Measuring Filter Characteristics Using the SSA3000X Plus / SSA3000X-R / SVA1000X Spectrum Analyzer

June 22, 2021

A filter is a universal, two-port, frequency-selective device used in a wide variety of electronic circuits and applications. A low-pass filter is one that passes signals with a frequency lower than a certain cut-off frequency while attenuating the higher frequencies. Low-pass filters are often used in radio transmitters, audio devices, and communication systems. They can … Continued
