TECHNOLOGY SURVEY A SAMPLING OF SPECTRUM ANALYZERS

摘要

This month's technology survey looks at benchtop and portable spectrum analyzers. The first function the spectrum analyzer accomplishes is providing a complete picture of the RF environment. A spectrum analyzer can measure frequency, power, harmonics, bandwidth and other spectral components of an RF signal that cannot be easily measured in the time domain. It can also perform typical time domain measurements, like signal repetition rate and pulse rise and fall time measurements. A typical spectrum analyzer display will show frequency on the horizontal axis and amplitude on the vertical axis.
