readTrc
Little Python helper class to read .trc binary files from LeCroy Oscilloscopes. Tested on Python3.
Installation
Just copy the readTrc.py file in your python path.
Usage
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.
