Measure the frequency response of a system or device under test (DUT) in both magnitude and phase using a swept sine output from 10 mHz to 500 MHz. Characterize filters, measure impedance, or determine s-parameters of multi-port networks — all visualized through an intuitive Bode plot interface.
Streamline frequency response testing with software-defined solutions such as automated Bode plot measurements and LabVIEW APIs.
The Frequency Response Analyzer (FRA) makes system characterization easier than ever. Measure the transfer functions of electrical, mechanical, or optical systems to optimize the closed-loop response of control systems, characterize resonant behavior in nonlinear systems, design filters, and measure the bandwidth of different electronic or optical components.
Use vector measurements across fundamental and harmonics to characterize non-linear effects.
Probe up to four systems simultaneously with Moku:Pro, or up to four ports on one system.
Find open- and closed-loop transfer functions for power supply stability analysis and more.
The only Frequency Response Analyzer with Dynamic Amplitude adjustments. Automatically check every point in the sweep for saturation, lowering the output signal amplitude until saturation is no longer detected on the corresponding input. Make accurate Bode plot measurements without sacrificing dynamic range, even when measuring signals whose amplitude response varies strongly with frequency.
Customize your analysis with a wide range of settling and averaging times, one-touch normalization to remove cable spurs, and a configurable math channel. Drag-and-drop cursors to rapidly measure exact values. Once you’re done testing, save the data and share it with teammates from the app.
With the Frequency Response Analyzer, you can make common frequency response measurements at a fraction of the cost of other solutions, all with the power of 15+ additional instruments built in. Perform measurements such as:
