Moku:Lab’s Frequency Response Analyzer can be used to measure a system’s frequency response from 10 mHz up to 120 MHz.

Features

Stimulate the device under test
Linear or logarithmic swept sine output

Configurable math channel
Math channel to add, subtract, multiply or divide response functions as they are acquired

Rapid phase, amplitude vs frequency measurements
Use cursors and markers to measure exact values on the plots

Wide range of settling and
averaging times
Measurement averaging and settling times are highly configurable

Rapid data sharing
Easily save data and upload to the cloud or Dropbox in common formats

2 outputs and 2 inputs are independently configurable
Probe two systems simultaneously, or one system at two points

Live Bode plot updates; or pause for analysis
Monitor the magnitude and phase on the interactive Bode plot

One touch calibration
Save a calibration trace to compare systems or remove spurious cable shifts

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
measurements

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

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:Lab itself.
