6.1.6.3 Power Ref
Lets you toggle the state of the power reference. When you use a power reference,
the signal generator outputs an RF power that is set relative to the reference power
by the value entered under Source>Amplitude>RF Power as follows:
Output power = reference power + entered power
Where:
–
reference power equals the original RF Power entered under
Source>Amplitude>RF Power and set as the reference power
–
entered power equals a new value entered under Source>Amplitude>Amptd
Offset
For more information on Reference Frequency, see "Set Reference Power" on page
2022.
