Software integrations

Wirelessly configure and monitor the magnitude and phase of your system’s transfer function, all from an intuitive iPad interface, the Windows App (beta), or with integrations for Python, MATLAB, and LabVIEW.

Measurements made easy

Quickly measure key features in your system’s magnitude and phase response with draggable cursors.

Fine tune your

Optimize measurement quality by configuring the Frequency Response Analyzer’s output voltage level, sweep range and scale, averaging time and settling time.


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.
