Project description


Library to communicate and parse .trc files with/from LeCroy oscilloscopes.

This library is based on previous work:


  • remote control LeCroy oscilloscopes over vxi11
    • does not require additional drivers (no visa)
    • controlling trigger settings
    • accessing statistics
    • downloading screenshots
    • view and donwload waveform data
  • parse LeCroy .trc waveform data
    • support for sequence mode
    • x and y units


lecroyutils is available in the Python Package Index (PyPi). It may be installed with pip:

> pip install lecroyutils


from import LecroyScopeData

# Parse a local .trc file
data = LecroyScopeData.parse_file('C2_00000_Lecroy.trc')

from lecroyutils.control import LecroyScope, TriggerMode, TriggerType

# Connect to a scope over vxi11
scope = LecroyScope('')
scope.trigger_type = TriggerType.edge
scope.trigger_source = 'C1'
data = scope.waveform('C1')

scope.save_waveform('C1', 'C1_00000_Lecroy.trc')
