Digital Filter Box

Leverage the versatility and performance of the Moku Digital Filter Box to interactively design and generate a range of infinite impulse response filters. For maximum flexibility, select from lowpass, highpass, bandpass, and bandstop filter shapes with up to seven fully configurable filter types, including Butterworth, Chebyshev, and elliptic. Deploy this instrument independently or as a part of a Multi-instrument Mode configuration to streamline your workflow anywhere you need to test.

The Moku Digital Filter Box is easy to use and offers a range of advanced capabilities to optimize your experiment — at the most cost-effective price in the industry.

Add a filter stage to your custom test system to unlock greater insights

Deploy the Moku Digital Filter Box as a standalone instrument or integrate it in with your test sequence in Multi-instrument Mode. Pair it with other software-defined instruments to filter inputs, outputs, or intermediate signals.

Visualize your system and configuration in real time

Quickly design your filter’s frequency response using the interactive Bode plot. Need to adjust filter parameters? Just tap and drag the corner frequencies.

For total flexibility, select from preset filters or build your own

Choose from lowpass, highness, bandpass, and bandstop filter shapes with up to seven filter types including Butterworth, Chebyshev, and elliptic, or build your own custom filters.

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.

Engineered for demanding applications

You can’t innovate for the future when your test equipment is stuck in the past. Use the Moku Digital Filter Box to accelerate development timelines with speed and flexibility unmatched by any other instrument in its class.
