Log voltage data and upload files directly to the cloud, all from an intuitive iPad interface, or with Python and MATLAB (LabVIEW coming soon).

Overview

Features


  • Log voltage data on two independent channels to an SD card for long-term measurements, or directly to Moku:Lab’s internal RAM for short, high-speed bursts
  • Built-in two-channel 250 MHz waveform generators
  • File formats: Plain text (csv) or binary, depending on data acquisition rate
  • Export modes: SD card, Dropbox, Email, iCloud, or the iPad “My Files” folder
  • Schedule a log to start after a delay of up to 10 days

Specifications


  • Log at up to 100 kS/s to an SD card, up to the card’s capacity (16 GB SD card included)
  • Log at up to 1 MS/s directly to Moku:Lab’s internal memory (500 MB RAM)
  • Input voltage range: 1 Vpp or 10 Vpp
  • Input impedance: 50 Ω or 1 MΩ
  • Input coupling: AC or DC

F.A.Q.


  • How long can I record for?

    The Moku:Datalogger is limited only by storage. The Moku:Lab has 500MB of internal storage and can also log to an SD card of any size. Note though that most SD cards use the FAT32 filesystem, which is limited to a maximum file size of 4GB.

    Recording a single channel at minimum rate to a binary file, this gives you approximately 4 months of recording to internal storage, up to 2.5 years to an SD card.


  • How can I read data from .li files?

    The LI File Converter can be used to convert binary data from a .li file into plain text data in CSV (comma-separated values) format, or to a MATLAB .mat file. You can download it at liquidinstruments.com/utilities/


  • How can I import a CSV file from Moku:Datalogger into MATLAB?

    If you only need the data itself, simply type load yourfile.csv at the MATLAB command prompt. CSV files generated by Moku:DataLlgger also contain a text header with information about when the data was recorded, the instrument settings, and what each column in the data represents. If you want to import this metadata as well, use the command moku = importdata('yourfile.csv').
