Frequency Response Analyzer

The Moku 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. With up to four inputs and outputs available for Moku devices, it’s easy to enable 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.

Stimulate the device under test for complete characterization

Apply a swept sine signal to your device under test to view the system response in magnitude and phase. Independently configure up to four inputs and four outputs, allowing you to probe up to four systems simultaneously, or one system at four points

One-touch normalization to see the real response of your device under test

Isolate the magnitude and phase response of the system under test by normalizing out intrinsic delays and magnitude errors introduced by cables and Moku:Pro itself. Save a normalization trace to compare systems or remove spurious cable shifts.

Moku:Pro Frequency Response Analyzer Bode plot updates

Live Bode plot updates for real-time analysis

Monitor the magnitude and phase on the interactive Bode plot, allowing you to make measurements across fundamental and harmonics to characterize nonlinear effects.

Frequency response analyzer configurable math channel view

Configurable math channel for enhanced flexibility

Use the math channel to add, subtract, multiply, divide, or calculate arbitrary complex-valued equations as you acquire response functions. Easily graph a system’s output over input to make precise two-port impedance response measurements.

Lock-in amplifier's LabVIEW boxed

Engineered to work seamlessly with your favorite APIs

API integration with MATLAB, LabVIEW, and more allows straightforward automation of your Moku device in complex setups or for repetitive tasks. Save your measurements, screenshots, traces, and other settings locally or to your preferred cloud app. You can also send work to yourself or colleagues within the Moku app.
