SOURce:POWer Subsystem
This subsystem contains the commands for setting the output level, level control and level correction of
the RF signal. Other units can also be used instead of dBm:
- by entering the unit directly after the numerical value (example :POW 0.5V),
- by changing the DEFault unit in the UNIT system (see the command UNIT:POWER).
The keyword SOURce is optional with commands and can be omitted.
