Data Logger overview

Moku:Lab’s Data Logger enables you to log data directly to an SD card for long-term measurements at rates of up to 100 kS/s, where the duration is limited only by the capacity of the SD card. Data can also be acquired at up to 1 MS/s by saving directly to Moku:Lab’s internal memory. Data saved to Moku:Lab’s internal memory can be uploaded to the cloud for analysis once the measurement is complete.

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?

Moku:Lab's Data Logger 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').
