Frequency Response Analyzer

The Moku Frequency Response Analyzer enables multi-channel Bode analysis in a single device. Leverage up to four inputs and outputs to enable differential or ratiometric measurements. Quickly measure the frequency response or transfer function of a device under test with industry-leading noise performance and bandwidth to see the real performance of your DUT on an integrated Bode plot. With advanced functionality included, it’s easy to optimize your measurement dynamic range, prevent saturation, and log data simultaneously.

Make fast, accurate stimulus-response measurements with the Moku Frequency Response Analyzer

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 to probe up to four systems simultaneously, or one system at four points. Perform many VNA-type measurements including impedance testing, s-parameter testing, and more.

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.

Live Bode plots for real-time frequency response analysis

Monitor the magnitude and phase on the interactive Bode plot to make measurements across fundamental and harmonics to characterize nonlinear effects. Use the configurable math channel for real-time addition, subtraction, and division, or to calculate arbitrary complex-valued equations as you acquire response functions.

Prevent saturation without sacrificing dynamic range

The Moku Frequency Response Analyzer is the only Bode analyzer with Dynamic Amplitude mode, checking every point in the 8192-point sweep for saturation and automatically reducing the corresponding output signal amplitude until saturation is no longer detected.
