A spectrum analyzer is the most convenient tool for noise measurements, ... There was a problem with this circuit, ... This is where a not-too-low equivalent series resistance ...

[Ryan] wanted a spectrum analyzer for his audio equipment. Rather than grab a micro, he did it the analog way. [Ryan] designed a 10 band audio spectrum analyzer. This means that he needs 10 band-p… ...

One of my favorite companies, Mini-Circuits, developed a (really!) low-noise, broad band, preamp (model PSA4-5043+) earlier this year for use as a front-end amplifier for mobile telecom applications, ...

Unfortunately, a spectrum analyzer that's primarily for RF typically presents an input impedance of 50Ω, a heavy load when you apply it to most high-impedance analog circuits. You can improvise a ...

Spectrum Analyzer BASICSThere are many ways to look at the world, and many ways to look at electronic signals. Many fundamental instruments, such as voltmeters and oscilloscopes ...

A Rydberg receiver and spectrum analyzer detects a wide range of real-world radio frequency signals above a microwave circuit including AM radio, FM radio, Wi-Fi and Bluetooth.

Wi-Fi techs have two choices when tracking down interference: guessing or using an RF spectrum analyzer. Nuts About Nets just made using an RF spectrum analyzer a better choice.
