Rigol DG800 Series Arbitrary Waveform Generators are 1-2 channel, 10-36MHz high-resolution (16bit) signal generators with up to 8 Mpts waveform memory. Thanks to fan-less design, these units are completely silent.

These units appear to me using same hardware (just different color chassis) and firmware as Rigol DG900 Series signal generators.

Notable limitation when compared to Rigol DG1000z series is that Frequency Counter cannot be used simultaneously with second channel (CH2) is active. This only affects the 2 channel units (DG812, DG822, DG832).

Devices

Hardware on all these models is identical, only difference is in software/firmware.

Model Channels Max Frequency (Sine) Max Frequency (Square) Arbitrary Waveform Length Frequency Counter
DG811 1 10 MHz 5 MHz 2 Mpts Y
DG812 2 10 MHz 5 MHz 2 Mpts Y
DG821 1 25 MHz 10 MHz 2 Mpts Y
DG822 2 25 MHz 10 MHz 2 Mpts Y
DG831 1 35 MHz 10 MHz 2 Mpts Y
DG832 2 35 MHz 10 MHz 2 Mpts Y

Example use

Depending on your type of connection you have to can either use the USBTMC connection parameter or the TCP/IP connection parameter. Examples:


 -d rigol-dg

(usually no parameters are needed when connecting via USB)

When connecting over TCP/IP need to specify ip address and port:

 -d rigol-dg:conn=tcp-raw/192.168.42.42/5555

Check the capabilities of the meter's driver, and current state of settings:

 $ sigrok-cli -d rigol-dg --show

Check the capabilities specific to a channel (1 or 2):

 $ sigrok-cli -d rigol-dg -g 1 --show


Enable or disable channel output (first channel):

 $ sigrok-cli -d rigol-dg -g 1 --set --config enabled=true
 $ sigrok-cli -d rigol-dg -g 1 --set --config enabled=false

Get or set the waveform function (second channel):

 $ sigrok-cli -d rigol-dg -g 2 --get pattern
 $ sigrok-cli -d rigol-dg -g 2 --set --config pattern=square

Get or set the output signal frequency:

 $ sigrok-cli -d rigol-dg -g 1 --get output_frequency
 $ sigrok-cli -d rigol-dg -g 1 --set --config output_frequency=20000

Get or set the output signal amplitude:

 $ sigrok-cli -d rigol-dg -g 1 --get amplitude
 $ sigrok-cli -d rigol-dg -g 1 --set --config amplitude=3.3

Get or set the output signal offset:

 $ sigrok-cli -d rigol-dg -g 1 --get offset
 $ sigrok-cli -d rigol-dg -g 1 --set --config offset=1.0

Get or set the output signal phase:

 $ sigrok-cli -d rigol-dg -g 1 --get phase
 $ sigrok-cli -d rigol-dg -g 1 --set --config phase=90.0

Get or set the output signal duty cycle:

 $ sigrok-cli -d rigol-dg -g 1 --get output_duty_cycle
 $ sigrok-cli -d rigol-dg -g 1 --set --config output_duty_cycle=25.0


Acquire measurement data (frequency counter output):

 $ sigrok-cli -d rigol-dg --continuous
 $ sigrok-cli -d rigol-dg --time 10s
 $ sigrok-cli -d rigol-dg --samples 10
