readTrc

Little Python helper function to read .trc binary files from LeCroy Oscilloscopes. Tested on Python3.

Installation

Just copy the readTrc.py file in your python path.

Usage

import readTrc
fName = "./C1_00000.trc"
datX, datY, m = readTrc.readTrc( fName )

Note that in the above example m is a dictionary which contains the metadata. For example:
