Rigol DG1000Z arbitrary waveform generator Python library (unofficial)

A simple Python library and utility to control Rigol DG1000Z arbitrary waveform generator. This library implements the functiongenerator class from the pylabdevs package which exposes the public interface.

Installing

There is a PyPi package that can be installed using

pip install pydg1000z

Simple example to generate waveforms:

import time
from pydg1000z import *
from labdevices.scpi import SCPIDeviceEthernet
from labdevices.functiongenerator import FunctionGeneratorWaveform

with PYDG1000Z(address="10.0.0.124") as awg:

  awg.set_channel_enabled(0, True)
  awg.set_channel_enabled(1, True)

  awg.set_channel_frequency(0, 600000)
  awg.set_channel_waveform(channel=0, waveform=FunctionGeneratorWaveform.SINE)
  awg.set_channel_waveform(channel=1, waveform=FunctionGeneratorWaveform.SINE)

  awg.set_channel_amplitude(0, 5.0)
  awg.set_coupling(True)

  awg.set_channel_frequency(0, 1000)
  time.sleep(10)

  awg.set_channel_frequency(0, 10000)

  print("Press Key to switch off")
  input()

  awg.set_channel_enabled(0, False)
  awg.set_channel_enabled(1, False)

Supported waveforms

• FunctionGeneratorWaveform.SINE : Set the waveform of the specified channel to sine waveform with the specified frequency, amplitude, offset and phase
• FunctionGeneratorWaveform.SQUARE : Set the waveform of the specified channel to square waveform with the specified frequency, amplitude, offset and phase.
• FunctionGeneratorWaveform.RAMP : Set the waveform of the specified channel to ramp waveform with the specifiedfrequency, amplitude, offset and phase.
• FunctionGeneratorWaveform.TRGL : Set the waveform of the specified channel to triangle waveform with the specified frequency, amplitude, offset and phase.
• FunctionGeneratorWaveform.DC : Set the waveform of the specified channel to DC with the specified offset.
• FunctionGeneratorWaveform.WHITENOISE : Set the waveform of the specified channel to noise with the specified amplitude and offset.
