Ubuntu 18.04, python3.6, use trunk https://github.com/scottprahl/RigolWFM.git Osciloscope: DS1102E Signals: DS1102E-signals.zip

test file:

$ cat test.py 
import sys
import RigolWFM.wfm as rigol
model = "DS1102E"
filename = sys.argv[1]
scope_data = rigol.Wfm.from_file(filename, model)
description = scope_data.describe()
print(description)

Got error:

If I swith type to DS1102D it works, but shows invalid amplitude scale. Pulse voltage should be 3V

Fixed. Try out v0.9.3. Thanks for the bug report.
