Moku:Pro’s Frequency Response Analyzer
Compare all frequency response analyzers
Overview
Moku:Pro’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 250 MHz. It has a noise floor of -135 dBm across the entire frequency range. Moku:Pro is equipped with four inputs and outputs, enabling differential or ratiometric measurements. Select from between 32 and 512 points per sweep and configure settling and averaging times to balance total sweep duration and signal-to-noise ratio.

Intuitive software and API integration
Moku: app for iPadOS provides a clear and dynamic user experience, making configuring, modifying, and debugging your setup easy.
API integration with Python and MATLAB allows straightforward automation of Moku:Pro in complex setups or for repetitive tasks.
Auto-calibration
Isolate the magnitude and phase response of the system under test by calibrating out intrinsic delays and magnitude errors introduced by cables and Moku:Pro itself.
Two-port impedance response
Precise two-port system responses, math channel enables easy graphing of a system’s output – over – input.
Available on Moku:Pro hardware
Our most powerful hardware platform to date, Moku:Pro harnesses the power of a Xilinx Ultrascale+ FPGA with higher bandwidth, lower noise, more channels, and more output power than ever before.
