Overview

The Moku:Pro 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 500 MHz. Moku:Pro is equipped with four inputs and outputs, enabling differential or ratiometric measurements. Select up to 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]
