Example use

Depending on your type of connection you have to can either use the RS232 connection parameter or the GPIB connection parameter. Examples:

 --driver=scpi-dmm:conn=/dev/ttyUSB0

or

 --driver=scpi-dmm:conn=libgpib/hp34401a

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

 $ sigrok-cli -d scpi-dmm:conn=/dev/ttyUSB0 --show

Get or set the meter's current function:

 $ sigrok-cli -d scpi-dmm:conn=/dev/ttyUSB0 --get measured_quantity
 $ sigrok-cli -d scpi-dmm:conn=/dev/ttyUSB0 -c measured_quantity=voltage/dc --set

Acquire measurement data, in the current mode or in another specified mode:

 $ sigrok-cli -d scpi-dmm:conn=/dev/ttyUSB0 --continuous
 $ sigrok-cli -d scpi-dmm:conn=/dev/ttyUSB0 --time 10s
 $ sigrok-cli -d scpi-dmm:conn=/dev/ttyUSB0 --samples 10 -c measured_quantity=current/dc
