Version 1.5.3 released

This version brings major upgrades to Moku:LockInAmplifier, Moku:Phasemeter and Moku:WaveformGenerator.

Lock-In Amplifier

  • Demodulate using an external signal with optional phase-locked loop (PLL)

  • Amplify small input signals by up to 48 dB before demodulation

  • Output a second filtered signal or an independent local oscillator

  • Convert demodulation output from XY to polar coordinates

  • Add a PID controller to the output signal

  • Log data to SD card or RAM


  • Extended frequency range down to 1 kHz

  • New advanced spectral analysis tools (PSD, coherence, Allan Variance and more)

  • Increased sample rates up to 125 kHz

  • Free-wheeling: loop 'free-wheels' at the last known good frequency when the input signal is lost, improving reacquisition time and providing clock recovery functionality for communications systems

  • Improved gain scaling with selectable unity gain frequencies from 10 Hz to 10 kHz

  • Improved lock consistency at high gain settings

  • Phase-locked outputs: output a sine wave that is phase-locked to the input signal

Waveform Generator

  • Added burst mode (N cycle, Gated or Start) triggered from internal or external source

  • Added sweep mode triggered from internal or external source


  • iOS 11 compatibility

  • Select interface language independently from the iPad default

  • Display reference traces in Moku:BodeAnalyzer
    (renamed to "Frequency Response Analyzer" as of July 2019 )

  • New options to save waveform data in multiple different formats

  • Transfer log files directly from device RAM to SD card

  • Fixed localization issues

  • Minor bugfixes and performance enhancements
