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
