Example Python script to implement the Oscilloscope
#
# pymoku example: Basic Oscilloscope
#
# This script demonstrates how to use the Oscilloscope instrument
# to retrieve a single frame of dual-channel voltage data.
#

#
from pymoku import Moku
from pymoku.instruments import Oscilloscope
# Connect to your Moku by its device name
# Alternatively, use Moku.get_by_serial('#####') or Moku('192.168.###.###')
m = Moku.get_by_name('Moku')
try:
i = m.deploy_or_connect(Oscilloscope)
# Span from -1s to 1s i.e. trigger point centred
i.set_timebase(-1, 1)
# Get and print a single frame worth of data (time series
# of voltage per channel)
data = i.get_data(timeout=10)
print(data.ch1, data.ch2, data.time)
finally:
m.close()
