Couplings The frequency reference state is coupled to the frequency reference set immediate action. When the
reference set immediate action key is pressed, or the SCPI command issued, it turns the frequency
reference state ON

6.1.9.6 Freq Offset
Lets you specify the frequency offset value. When the frequency offset state is ON,
an annunciator is displayed on the main source view to indicate this state.
When the frequency offset is set to zero (0) and you set a new offset value, the
displayed frequency value changes as follows, and the RF output frequency does
not change:
Displayed value = output frequency + offset value
Where:
–
output frequency equals the original frequency entered under Source,
Frequency, Frequency
–
offset value equals the value entered under Source, Frequency, Freq Offset
