signals that emulate those normally processed by an electronic product or system to be tested, whether it is an audio amplifier, a cellular telephone, or a radar. A suitable test signal source should provide signals with accurate, repeatable characteristics that can properly exercise the equipment under test (EUT), such as an amplifier, antenna, or filter. Depending upon what is being tested, the requirements for the test signals will differ, such as frequency and power levels.

Which Generator Type?

Modern signal and function generators build upon a variety of technologies, including analog frequency conversion, frequency multiplication, and digital signal synthesis, to create test signals. Signals are generated in different forms, including continuous wave (CW), pulsed, and differential pairs that form phase-modulated signals. Generators may provide single-frequency outputs, sweep signals across a range of frequencies, or even "hop" quickly from one frequency to the next to create patterns of mixed signals or waveforms to emulate a communications channel. In AWGs and digital waveform generators, higher sampling rates and greater numbers of digital bits yield higher precision when the bits are converted to analog waveforms. More memory will also be needed for each channel to store representations of complex waveforms...
