Little Python helper class to read .trc binary files from LeCroy Oscilloscopes. Tested on Python3.
Just copy the readTrc.py file in your python path.
from readTrc import Trc
trc = Trc()
fName = "./C1_00000.trc"
datX, datY, d = trc.open(fName)
plot(datX, datY)
print(d)
# Or alternatively
plot(trc.x, trc.y)
print(trc.d)Note that in the above example d is a dictionary which contains the metadata.
