SOURce Subsystem
SOURce Subsystem
The SOURce keyword is optional in many commands that set parameters for a source or output channel.
Example
The SOURce keyword and the channel number are optional in the [SOURce[1|2]:]AM[:DEPTh]? query, and if it is
omitted, the source defaults to channel 1. The following table shows how various forms of the query are interpreted.
Parameter Typical Return
AM:DEPTh? returns the modulation depth of channel 1
SOUR1:AM:DEPTh? returns the modulation depth of channel 1
SOUR2:AM:DEPTh? returns the modulation depth of channel 2 (two-channel instruments only)

their individual subsystems, below:
