![]() With the advent of digital technology, modern spectrum analyzers have been given many more capabilities. As long as we know some value of a sine wave (for example, peak or average) and know the resistance across which we measure this value, we can calibrate our voltmeter to indicate power. It is important to understand that the spectrum analyzer is not a power meter, even though it can be used to display power directly. This application note explains the fundamentals of swept-tuned, superheterodyne spectrum analyzers and discusses the latest advances in spectrum analyzer capabilities.Īt the most basic level, a spectrum analyzer can be described as a frequency- selective, peak-responding voltmeter calibrated to display the rms value of a sine wave. ![]() Inspired the creation of Blake Peterson University––required training for all engineering hires at Keysight.Īs a testament to his accomplishments and contributions, Blake was honored with Microwaves & RF magazine's first Living Legend Award in 2013.Helped launch the 8566/68 spectrum analyzers, marking the beginning of modern spectrum analysis, and the PSA Series spectrum analyzers that set new performance benchmarks in the industry when they were introduced.Authored the original edition of the Spectrum Analysis Basics application note and contributed to subsequent editions.He is warmly regarded as a mentor and technical contributor in spectrum analysis. Formany years, Blake trained new marketing and sales engineers in the “ABCs” of spectrum analyzer technology, which provided the basis for understanding more advanced technology. Inc.dedicates this application note to Blake Peterson.īlake's outstanding service in technical support reached customers in all corners of the world during and after his 45-year career with Hewlett-Packard and Keysight.
