Moku:Lab’s Frequency Response Analyzer

Compare all frequency response analyzers


Moku:Lab’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 120 MHz. 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.

Software & APIs

Wirelessly configure and monitor the magnitude and phase of your system’s transfer function, all from intuitive Moku software for iPad, Windows, or with APIs for Python, MATLAB, and LabVIEW.

Freedom in the lab when you need it

Monitor the interactive Bode plot for live updates from anywhere in the lab. With Moku software for iPad, there is no need to be tethered to your bench.

Try it in demo mode


Isolate the magnitude and phase response of the system under test by calibrating out intrinsic delays and magnitude errors introduced by cables and Moku:Lab itself.

Two-port impedance response

Precise two-port system responses, math channel enables easy graphing of a system’s output – over – input.
