Overview

The Moku:Lab 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 200 MHz. Select from between 32 and 8192 points per sweep and configure settling and averaging times to balance total sweep duration and signal-to-noise ratio.[/lq_Video_image_text_top_bottom]
