RocketLogger Python Support

Project description

RocketLogger Python Support Library

This package provides RocketLogger data file handling support, as well as basic processing and plotting of the data. Further, it provides the necessary support to generate calibration data from measurements.


  • Python 3: version 3.6-3.11
  • NumPy: version 1.13-1.25

Optional dependencies

  • Matplotlib: for plotting data overview
  • pandas: for pandas DataFrame export


  • Data processing: supports all officially specified RLD file version (versions 2-4)
  • Calibration: compatible with RocketLogger calibration file version 2


The package is available from the Python Package Index Install the package using pip:

python -m pip install rocketlogger

Getting Started

RocketLogger Data Processing

To import a RocketLogger data (*.rld) file, use the RocketLoggerData class:

>>> from import RocketLoggerData
>>> rld = RocketLoggerData('data.rld')

To merge channels with auto-ranging, i.e. the current channels:

>>> rld.merge_channels()

To get the loaded channel data (by name) and corresponding timestamps:

>>> d = rld.get_data(['V1', 'I1'])
>>> t = rld.get_time()

For more details about the individual functions and their parameters, refer to the documentation available at

RocketLogger Device Calibration

The RocketLoggerCalibration class from the rocketlogger.calibration module provides the necessary support for generating RocketLogger device calibration. See the Calibration wiki section for more details on the calibration procedure.


The documentation for the RocketLogger is found in the wiki pages at
