Trigger Scope
The Trigger Scope specifies the scope of the triggering, whether it is for all

When this function is enabled with a value of "ACTive", only active channel
is triggered. When this function is enabled with a value of "ALL", all
channels of the E5071C are triggered.
For example, if Trigger Scope is set to "ACTive" when Trigger > Continuous
is selected for all channels, a measurement channel is automatically
changed by switching over the active channel.
