QCoDeS Example with the Rigol DG 1062 Instrument

import time

from qcodes.instrument_drivers.rigol import RigolDG1062

Instantiate the driver

gd = RigolDG1062("gd", "TCPIP0::169.254.187.99::INSTR")

Connected to: Rigol Technologies DG1062Z (serial:DG1ZA195006397, firmware:03.01.12) in 0.18s

Basic usage

Accessing the channels

gd.channels[0]
# Or...
gd.ch1

<DG1062Channel: gd_ch1 of DG1062: gd>

Trun the output for channel 1 to “on”

gd.channels[0].state(1)
# This is idential to
gd.ch1.state(1)

With apply we can check which waveform is being generated now, for example on channel 1

gd.channels[0].current_waveform()

{'waveform': 'SIN', 'freq': 1000.0, 'ampl': 1.0, 'offset': 0.0, 'phase': 0.0}

We can also change the waveform

gd.channels[0].apply(waveform="SIN", freq=2000, ampl=0.5, offset=0.0, phase=0.0)

Change individual settings like so:

gd.channels[0].offset(0.1)

This works for every setting, except waveform, which is read-only

gd.channels[0].waveform()

'SIN'

try:
    gd.channels[0].waveform("SIN")
except NotImplementedError:
    print("We cannot set a waveform like this ")

We cannot set a waveform like this

We can however do this:

gd.channels[0].sin(freq=1e3, ampl=1.0, offset=0, phase=0)

To find out which arguments are applicable to a waveform:

Find out which waveforms are available

print(gd.waveforms)

['HARM', 'NOIS', 'RAMP', 'SIN', 'SQU', 'TRI', 'USER', 'DC', 'ARB']

Setting the impedance

gd.channels[1].impedance(50)

gd.channels[1].impedance()

50.0

gd.channels[1].impedance("HighZ")

Alternatively, we can do

gd.channels[1].impedance("INF")

gd.channels[1].impedance()

'HighZ'

Sync commands

gd.channels[0].sync()

'ON'

gd.channels[0].sync("OFF")

Alternativly we can do

gd.channels[0].sync(0)

gd.channels[0].sync()

'OFF'

gd.channels[0].sync(1)

Alternativly we can do

gd.channels[0].sync("ON")

gd.channels[0].sync()

'ON'

Burst commands

Internally triggered burst

# Interal triggering only works if the trigger source is manual
gd.channels[0].burst.source("MAN")

# The number of cycles is infinite
gd.channels[0].burst.mode("INF")

If we want a finite number of cycles:

gd.channels[0].burst.mode("TRIG")
gd.channels[0].burst.ncycles(10000)

Setting a period for each cycle:

gd.channels[0].burst.period(1E-3)

# Put channel 1 in burst mode
gd.channels[0].burst.on(1)
# Turn on the channel. For some reason, if we turn on the channel
# immediately after turning on the burst, we trigger immediately.
time.sleep(0.1)
gd.channels[0].state(1)

# Finally, trigger the AWG
gd.channels[0].burst.trigger()

extranally triggered burst

gd.channels[0].burst.source("EXT")

Setting the idle level

# Set the idle level to First PoinT
gd.channels[0].burst.idle("FPT")

# We can also give a number
gd.channels[0].burst.idle(0)
