Oscilloscope Auto Range
Published June 2nd, 2026 by Dylan Perez
The oscilloscope's frontend settings can be adjusted, such as the impedance, bandwidth, coupling, and the voltage range. Each hardware unit has selectable voltage ranges that differ between hardware. There is also an ‘Auto’ range feature, which will automatically select the range for a given signal. Voltage ranges for the Moku:Pro The range that is
Saving and uploading instrument configuration files with Moku API
Published September 22nd, 2025 by Dylan Perez
The ability to save multiple instrument configuration files and upload them to any Moku is a new feature in MokuOS 4.0.1, and with the release of 4.0.2, users can now save and upload instrument configuration files with the Moku API. Each instrument now has a function called save_settings()/load_settings() which gives the ability to save the instrum
Manually triggering waveforms simultaneously
Published October 21st, 2025 by Dylan Perez
The ability to manually trigger waveforms is available in the Moku app and API libraries. This feature allows multiple phase synchronized waveforms to be triggered simultaneously. This was previously only available with an external trigger signal. Moku App Configure the waveform generator to have ‘Burst’ modulation and configure the trigger to ‘Man
How does streaming work on Moku?
Published June 23rd, 2025 by Dylan Perez
The Data Logger can log data with the Moku app or API, or stream data over the network via the API. Logging collects data over time, storing the data on Moku. Users can download the data in multiple formats and process as needed. Streaming sends data from the Moku to a PC in real time, bypassing the need for storing the data. Datalogging using the D
Dynamic Amplitude Adjustment
Published December 13th, 2024 by Dylan Perez
The Dynamic amplitude setting in the Frequency Response Analyzer is a powerful tool that allows you to get the most accurate frequency response of your device under test (DUT). When using the frequency response analyzer, the signal going to your DUT should usually have the largest amplitude possible to ensure that you have a high resolution curve. H
How to save and upload configuration files
Published August 13th, 2025 by Dylan Perez
With the release of MokuOS 4.0, users now have the ability to save multiple multi-instrument configurations and upload them to any Moku device. First, create a multi-instrument configuration: Then, navigate to the menu on the top left and select ‘Save configuration…’. Next, choose the name and destination for the .mokuconf file: To load configurat
Phasemeter Acquisition Rate
Published January 6th, 2026 by Dylan Perez
The Phasemeter has a parameter ‘Acquisition Rate’ which goes up to 152 kSa/s on the Moku:Delta. This is the data logging rate, not the sample rate of the instrument. When used in single instrument mode, the Phasemeter will sample at the full sample rate of the instrument, which depends on the hardware. Moku:Delta's Phasemeter will sample each channe
Configuring PLL (Phase-locked loop) Demodulation with Python API
Published September 22nd, 2025 by Dylan Perez
The Moku Lock-In Amplifier has four demodulation options; None, Internal, External, or External PLL (phase-locked loop). The External PLL option will track the frequency of the second input signal and use the resulting signal as the demodulation signal. This can be easily configured in the Moku app by navigating to the ‘Settings’ drawer on the top r
How to use 'Multiple Starts' setting in the Time & Frequency Analyzer
Published December 12th, 2025 by Dylan Perez
The ‘Multiple Starts’ setting in the Time & Frequency Analyzer (TFA) is new with MokuOS 4.1. The TFA works by calculating the interval between a start and stop event. By default, the TFA will timestamp the first ‘start’ event, and calculate the interval to the ‘stop’ event. In some experiments, there may be multiple start events before a stop ev
How to convert voltage units to phase units from the Lock-In Amplifier
Published April 8th, 2025 by Dylan Perez
Liquid Instrument's Lock-In Amplifier (LIA) can recover amplitude and phase information from a low signal-to-noise ratio (SNR) signal. The LIA can recover the in-phase (X) and quadrature (Y) component of your signal, or can be switched to polar mode which will output the amplitude (R) and phase ( Θ) of your signal. When the LIA is set to Θ mode, the
Output Impedance of Moku
Published March 26th, 2025 by Dylan Perez
Each Moku device has a fixed output impedance. On the Moku:Delta, Moku:Pro, and Moku:Lab, the output impedance is 50 Ω. On the Moku:Go, the output impedance is 200 Ω. On the Moku:Delta, Moku:Pro, and Moku:Lab, some instruments allow you to set the impedance of the load being driven when using them in single instrument mode. One example of this is t
How to download bitstream files with mokucli
Published September 22nd, 2025 by Dylan Perez
It's now possible to use mokucli to download the instrument bitstreams using: mokucli instrument download <MokuOS_version> This will automatically make the bitstreams available for all API packages. Users can also use mokucli to download bitstream files to a specified directory. To do this, run the command: mokucli instrument download <M
Connecting to Moku via API Using Serial Number
Published January 23rd, 2025 by Dylan Perez
Using the Moku API to connect to and configure your Moku is straightforward and well documented on our API documentation site (https://apis.liquidinstruments.com). Typically, users will opt to use the IPv4 or IPv6 address of the Moku to point to the device to connect to in the script. ## This is an example of connecting to Moku using the IPv4 addre
