Moku:Go’s Frequency Response Analyzer

Compare all frequency response analyzers

Overview

Moku:Go’s Frequency Response Analyzer enables you to measure the frequency response of a system in both magnitude and phase using a swept sine output from 10 mHz to 20 MHz. Select from between 32 and 512 points per sweep and configure settling and averaging time to balance total sweep duration and signal-to-noise ratio.
