Rigol DG900 Series Arbitrary Waveform Generators are 2 channel, 50-100MHz high-resolution (16bit) signal generators with 16 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 DG800 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.

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
DG952	2	50 MHz	15 MHz	16 Mpts	Y
DG972	2	70 MHz	20 MHz	16 Mpts	Y
DG992	2	100 MHz	25 MHz	16 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**
