Moku:Lab iPad app Version 1.8.2 released

Liquid Instruments is pleased to announce an update to Moku:Lab

To update your Moku:Lab and its instruments, please visit the iOS App Store and update the Moku:Lab app to v1.8.2

The iOS update contains the updates to Moku:Lab instruments; once the app is updated, the instruments will update next time the app connects to Moku:Lab.

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

New features in Moku:Lab’s Frequency Response Analyzer (formerly Bode Analyzer)

  • Moku:Lab’s Bode Analyzer is renamed to Frequency Response Analyzer

  • Can set phase difference between outputs

  • Can demodulate at up to 15th harmonic

  • Can measure input as well as input/output

  • Can specify output amplitude in dBm

New features in Moku:Lab’s Waveform Generator

  • Ramp and pulse waveforms can now be modulated using FM, PM, burst or sweep mode

  • Phase of pulse waveforms can be changed

  • New duty cycle option for square waves

  • Waveform phase can now be changed in sweep mode

  • Can select 50 Ohm or 1 MOhm output load

  • Can modulate and trigger from either input channel

Improvements to data logging capabilities

  • Can now log data in Moku:Lab’s PID Controller, Digital Filter Box, FIR Filter Builder and Laser Lock Box

  • Can change logging rate directly in logging panel

  • Can edit log file name (a timestamp will be appended to ensure filename is unique)

The embedded waveform generators in Moku:Lab’s Oscilloscope and Data Logger also have some new features

  • Can select 50 Ohm or 1 MOhm output load

  • New duty cycle option for square waves

  • New sync phase option

New floating drawer sections

  • Tap-and-hold on any section in a settings drawer to detach it and drag it anywhere on the screen

  • Double-tap the title bar to choose which rows are displayed and which are hidden; great for saving screen real estate

General improvements

  • New-look block diagrams in Moku:Lab’s Lock-in Amplifier and Laser Lock Box

  • New buttons to quickly adjust phase parameters by +/- 90 degrees in number pad

  • New autoscale option in Moku:Lab’s Phasemeter's timeseries graph

  • Transients in Moku:Lab’s Phasemeter's timeseries are automatically removed on reacquire

  • New cascaded first-order filter type for smooth time-domain response in Moku:Lab’s Digital Filter Box

  • Filter corner frequency can now be changed to time constant in Moku:Lab’s Lock-in Amplifier

  • Equation waveforms in Moku:Lab’s Arbitrary Waveform Generator are now restored when connecting to a running instrument

  • Input range can now be set in volts instead of as an attenuation in Moku:Lab’s Spectrum Analyzer and Frequency Response Analyzer

  • Improvements to triggering on high-frequency signals in Moku:Lab’s Oscilloscope when using Gaussian interpolation

  • Fixed a problem which could cause error 103 when deploying an instrument for the first time after a reboot

  • Moku:Lab’s Frequency Response Analyzer no longer clears the frame when saving data or at the end of a sweep with fewer than 512 points

  • Minor bugfixes, interface improvements and performance enhancements
