FAQ

Can Moku handle both driving and sensing tasks for MEMS characterization and closed-loop control?

Yes. Multi-Instrument Mode allows you to use one device to simultaneously generate a drive signal, using the Waveform Generator, and measure the response, using either the Lock-in Amplifier, Oscilloscope, or Phasemeter. This makes it ideal for characterizing MEMS resonators, performing Q-factor measurements, or closing feedback loops in inertial sensing applications, without needing to chain together separate instruments.

How well does Moku handle small signal detection from high-impedance MEMS sensors?

Moku devices use ADC blending techniques on its analog frontend to maximize noise performance, with adjustable coupling, impedance, and attenuation.This allows precise detection of small voltage or current outputs typical of piezoelectric or capacitive MEMS devices. For especially weak signals, the Lock-in Amplifier can extract amplitude and phase information well below the noise floor, making it a powerful tool for MEMS displacement or motion sensing.

Can one automate MEMS test procedures with Moku for production or repeatable R&D processes?

Yes. The Moku Python API lets you automate every step of your measurement process, from stimulus generation and parameter sweeps to data logging and result analysis. You can integrate it with existing software stacks or production benches without needing low-level drivers, enabling repeatable, scriptable testing for MEMS validation.
