Version 1.7.4 released

We are pleased to announce the release of our latest instrument! Moku:LaserLockBox can be used to stabilize a laser's frequency to a reference cavity or atomic transition using high-performance modulation locking techniques.


  • Generate and output modulation signals at up to 200 MHz

  • Demodulate the input signal with an internal or external local oscillator including a phase-locked loop option

  • Scan across resonances with sawtooth or triangle waveforms at up to 1 MHz

  • Quickly lock to any zero-crossing in the error signal using the 'tap-to-lock' feature

  • Filter the demodulated input signal with up to fourth order infinite-impulse response filters

  • Individually configure fast and slow PID controllers

  • Observe signals at different stages in the signal processing chain using an in-built oscilloscope

Other improvements in this version include:

  • Moku:ArbitraryWaveformGenerator now supports triggering, with N-cycle and Start burst modes which can be triggered using an external trigger signal. In addition, Moku:ArbitraryWaveformGenerator now gives you full control over the number of points, update rate and interpolation of waveforms. There is also a new cardiac waveform for simulating ECG patterns, and a new graphical piecewise equation editor which makes building custom waveforms easier than ever.

  • Moku:DigitalFilterBox adds extended ranges for lowpass, highpass and bandstop filters, allowing corner frequencies up to six orders of magnitude below the sampling rate.

  • New-look main menu with options to connect to a recently-used device, switch instruments directly or open the file manager to view, upload and share data files on your device.

  • Minor bugfixes, interface improvements and performance enhancements.

We want to hear from you! If you have feedback, bug reports or feature requests, please send them to
